Preface
Thank you for choosing DELTA’s high-performance VFD-E Series. The VFD-E Series is
manufactured with high-quality components and materials and incorporate the latest microprocessor
technology available.
This manual is to be used for the installation, parameter setting, troubleshooting, and daily
maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the following
safety guidelines before connecting power to the AC motor drive. Keep this operating manual at
hand and distribute to all users for reference.
To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor
drive are to do installation, start-up and maintenance. Always read this manual thoroughly before
using VFD-E series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.
Failure to comply may result in personal injury and equipment damage. If you have any questions,
please contact your dealer.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

DANGER!
1.
2.

AC input power must be disconnected before any wiring to the AC motor drive is made.
A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power
has been turned off. To prevent personal injury, please ensure that power has turned off before
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage
levels.

Never reassemble internal components or wiring.

The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and
W/T3 directly to the AC mains circuit power supply.

Ground the VFD-E using the ground terminal. The grounding method must comply with the laws
of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram.

VFD-E series is used only to control variable speed of 3-phase induction motors, NOT for 1phase motors or other purpose.

VFD-E series shall NOT be used for life support equipment or any life safety situation.

WARNING!
1.

DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive
easily damage by high-voltage.

There are highly sensitive MOS components on the printed circuit boards. These components
are especially sensitive to static electricity. To prevent damage to these components, do not
touch these components or the circuit boards with metal objects or your bare hands.

Only qualified persons are allowed to install, wire and maintain AC motor drives.

CAUTION!
1.
2.

Some parameters settings can cause the motor to run immediately after applying power.
DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,
high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic
particles.

Only use AC motor drives within specification. Failure to comply may result in fire, explosion or
electric shock.

To prevent personal injury, please keep children and unqualified people away from the
equipment.

When the motor cable between AC motor drive and motor is too long, the layer insulation of the
motor may be damaged. Please use a frequency inverter duty motor or add an AC output
reactor to prevent damage to the motor. Refer to appendix B Reactor for details.

The rated voltage for AC motor drive must be ≤ 240V (≤ 480V for 460V models) and the short
circuit must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models).

Chapter 1 Introduction|

RFI Jumper
RFI Jumper: The AC motor drive may emit the electrical noise. The RFI jumper is used to suppress
the interference (Radio Frequency Interference) on the power line.
Main power isolated from earth:
If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off.
Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage
(according to IEC 61800-3) and reduce earth leakage current.

CAUTION!
1.

After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore,
please make sure that main power has been switched off before cutting the RFI jumper.

The gap discharge may occur when the transient voltage is higher than 1,000V. Besides,
electro-magnetic compatibility of the AC motor drives will be lower after cutting the RFI
jumper.

Do NOT cut the RFI jumper when main power is connected to earth.

The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and
motor must be separated if high voltage test is performed and the leakage currents are
too high.

To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC
motor drive is installed on an ungrounded power system or a high resistance-grounded
(over 30 ohms) power system or a corner grounded TN system.

Operating, storing or transporting the AC motor drive outside these conditions may cause
damage to the AC motor drive.

2.
3.

Failure to observe these precautions may void the warranty!
Mount the AC motor drive vertically on a flat vertical surface object by screws. Other directions
are not allowed.

The AC motor drive will generate heat during operation. Allow sufficient space around the unit
for heat dissipation.

The heat sink temperature may rise to 90°C when running. The material on which the AC motor
drive is mounted must be noncombustible and be able to withstand this high temperature.

Chapter 1 Introduction|

When AC motor drive is installed in a confined space (e.g. cabinet), the surrounding
temperature must be within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive
in a space with bad ventilation.

Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the
heatsink.

When installing multiple AC more drives in the same cabinet, they should be adjacent in a row
with enough space in-between. When installing one AC motor drive below another one, use a
metal separation between the AC motor drives to prevent mutual heating.

1.2.2 DC-bus Sharing: Connecting the DC-bus of the AC Motor Drives
in Parallel
1.
2.

This function is not for VFD-E-T series.
The AC motor drives can absorb mutual voltage that generated to DC bus when
deceleration.

Enhance brake function and stabilize the voltage of the DC bus.

The brake module can be added to enhance brake function after connecting in parallel.

Only the same power system and capacity can be connected in parallel.

It is recommended to connect 5 AC motor drives in parallel (no limit in horsepower but
these 5 drives should be the same power system and capacity).

power s hould be applied at the same time
(only the same power sy stem and c apac ity can be connected in parallel)

Chapter 2 Installation and Wiring
After removing the front cover, check if the power and control terminals are clear. Be sure to observe
the following precautions when wiring.

General Wiring Information
Applicable Codes
All VFD-E series are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters
Laboratories (cUL) listed, and therefore comply with the requirements of the National
Electrical Code (NEC) and the Canadian Electrical Code (CEC).
Installation intended to meet the UL and cUL requirements must follow the instructions
provided in “Wiring Notes” as a minimum standard. Follow all local codes that exceed UL
and cUL requirements. Refer to the technical data label affixed to the AC motor drive and
the motor nameplate for electrical data.
The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for
each VFD-E Series part number. These fuses (or equivalent) must be used on all
installations where compliance with U.L. standards is a required.

CAUTION!
1.

Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply may
result in damage to the equipment. The voltage and current should lie within the range as
indicated on the nameplate.

All the units must be grounded directly to a common ground terminal to prevent lightning strike
or electric shock.

Please make sure to fasten the screw of the main circuit terminals to prevent sparks which is
made by the loose screws due to vibration.

Check following items after finishing the wiring:
A. Are all connections correct?
B. No loose wires?
C. No short-circuits between terminals or to ground?

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

2-1

Chapter 2 Installation and Wiring|

DANGER!
1.

A charge may still remain in the DC bus capacitors with hazardous voltages even if the power
has been turned off. To prevent personal injury, please ensure that the power is turned off and
wait ten minutes for the capacitors to discharge to safe voltage levels before opening the AC
motor drive.

Only qualified personnel familiar with AC motor drives is allowed to perform installation, wiring
and commissioning.

Make sure that the power is off before doing any wiring to prevent electric shock.

2.1 Wiring
Users must connect wires according to the circuit diagrams on the following pages. Do not plug a
modem or telephone line to the RS-485 communication port or permanent damage may result. The
pins 1 & 2 are the power supply for the optional copy keypad only and should not be used for RS-485
communication.

2.

The wiring of main circuit and control circuit should be separated to prevent erroneous actions.
Please use shield wire for the control wiring and not to expose the peeled-off net in front of the
terminal.

Please use the shield wire or tube for the power wiring and ground the two ends of the shield
wire or tube.

Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it
comes in contact with high voltage.

The AC motor drive, motor and wiring may cause interference. To prevent the equipment
damage, please take care of the erroneous actions of the surrounding sensors and the
equipment.

When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals
U/T1, V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation,
switch over any of the two motor leads.

Chapter 2 Installation and Wiring|

With long motor cables, high capacitive switching current peaks can cause over-current, high
leakage current or lower current readout accuracy. To prevent this, the motor cable should be
less than 20m for 3.7kW models and below. And the cable should be less than 50m for 5.5kW
models and above. For longer motor cables use an AC output reactor.

The AC motor drive, electric welding machine and the greater horsepower motor should be
grounded separately.

9.
10.

Use ground leads that comply with local regulations and keep them as short as possible.
No brake resistor is built in the VFD-E series, it can install brake resistor for those occasions
that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11.

Multiple VFD-E units can be installed in one location. All the units should be grounded directly
to a common ground terminal, as shown in the figure below. Ensure there are no ground
loops.

Make sure that the wiring is correct. In particular, check that the
output terminals U/T1, V/T2, W/T3. are NOT connected to power
and that the drive is well grounded.

Verify that no other equipment is connected to the AC motor drive

Do NOT operate the AC motor drive with humid hands.

Please check if READY LED is ON when power is applied. Check
if the connection is well when option from the digital keypad KPELE02.

It should be stopped when fault occurs during running and refer to
“Fault Code Information and Maintenance” for solution. Please do
NOT touch output terminals U, V, W when power is still applied to
L1/R, L2/S, L3/T even when the AC motor drive has stopped. The
DC-link capacitors may still be charged to hazardous voltage
levels, even if the power has been turned off.

The coefficient K determines the multiplying factor for the user-defined unit.
The display value is calculated as follows:
U (User-defined unit) = Actual output frequency * K (Pr.00.05)
Example:
If user wants to use RPM to display the motor speed when 4-polse motor runs at 60Hz. The
user can display the motor speed by setting Pr.00.04 to 0. The application is shown as follows.
From the formula of motor speed, user-defined unit (U) (RPM) = 60X120/4=1800 (disregard
slip). Therefore, User Defined Coefficient K is 30.0.

V/f Control

Vector Control

This parameter determines the control method of the AC motor drive.
Control of V/f (Voltage/frequency)
1. To operate by the change of frequency and voltage without changing the mechanical
characteristic of motor: it can run by open-loop method and also can use with PG card (refer to
Appendix B) to run by close-loop method. In this control, it gets the change of the
electromagnetic torque of rotor and the load torque from the change of slip ratio.
2. The V/f control is the constant value control mode. Although it prevents the main questions
of the decreasing frequency and increasing magnetic field, the magnetic field is decreasing
with frequency. In such circumstance, insufficient motor torque will occur when the magnetic
field weakens in the low frequency. At this moment, it can get the best operation with Pr.07.02
setting(Torque Compensation) to get the torque compensation.
common applications: pump, conveyor belt, compressor and treadmill
Vector control:
1. To operate by the change of frequency and voltage without changing the mechanical
characteristic of motor: it can run by open-loop method and also can use with PG card (refer to
Appendix B) to run by close-loop method. In this mode, it is coordinate change. The physical
essence is the relativity of motion. That means the change of rotor current only has relation
with electromagnetic torque and the change of stator current only has relation with
electromagnetic torque. This is the characteristic of vector control.
2.The vector control can eliminate the relation between electromagnetic current vector and
armature flux. Thus, it can control the current vector and armature flux independently to raise

This parameter determines the AC motor drive’s Maximum Output Frequency. All the AC
motor drive frequency command sources (analog inputs 0 to +10V and 4 to 20mA) are scaled
to correspond to the output frequency range.
Please note that output frequency may be not in this setting range due to parameter setting:
1. Pr.00.10 is set to 0: when enabling Pr.07.03 (Slip Compensation) in V/f mode, it may be not
in this setting range.
2. Pr.00.10 is set to 1: The AC motor drive will auto compensate slip in vector mode, so it also
may be not within this setting range.

This parameter must be equal to or greater than the Output Frequency Lower Limit (Pr.01.08).
The Maximum Output Frequency (Pr.01.00) is regarded as 100%.
Output Frequency Upper Limit value = (Pr.01.00 * Pr.01.07)/100.
The max. output frequency of the AC motor drive will be limited by this setting. If the setting of
frequency command is greater than Pr.01.07, the output frequency will be equal to or less than
Pr.01.07.
When enabling Pr.07.03 or Pr.10.00~10.13, the output frequency of the AC motor drive may
exceed the frequency command but it is still limited by this setting.

Output Frequency Lower Limit
Settings

0.0 to 100.0%

Factory Setting: 0.0

The Output Frequency Lower Limit value = (Pr.01.00 * Pr.01.08) /100.
This setting will limit the min. output frequency of the AC motor drive. When the frequency
command of the AC motor drive or the frequency calculated by feedback control is less than
this setting, the output frequency of the AC motor drive will be limited by this setting.
After starting running, the AC motor drive will accelerate from Pr.01.05 (Minimum Output
Frequency (Fmin) (Motor 0)) to the setting frequency by V/f curve and won’t be limited by this
setting.
The Upper/Lower Limits are to prevent operation errors and machine damage.
If the Output Frequency Upper Limit is 50Hz and the Maximum Output Frequency is 60Hz, the
Output Frequency will be limited to 50Hz.
If the Output Frequency Lower Limit is 10Hz, and the Minimum Output Frequency (Pr.01.05) is
set to 1.0Hz, then any Command Frequency between 1.0-10Hz will generate a 10Hz output
from the drive. If the command frequency is less than 1.0Hz, drive will be in ready status
without output.
This parameter must be equal to or less than the Output Frequency Upper Limit (Pr.01.07).

factory settings are acceleration time 1.
The Acceleration Time is used to determine the time required for the AC motor drive to ramp
from 0 Hz to Maximum Output Frequency (Pr.01.00). The Deceleration Time is used to
determine the time required for the AC motor drive to decelerate from the Maximum Output
Frequency (Pr.01.00) down to 0 Hz.
If the setting of the acceleration/deceleration time is too short, it may trigger the protection
(Pr.06.01(Over-Current Stall Prevention during Accel) or Pr.06.00(Over-Voltage Stall
Prevention)) and make the actual acceleration/deceleration time be larger than this setting.
If the setting of the acceleration time is too short, it may cause over-current during acceleration
and damage the motor or trigger the protection function.
If the setting of the deceleration time is too short, it may cause over-current during deceleration
or over voltage of the AC motor drive and damage the motor or trigger the protection function.
It can use suitable brake resistor to decelerate the AC motor drive in short time and prevent
internal over voltage. Refer to Appendix B for brake resistor.
When enabling Pr.01.17(Acceleration S-Curve) and Pr.01.18(Deceleration S-Curve), the

When this parameter is set to 5(Linear Accel. controlled by current, linear Decel.)/6(Linear
Accel. controlled by current, auto Decel.): the current value when the drive performs overcurrent stall prevention can be kept within the setting of stall prevention level. For example, if
the setting of stall prevention level is 100%, it will perform deceleration as the current exceeds
100% during operation and keep the current around 100%. Besides, it will perform
deceleration no matter over-current occurs during deceleration or constant speed. (The
present over-current stall prevention during acceleration is used to keep the output frequency
and prevent from the drive overload (OL).
When this parameter is set to 5(Linear Accel. controlled by current, linear Decel.): the drive will
perform the linear deceleration by the setting of deceleration time. When this parameter is set
to 6 (Linear Accel. controlled by current, auto Decel.), the drive stop the motor by the fastest
deceleration time after auto-distinguish load regenerative energy.

This simple position function is calculated by the measure of operation distance. When the
multi-function input terminal is set to 25 and it is ON, it will start to decelerate after getting the
delay time from Pr.01.20 to Pr.01.25 and get the final position.
This is simple position function NOT the precision position function.

Assume that the radius of the 4-pole motor is r and rotation speed is n (rpm).

Example 1:
Assume that motor speed is 50Hz, the delay time at 50Hz is 2 sec (Pr.01.25=2) and the
deceleration time from 50Hz to 0Hz is 10 seconds.
The rotation speed n = 120 X 50 /4 (rpm/min) = 25 rpm/sec

E.F. is external fault. It can be triggered by setting one of Pr.04.05~04.08 to 14. When the AC
motor drive receives the trigger, it will stop output immediately and display EF on the keypad.
The motor won’t run till the fault is cleared (enter “RESET).
The parameter determines how the motor is stopped when the AC motor drive receives a valid
stop command or detects External Fault.
Ramp:

the AC motor drive decelerates to Minimum Output Frequency (Pr.01.05)
according to the deceleration time(Pr.01.10 and Pr.01.12) and then stops.

Coast:

the AC motor drive stops the output instantly upon command, and the motor
free runs until it comes to a complete standstill.

The motor stop method is usually determined by the characteristics of the motor load and
how frequently it is stopped.
(1)

It is recommended to use “ramp to stop” for safety of personnel or to prevent
material from being wasted in applications where the motor has to stop after the
drive is stopped. The deceleration time has to be set accordingly.

(2)

If motor free running is allowed or the load inertia is large, it is recommended to
select “coast to stop”. For example: blowers, punching machines, centrifuges
and pumps.

Related parameters: Pr.01.10(Decel Time 1), Pr.01.12(Decel Time 2), Pr.04.05(Multi-function

From the table, we see that the PWM carrier frequency has a significant influence on the
electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise.
The PWM carrier frequency will be decreased automatically by heat sink temperature and
output current of the AC motor drive. It is used as a necessary precaution to prevent the AC
motor drive from overheating and thus extends IGBT’s life. If the user wants to fix carrier within
the rated range and won’t change by the change of the surrounding temperature and

Setting 1: to prevent the AC motor drive from overheating and thus extends IGBT’s life and
also prevent carrier change and motor noise due to surrounding temperature and frequently
load change, it needs to use this setting. Please refer to the following figure for the selection of
carrier frequency and rated current. For example, when carrier frequency should be kept in
15Hz, the rated current of the AC motor drive must be 65%. That means the rated current for
over load is 150% * 65% =97.5%. Thus, the rated current should be within the range of the

Chapter 4 Parameters|

When Pr.03.03 is set to 0, the analog output voltage is directly proportional to the output
frequency of the AC motor drive. With Pr.03.04 set to 100%, the Maximum Output Frequency
(Pr.01.00) of the AC motor drive corresponds to +10VDC on the AFM output.
Similarly, if Pr.03.03 is set to 1, the analog output voltage is directly proportional to the output
current of the AC drive. With Pr.03.04 set to 100%, then 2.5 times the rated current
corresponds to +10VDC on the AFM output.

NOTE
Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10V, Pr.
03.04 should be set using the following formula:
Pr. 03.04 = ((meter full scale voltage)/10) x 100%
For Example: When using the meter with full scale of 5 volts, adjust Pr.03.04 to 50%. If
Pr.03.03 is set to 0, then 5VDC will correspond to Maximum Output Frequency.

Example 7: Use of 0-10V potentiometer signal to run motor in FWD and REV direction
In this example, the input is programmed to run a motor in both forward and reverse direction. The
motor will be idle when the potentiometer position is at mid-point of its scale. Using the settings in this
example disables the external FWD and REV controls.

Example 8: Use negative slope
In this example, the use of negative slope is shown. Negative slopes are used in applications for
control of pressure, temperature or flow. The sensor that is connected to the input generates a large
signal (10V) at high pressure or flow. With negative slope settings, the AC motor drive will slow stop
the motor. With these settings the AC motor drive will always run in only one direction (reverse). This
can only be changed by exchanging 2 wires to the motor.

Please note the ACI/AVI switch on the AC motor drive. Switch to ACI for 4 to 20mA analog
current signal (ACI) (Pr.04.19 should be set to 0) and AVI for analog voltage signal (AVI2)
(Pr.04.19 should be set to 1). When ACi/AVI switch is not set by Pr.04.19, the keypad (optional)
will display fault code “AErr” and needs to press “RESET” to clear it.

Factory Setting: 1

This parameter is used to set the response time of digital input terminals MI1~MI6.
This parameter is to delay the signals on digital input terminals. 1 unit is 2 msec, 2 units are 4
msec, etc. The delay time is to debounce noisy signals that could cause the digital terminals to
malfunction.
The AC motor drive will check the status of multi-function input terminals every 2ms. It will only
confirm the command and change the status when the input terminals status is changed. Thus,
the delay time from command input to execution is 2msec+ (Pr.04.10+1) X 2ms. Suppose that
Pr.04.10 is set to 4, the delay time will be 12ms.

The Multi-function Input Terminals (refer to setting 1~4 of Pr.04.05 to 04.08) are used to select
one of the AC motor drive Multi-step speeds(max. 15 speeds). The speeds (frequencies) are
determined by Pr.05.00 to 05.14 as shown in the following.
The operation time of multi-step speeds can be set by PLC program.
The run/stop command can be controlled by the external terminal/digital
keypad/communication via Pr.02.01.
Each one of multi-step speeds can be set within 0.0~600.0Hz during operation.
These parameters can be applied in small machinery, food processing machinery, washing
equipment to control the operation procedure. It can be used instead of traditional circuit, such
as relay, switch or counter.

Factory Setting: 780.0

During deceleration, the DC bus voltage may exceed its Maximum Allowable Value due to
motor regeneration. When this function is enabled, the AC motor drive will not decelerate
further and keep the output frequency constant until the voltage drops below the preset value
again.
With moderate inertia load, over-voltage stall prevention will not occur and the real
deceleration time will be equal to the setting of deceleration time. The AC drive will
automatically extend the deceleration time with high inertia loads. If the deceleration time is
critical for the application, a brake resistor or brake unit should be used.
When the function of over-voltage stall prevention is activated, the deceleration time of the AC
motor drive will be larger than the setting.
When the deceleration time is obstruction in the application, it is not suitable to use this
function. The solution are:
1. moderate increase the deceleration time
2. used with a brake resistor (refer to appendix B for details) to consume the regenerative
energy by heat.

The over-current stall prevention during operation function is a protection. When the motor
runs with constant speed, the AC motor drive will decrease the output frequency automatically
when momentary overload.
If the output current exceeds the setting specified in Pr.06.02 when the drive is operating, the
drive will decrease its output frequency by Pr.01.10/Pr.01.12 to prevent the motor stall. If the
output current is lower than (Pr.06.02 setting –rated current X 5%), the drive will accelerate

Chapter 4 Parameters|

This function is used to protect the motor from overloading or overheating. When the motor
(self-cooled by fan) operates in low frequency, overload is seldom happened. Refer to the
following figure for the application.
When the rated current of motor is less than drive’s or bad design of the motor heat dissipation,
it can use this parameter to limit the output current of the AC motor drive to prevent motor from
overheating or damage.
Setting 0: the electronic thermal relay is used for standard motor(heatsink is fixed on rotor
shaft). When operating in low speed, the motor heat dissipation function will be bad. Thus, it
needs to decrease the action time of the electronic thermal relay to ensure the motor life.
Setting 1: the electron thermal relay is used for special motor(heatsink uses independent
power). The heat dissipation function has no direction relation with rotation speed. Thus, the
electronic thermal relay is still held in low speed to ensure the motor load ability in low speed.
In the frequent power ON/OFF applications, it can’t use this parameter (even set to 0 or 1) for
protection due to this function will be reset once the power is OFF. Thus, it needs to add the
thermal relay on each motor when an AC motor drive is connected with several motors.
Setting 0 or 1: when the electronic thermal relay protection is enabled in low speed operation,
the AC motor drive will display “OL1” and free run to stop. It needs to press “RESET” to clear
the warning message.

The parameter determines the time required for activating the I2t electronic thermal protection
function by the output frequency/current of the AC motor drive and operation time to prevent
motor from overheating.
The electronic thermal overload relay acts by Pr.06.06 setting:
1. Pr.06.06 is set to 0(Operate with a Standard Motor (self-cooled by fan)): when the output
current is greater than (Pr.07.00 Motor Rated Current (Motor 0)X (the corresponding motor
rated current % of motor rated frequency in standard motor figure in Pr.06.06) X150%), the AC
motor drive will start to count time. When accumulated time exceeds Pr.06.07(Electronic
Thermal Characteristic) setting, the electronic thermal overload relay protection (OL1) will be
ON.
2. Pr.06.06 is set to 1(Operate with a Special Motor (forced external cooling)): when the output
current is greater than (Pr.07.00 Motor Rated Current (Motor 0)X (the corresponding motor
rated current % of motor rated frequency in special motor figure in Pr.06.06) X150%), the AC
motor drive will start to count time. When accumulated time exceeds Pr.06.07(Electronic
Thermal Characteristic) setting, the electronic thermal overload relay protection (OL1) will be
ON.
The actual action time of electronic thermal characteristic will be adjusted by the output current
of the AC motor drive (motor load rate %). For large current, it needs short time to activate the
I2t electronic thermal protection function. For small current, it needs long time to activate the I2t
electronic thermal protection function as shown in the following figure.

Unit: A

30% FLA to 120% FLA

Use the following formula to calculate the percentage value entered in this parameter:
(Motor Current / AC Drive Current) x 100%
with Motor Current=Motor rated current in A on type shield
AC Drive Current=Rated current of AC drive in A (see Pr.00.01)
Pr.07.00 must be greater than Pr.07.01.
Example: Suppose that the rated current of 460V/2.0HP(1.5kW) is 4.2A with the factory setting
4.2A. The range that user can set is from 1.3A(4.2X30%) to 5.0A(4.2X120%). But when
Pr.07.00 is set to less than 1.7A(4.2X40%), it needs to set Pr.07.01 to be less than 30% FLA
first. In this way, Pr.07.00 is greater than Pr.07.01.
Pr.07.00 and Pr.07.01 must be set if the drive is programmed to operate in Vector Control
mode (Pr.00.10 = 1). They also must be set if the "Electronic Thermal Overload Relay"
(Pr.06.06) or "Slip Compensation"(Pr.07.03 and Pr.07.06) functions are selected.
The full-load current should be less than the rated current of the AC motor drive and should be
greater than 1/2 rated current of the AC motor drive.
Related parameters: Pr.00.01(Rated Current Display of the AC motor drive),
Pr.06.06(Electronic Thermal Overload Relay Selection), Pr.06.07(Electronic Thermal

Motor No-load Current (Motor 0)
Settings

This parameter is used to set the motor no-load current. The user must input motor no-load
current by the motor nameplate. The factory setting be set to 40% X the rated current of the
AC motor drive (refer to Pr.00.01 Rated Current Display of the AC motor drive).
Example: Suppose that the rated current of 460V/2.0hp(1.5kW) is 4.2A with factory setting
4.2A. The motor no-load current is 1.7A(4.2X40%) and it should set Pr.07.01 to 1.7.
This parameter must be set if the "Electronic Thermal Overload Relay" (Pr.06.06) or "Slip
Compensation"(Pr.07.03 and Pr.07.06) functions are selected.

Chapter 4 Parameters|

If the motor no-load current can’t be read from the nameplate, operating the AC motor drive
after unloading and read it from the digital keypad (optional, refer to Appendix B for details).
The setting value must be less than Pr.07.00 (Motor Rated Current).
Related parameters: Pr.00.01(Rated Current Display of the AC motor drive), Pr.07.00(Motor
Rated Current (Motor 0)), Pr.07.03(Slip Compensation (Used without PG) (Motor 0)) and
Pr.07.06(Motor Rated Slip (Motor 0))
07.02

Torque Compensation (Motor 0)
Settings

0.0 to 10.0

Factory Setting: 0.0

For the induction motor characteristic, parts of the drive output voltage will be absorbed by the
impedance of stator windings when motor load is large. In this circumstance, the output current
will be too large and output torque is insufficient due to the motor voltage at inductance end of
motor is insufficient and insufficient air-gap magnetic field. Using this parameter, it will auto
adjust output voltage by the load to get the best operation with the air-gap magnetic field is
held.
In V/f control mode, the voltage will decrease by the decreasing frequency. It will cause lower
torque in low speed due to less AC impedance and constant DC resistor. Thus, this parameter
can be set for the AC drive increase its voltage output to obtain a higher torque in low speed.
Too high torque compensation can overheat the motor.
This parameter is only used for V/f control mode.
Related parameters: Pr.00.10(Control Method) and Pr.07.08(Torque Compensation Time
Constant).
07.03

Slip Compensation (Used without PG) (Motor 0)
Settings

0.00 to 10.00

Factory Setting: 0.00

When the induction motor generates the electromagnetic torque, it needs the necessary slip.
But the slip can be ignored when it needs only 2-3% slip in higher speed. When the drive
operates, the slip and synchronous frequency are in reverse proportion. That is, the slip will be
increased with the decreasing synchronous frequency. The slip affects the motor speed
seriously in low speed because the motor may stop and can’t run with load when the
synchronous frequency is too low.
While driving an asynchronous motor, increasing the load on the AC motor drive will cause an

Chapter 4 Parameters|

This parameter may be used to compensate the slip by increasing the output frequency. When
the output current of the AC motor drive is bigger than the motor no-load current (Pr.07.01),
the AC drive will adjust its output frequency according to this parameter.
When Pr.00.10 is set from V/f mode to vector mode, this parameter will be set to 1.00
automatically. When Pr.00.10 is set from vector mode to V/f mode, this parameter will be set to
0.00. Please using this function after load is added and acceleration with gradual increasing
compensation. That is, add the output frequency with Pr.07.06(Motor Rated Slip (Motor 0)) X
Pr.07.03(Slip Compensation (Used without PG) (Motor 0)) on the output frequency

Auto Tuning R1 (motor doesn’t run)

Auto Tuning R1 + No-load Test (with running motor)

Start Auto Tuning by pressing RUN key after this parameter is set to 1 or 2.
When setting to 1, it will only auto detect R1 value and Pr.07.01 must be input manually. When
set to 2, the AC motor drive should be unloaded and the values of Pr.07.01 and Pr.07.05 will
be set automatically.
The steps for AUTO-Tuning are:
1.

Make sure that all the parameters are set to factory settings and the motor wiring is
correct.

Make sure the motor has no-load before executing auto-tuning and the shaft is not
connected to any belt or gear motor.

Fill in Pr.01.01, Pr.01.02, Pr.07.00, Pr.07.04 and Pr.07.06 with correct values.

After Pr.07.04 is set to 2, the AC motor drive will execute auto-tuning immediately after
receiving a ”RUN” command. (Note: The motor will run!). The total auto tune time will be
15 seconds + Pr.01.09 + Pr.01.10. Higher power drives need longer Accel/Decel time
(factory setting is recommended). After executing Auto-tune, Pr.07.04 is set to 0.

After executing, please check if there are values filled in Pr.07.01 and Pr.07.05. If not,
please press RUN key after setting Pr.07.04 again.

Then you can set Pr.00.10 to 1 and set other parameters according to your application
requirement.

Unit: Hz

Factory Setting: 3.00

It can be used to set the motor rated slip. Users need to input the actual rated rpm shown on
the nameplate of the motor.
Refer to the rated rpm and the number of poles on the nameplate of the motor and use the
following equation to calculate the rated slip.
Rated Slip (Hz) = Fbase (Pr.01.01 base frequency) – (rated rpm x motor pole/120)
Example: Assume that the rated frequency of the motor is 60Hz with 4 poles and the rated rpm
is 1650rpm. The rated slip calculated by the formula should be 60Hz-(1650X4/120)=5Hz.
This parameter has relation with Pr.07.03(Slip Compensation (Used without PG) (Motor 0)). To
get the best slip compensation effect, it needs to input the correct setting. The incorrect setting
may cause the invalid function and even damage the motor and drive.

Example: when Pr.07.06=5Hz and Pr.07.07=150%, the upper limit of the compensation
frequency is 7.5Hz. Therefore, for a 50Hz motor, the max. output is 57.5Hz.
If the motor speed is lower than the target speed and the speed isn’t changed after adjusting
Pr.07.03 setting, it may reach the upper limit of the compensation frequency and need to
increase Pr.07.07 setting.

When the motor is running at low frequency for a long time, the cooling function of the motor
fan will be lower. To prevent overheating, it needs to have a Positive Temperature Coefficient
thermoistor on the motor and connect its output signal to the drive’s corresponding control
terminals.
When the source of first/second frequency command is set to AVI (02.00=1/02.09=1), it will
disable the function of motor PTC overheat protection (i.e. Pr.07.12 cannot be set to 1). Only
one of the source of first master frequency command and second master frequency command
can be enable at one time.
If temperature exceeds the setting level, motor will be coast to stop and

displayed. When the temperature decreases below the level of (Pr.07.15-Pr.07.16) and
stops blinking, you can press RESET key to clear the fault.
Pr.07.14 (overheat protection level) must exceed Pr.07.15 (overheat warning level).
The PTC uses the AVI-input and is connected via resistor-divider as shown below.
The voltage between +10V to ACM: lies within 10.4V~11.2V.
The impedance for AVI is around 47kΩ.
Recommended value for resistor-divider R1 is 1~10kΩ.
Please contact your motor dealer for the curve of temperature and resistance value for PTC.

DC Brake Current Level
Settings

0 to 100%

Unit: %
Factory Setting: 0

This parameter sets the level of DC Brake Current output to the motor during start-up and
stopping. When setting DC Brake Current, the Rated Current (Pr.00.01) is regarded as 100%.
It is recommended to start with a low DC Brake Current Level and then increase until proper
holding torque has been achieved.
Related parameters: Pr.08.01(DC Brake Time during Start-up) and Pr.08.02(DC Brake Time
during Stopping)
08.01

DC Brake Time during Start-up
Settings

0.0 to 60.0 sec

Unit: second
Factory Setting: 0.0

The motor may keep running due to external factor or itself inertia. The over current may
damage the motor or activate the drive’s protection when running the drive suddenly. This
parameter can output a DC current with a torque to force the motor to stop for a stable start.
This parameter determines the duration of the DC Brake current after a RUN command. When
the time has elapsed, the AC motor drive will start accelerating from the Minimum Frequency
(Pr.01.05). The DC brake is invalid when Pr.08.01 is set to 0.
08.02

DC Brake Time during Stopping
Settings

0.0 to 60.0 sec

Unit: second
Factory Setting: 0.0

The motor may keep running due to external factor or itself inertia and can’t stop by
requirement. This parameter can output a DC current with a torque to force the motor to stop
after the drive stops outputting to ensure the motor is stop.
This parameter determines the duration of the DC Brake current during stopping. If stopping
with DC Brake is desired, Pr.02.02 Stop Method must be set to 0 or 2 for Ramp to Stop. The
DC brake is invalid when Pr.08.02 is set to 0.0.

DC Brake during Start-up is used for loads that may move before the AC drive starts, such as
fans and pumps. Under such circumstances, DC Brake can be used to hold the load in
position before setting it in motion.
DC Brake during stopping is used to shorten the stopping time and also to hold a stopped load
in position, such as cranes and cutting machines. For high inertia loads, a brake resistor for
dynamic brake may also be needed for fast decelerations. Refer to appendix B for the
information of brake resistors.

Operation stops (coast to stop) after momentary power loss.

Operation continues after momentary power loss, speed search
starts with the Last Frequency.

Operation continues after momentary power loss, speed search
starts with the minimum frequency.

This parameter determines the operation mode when the AC motor drive restarts from a
momentary power loss.
The power connected to the AC motor drive may be off temporarily with unknown factors. This
parameter can restart the drive after momentary power loss.
Setting 1: the drive will operate by the last frequency before momentary power loss. It will
accelerate to the master frequency after the drive output frequency and the motor rotor’s
speed are synchronous. It is recommended to use this setting for those motor loads which
have a large inertia and small resistance to save time by restarting without waiting the flywheel
stops completely, such as machinery equipment with a large-inertia flywheel.

Setting 2: the drive will operate by the min. frequency. It will accelerate to the master
frequency after the drive output frequency and motor rotor speed are synchronous. It is
recommended to use this setting for those motor loads which have a small inertia and large
resistance.
When using with PG card, the speed search will start with the actual motor speed detected by
the drive and accelerate to the setting frequency (setting 1 and 2 are invalid at this moment).

If the duration of a power loss is less than this parameter setting, the AC motor drive will act by
Pr.08.04 setting. If it exceeds the Maximum Allowable Power Loss Time, the AC motor drive
output is then turned off (coast stop).
The selected operation after power loss in Pr.08.04 is only executed when the maximum
allowable power loss time is ≤20 seconds and the AC motor drive displays “Lu”.
But if the AC motor drive is powered off due to overload, even if the maximum allowable power
loss time is ≤20 seconds, the operation mode as set in Pr.08.04 is not executed. In that case it
starts up normally.

The speed search actions between Pr.08.04 and Pr.08.06 are the same.
The priority of Pr.08.06 is higher than Pr.08.04. That is, Pr.08.04 will be invalid after Pr.08.06 is
set and the speed search will act by Pr.08.06.

When momentary power loss is detected, the AC motor drive will block its output and then wait
for a specified period of time (determined by Pr.08.07, called Base-Block Time) before
resuming operation. This parameter should be set at a value to ensure that any residual
regeneration voltage from the motor on the output has disappeared before the drive is
activated again.
This parameter also determines the waiting time before resuming operation after External
Baseblock and Auto Restart after Fault (Pr.08.15).
When using a PG card with PG (encoder), speed search will begin at the actual PG (encoder)
feedback speed.

It limits the drive output current during speed search.
When executing speed search, the V/f curve will be by the setting in the group 01.
The level of speed search will affect the speed synchronization time. The larger setting is set
and the faster it will reach the speed synchronization. But too large setting may cause overload.
When Pr.08.04 is set to 1: When the speed searches downward, the output frequency starts
with the master frequency. The output voltage and output current will be increased from 0.
When the output current reaches Pr.08.08 setting, the output frequency continuous searches
downward. When the output frequency, output voltage and V/f setting frequency are the same,
it will be regarded as the synchronization reached and accelerate to the master frequency by
V/f curve.
When Pr.08.04 is set to 2: When the speed searches upward, it will accelerate by V/f curve.

08.16

Auto Reset Time at Restart after Fault
Settings

Unit: second

0.1 to 6000 sec

Factory Setting: 60.0

This parameter is used to set the auto reset time at restart after fault. After restarting for fault, if
there is no fault for over Pr.08.16 setting from the restart for the previous fault, the auto reset
times for restart after fault will be reset to Pr.08.15 setting..
This parameter should be used in conjunction with Pr.08.15.
For example: If Pr.08.15 is set to 10 and Pr.08.16 is set to 600s (10 min), and if there is no
fault for over 600 seconds from the restart for the previous fault, the auto reset times for restart
after fault will be reset to 10.

When Pr.08.17 is set to 1, the acceleration and deceleration will operate with full voltage.
During constant speed operation, it will auto calculate the best voltage value by the load power
for the load. This function is not suitable for the ever-changing load or near full-load during
operation.
The max. energy saving is in the stable load output. At this moment, the output voltage is
almost 70% of the rated voltage.

Automatic Voltage Regulation (AVR)
Factory Setting: 0
Settings

AVR function enabled

AVR function disabled

AVR function disabled for deceleration

AVR function disabled for stop

The rated voltage of the motor is usually 230V/200VAC 50Hz/60Hz and the input voltage of
the AC motor drive may vary between 180V to 264 VAC 50Hz/60Hz. Therefore, when the AC
motor drive is used without AVR function, the output voltage will be the same as the input
voltage. When the motor runs at voltages exceeding the rated voltage with 12% - 20%, its
lifetime will be shorter and it can be damaged due to higher temperature, failing insulation and
unstable torque output.
AVR function automatically regulates the AC motor drive output voltage to the Maximum
Output Voltage (Pr.01.02). For instance, if Pr.01.02 is set at 200 VAC and the input voltage is
at 200V to 264VAC, then the Maximum Output Voltage will automatically be reduced to a
maximum of 200VAC.
Setting 0: when AVR function is enabled, the drive will calculate the output voltage by actual
DC-bus voltage. The output voltage won’t be changed by DC bus voltage.
Setting 1: when AVR function is disabled, the drive will calculate the output voltage by DC-bus
voltage. The output voltage will be changed by DC bus voltage. It may cause insufficient/over
current.
Setting 2: the drive will disable the AVR during deceleration, such as operated from high speed
to low speed.
Setting 3: the drive will disable the AVR function at stop to accelerate the brake.
When the motor ramps to stop, the deceleration time is longer. When setting this parameter to
2 with auto acceleration/deceleration, the deceleration will be quicker.
Related parameter: Pr.01.16(Auto acceleration / deceleration (refer to Accel/Decel time
setting))

Chapter 4 Parameters|

This parameter sets the DC-bus voltage at which the brake chopper is activated. Users can
choose the suitable brake resistor to have the best deceleration. Refer to appendix B for the
information of the brake resistor.
This parameter will be invalid for Frame A models (VFD002E11A/21A/23A,
VFD004E11A/21A/23A/43A, VFD007E21A/23A/43A and VFD022E23A/43A) without brake

Compensation Coefficient for Motor Instability
Settings

0.0~5.0

Factory Setting: 0.0

In V/f control mode, the drift current may cause slight motor vibration in the slip compensation
or torque compensation. It can be ignored if this slight vibration doesn’t affect the application.
The drift current will occur in a specific zone of the motor and it will cause serious motor
vibration. It is recommended to use this parameter(the recommended value is 2.0) to improve
this situation greatly.
The drift current zone of the high-power motors is usually in the low frequency area.
It is recommended to set to more than 2.0.

The OOB (Out Of Balance Detection) function can be used with PLC for washing machine.
When multi-function input terminal is enabled (MI=26), it will get Δθ value from the settings of
Pr.08.21 and Pr.08.22. PLC or the host controller will decide the motor speed by this t Δθ
value (Pr.08.23). When Δθ value is large, it means unbalanced load. At this moment, it needs
to lower the frequency command by PLC or the host controller. On the other hand, it can be
high-speed operation.

This parameter is used for starting and stopping a motor with high inertia. A motor with high
inertia will take a long time to stop completely. By setting this parameter, the user does not
need to wait for the motor to come to a complete stop before restarting the AC motor drive. If a
PG card and encoder is used on the drive and motor, then the speed search will start from the
speed that is detected by the encoder and accelerate quickly to the setting frequency.
When using this parameter with PG feedback control, this function will be enabled as Pr.13.00
and Pr.13.01 are set. It has no relation with Pr.00.10. Pr.08-04 and Pr.08-06 will be disabled
when using this parameter with PG feedback control.
Please make sure Pr.13.00 to Pr.13.02 are set correctly. An incorrect setting may cause the
motor to exceed its speed limit and permanent damage to the motor and machine can occur.

CRC (Cyclical Redundancy Check) is calculated by the following steps:
Step 1: Load a 16-bit register (called CRC register) with FFFFH.
Step 2: Exclusive OR the first 8-bit byte of the command message with the low order byte of
the 16-bit CRC register, putting the result in the CRC register.
Step 3: Examine the LSB of CRC register.
Step 4: If the LSB of CRC register is 0, shift the CRC register one bit to the right with MSB
zero filling, then repeat step 3. If the LSB of CRC register is 1, shift the CRC register one bit
to the right with MSB zero filling, Exclusive OR the CRC register with the polynomial value
A001H, then repeat step 3.
Step 5: Repeat step 3 and 4 until eight shifts have been performed. When this is done, a
complete 8-bit byte will have been processed.
Step 6: Repeat step 2 to 5 for the next 8-bit byte of the command message. Continue doing
this until all bytes have been processed. The final contents of the CRC register are the CRC
value. When transmitting the CRC value in the message, the upper and lower bytes of the
CRC value must be swapped, i.e. the lower order byte will be transmitted first.
The following is an example of CRC generation using C language. The function takes two
arguments:
Unsigned char* data Å a pointer to the message buffer
Unsigned char length Å the quantity of bytes in the message buffer
The function returns the CRC value as a type of unsigned integer.
Unsigned int crc_chk(unsigned char* data, unsigned char length){
int j;
unsigned int reg_crc=0xFFFF;
while(length--){
reg_crc ^= *data++;
for(j=0;j<8;j++){
if(reg_crc & 0x01){ /* LSB(b0)=1 */
reg_crc=(reg_crc>>1) ^ 0xA001;

3.6 Exception response:
The AC motor drive is expected to return a normal response after receiving command
messages from the master device. The following depicts the conditions when no normal
response is replied to the master device.
The AC motor drive does not receive the messages due to a communication error; thus, the
AC motor drive has no response. The master device will eventually process a timeout
condition.
The AC motor drive receives the messages without a communication error, but cannot
handle them. An exception response will be returned to the master device and an error
message “CExx” will be displayed on the keypad of AC motor drive. The xx of “CExx” is a
decimal code equal to the exception code that is described below.
In the exception response, the most significant bit of the original command code is set to 1,
and an exception code which explains the condition that caused the exception is returned.

Group 10: PID Control
A. Common applications for PID control
1. Flow control: A flow sensor is used to feedback the flow data and perform accurate flow control.
2. Pressure control: A pressure sensor is used to feedback the pressure data and perform precise
pressure control.
3. Air volume control: An air volume sensor is used to feedback the air volume data to have excellent
air volume regulation.
4. Temperature control: A thermocouple or thermistor is used to feedback temperature data for
comfortable temperature control.
5. Speed control: A speed sensor or encoder is used to feedback motor shaft speed or input another
machines speed as a target value for closed loop speed control of master-slave operation.
Pr.10.00 sets the PID setpoint source (target value). PID control operates with the feedback signal as
set by Pr.10.01 either 0~+10V voltage or 4-20mA current.

C. Concept of PID control
1. Proportional gain(P): the output is proportional to input. With only proportional gain control, there
will always be a steady-state error.
2. Integral time(I): the controller output is proportional to the integral of the controller input. To
eliminate the steady-state error, an “integral part” needs to be added to the controller. The integral
time decides the relation between integral part and error. The integral part will be increased by time
even if the error is small. It gradually increases the controller output to eliminate the error until it is 0.
In this way a system can be stable without steady-state error by proportional gain control and integral
time control.

4-157

Chapter 4 Parameters|

3. Differential control(D): the controller output is proportional to the differential of the controller input.
During elimination of the error, oscillation or instability may occur. The differential control can be used
to suppress these effects by acting before the error. That is, when the error is near 0, the differential
control should be 0. Proportional gain(P) + differential control(D) can be used to improve the system
state during PID adjustment.

D. When PID control is used in a constant pressure pump feedback application:
Set the application’s constant pressure value (bar) to be the setpoint of PID control. The pressure
sensor will send the actual value as PID feedback value. After comparing the PID setpoint and PID
feedback, there will be an error. Thus, the PID controller needs to calculate the output by using
proportional gain(P), integral time(I) and differential time(D) to control the pump. It controls the drive
to have different pump speed and achieves constant pressure control by using a 4-20mA signal
corresponding to 0-10 bar as feedback to the drive.

set in Pr.10.02, the faster response it will get. The smaller value is set in Pr.10.02, the slower

The integral controller is used to eliminate the error during stable system. The integral control
doesn’t stop working until error is 0. The integral is acted by the integral time. The smaller
integral time is set, the stronger integral action will be. It is helpful to reduce overshoot and
oscillation to make a stable system. At this moment, the decreasing error will be slow. The
integral control is often used with other two controls to become PI controller or PID controller.
This parameter is used to set the integral time of I controller. When the integral time is long, it
will have small gain of I controller, the slower response and bad external control. When the

The differential controller is used to show the change of system error and it is helpful to
preview the change of error. So the differential controller can be used to eliminate the error to
improve system state. With the suitable differential time, it can reduce overshoot and shorten
adjustment time. However, the differential operation will increase the noise interference.
Please note that too large differential will cause big noise interference. Besides, the differential
shows the change and the output of the differential will be 0 when there is no change.
Therefore, the differential control can’t be used independently. It needs to be used with other
two controllers to make a PD controller or PID controller.
This parameter can be used to set the gain of D controller to decide the response of error
change. The suitable differential time can reduce the overshoot of P and I controller to
decrease the oscillation and have a stable system. But too long differential time may cause
system oscillation.
The differential controller acts for the change of error and can’t reduce the interference. It is
not recommended to use this function in the serious interference.

This parameter defines an upper bound or limit for the integral gain (I) and therefore limits the
Master Frequency. The formula is: Integral upper bound = Maximum Output Frequency

Too large integral value will make the slow response due to sudden load change. In this way, it
may cause motor stall or machine damage.

It is used to set the time that required for the low-pass filter of PID output. Increasing the
setting, it may affect the drive’s response speed.
The frequency output of PID controller will filter after primary delay filter time. It can smooth the
change of the frequency output. The longer primary delay filter time is set, the slower response
time it will be.
The unsuitable primary delay filter time may cause system oscillation.
PID control can be used for speed, pressure and flow control. It needs to use with the relevant

Group 13: PG function Parameters for Extension Card
Pulse generator card (PG card) is mainly applied in the detection components of speed control or
position control. It usually makes a closed-loop speed control system with encoder. The AC motor
drive is used with encoder and PG card to have a complete speed control and position detection
system.
Please make sure that the extension card is installed on the AC motor drive correctly before using
group 12 parameters. See Appendix B for details.

Single phase

Forward/Counterclockwise rotation

Reverse/Clockwise rotation

There are two outputs, 1-phase and 2-phase output, for the encoder output. For the 1-phase
output, the encoder output is a group of pulse signal. For the 2-phase output, the encoder can
output A and B pulse signals with 90o phase difference. The encoder is defined by the timing
of A and B pulses as the following figure. It can not only measure the speed but distinguish
motor rotation direction by A and B pulse signals.
PG card receives A and B pulses from encoder output and sends this feedback signal to the
AC motor drive for speed or position control.
Setting 0: disable PG function.
Setting 1: for speed/position control but can’t distinguish motor rotation direction.
Setting 2: both for speed control and distinguish motor rotation direction. A phase leads B
phase as shown in the following diagram and motor is forward running.
Setting 3: both for speed control and distinguish motor rotation direction. B phase leads A

5.13 Electromagnetic/Induction Noise
Many sources of noise surround AC motor drives and penetrate it by radiation or conduction. It may
cause malfunctioning of the control circuits and even damage the AC motor drive. Of course, there
are solutions to increase the noise tolerance of an AC motor drive. But this has its limits. Therefore,
solving it from the outside as follows will be the best.
1.
2.

Add surge suppressor on the relays and contacts to suppress switching surges.
Shorten the wiring length of the control circuit or serial communication and keep them
separated from the power circuit wiring.

Comply with the wiring regulations by using shielded wires and isolation amplifiers for
long length.

The grounding terminal should comply with the local regulations and be grounded
independently, i.e. not to have common ground with electric welding machines and other
power equipment.

Connect a noise filter at the mains input terminal of the AC motor drive to filter noise from
the power circuit.

In short, solutions for electromagnetic noise exist of “no product”(disconnect disturbing equipment),
“no spread”(limit emission for disturbing equipment) and “no receive”(enhance immunity).

5.14 Environmental Condition
Since the AC motor drive is an electronic device, you should comply with the environmental
conditions. Here are some remedial measures if necessary.
1.

To prevent vibration, the use of anti-vibration dampers is the last choice. Vibrations must
be within the specification. Vibration causes mechanical stress and it should not occur
frequently, continuously or repeatedly to prevent damage to the AC motor drive.

Store the AC motor drive in a clean and dry location, free from corrosive fumes/dust to
prevent corrosion and poor contacts. Poor insulation in a humid location can cause shortcircuits. If necessary, install the AC motor drive in a dust-proof and painted enclosure and
in particular situations, use a completely sealed enclosure.

The ambient temperature should be within the specification. Too high or too low
temperature will affect the lifetime and reliability. For semiconductor components, damage
will occur once any specification is out of range. Therefore, it is necessary to periodically
check air quality and the cooling fan and provide extra cooling of necessary. In addition,
the microcomputer may not work in extremely low temperatures, making cabinet heating
necessary.

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

5-9

Chapter 5 Troubleshooting|

Store within a relative humidity range of 0% to 90% and non-condensing environment.
Use an air conditioner and/or exsiccator.

5.15 Affecting Other Machines
An AC motor drive may affect the operation of other machines due to many reasons. Some solutions
are:

High Harmonics at Power Side
High harmonics at power side during running can be improved by:

Separate the power system: use a transformer for AC motor drive.

Use a reactor at the power input terminal of the AC motor drive.

If phase lead capacitors are used (never on the AC motor drive output!!), use serial
reactors to prevent damage to the capacitors damage from high harmonics.

serial reactor

phase lead capacitor

Motor Temperature Rises
When the motor is a standard induction motor with fan, the cooling will be bad at low speeds,
causing the motor to overheat. Besides, high harmonics at the output increases copper and
core losses. The following measures should be used depending on load and operation
range.

Use a motor with independent ventilation (forced external cooling) or increase the motor
rated power.

5-10

Use a special inverter duty motor.

Do NOT run at low speeds for long time.

Chapter 6 Fault Code Information and Maintenance

6.1 Fault Code Information
The AC motor drive has a comprehensive fault diagnostic system that includes several different
alarms and fault messages. Once a fault is detected, the corresponding protective functions will be
activated. The following faults are displayed as shown on the AC motor drive digital keypad display.
The five most recent faults can be read from the digital keypad or communication.

NOTE
Wait 5 seconds after a fault has been cleared before performing reset via keypad of input terminal.

Check if motor power corresponds with the
AC motor drive output power.
Check the wiring connections to U/T1, V/T2,
W/T3 for possible short circuits.
Check the wiring connections between the AC
motor drive and motor for possible short
circuits, also to ground.
Check for loose contacts between AC motor
drive and motor.
Increase the Acceleration Time.
Check for possible excessive loading
conditions at the motor.
If there are still any abnormal conditions when
operating the AC motor drive after a shortcircuit is removed and the other points above
are checked, it should be sent back to
manufacturer.
Check if the input voltage falls within the
rated AC motor drive input voltage range.
Check for possible voltage transients.
DC-bus over-voltage may also be caused by
motor regeneration. Either increase the
Decel. Time or add an optional brake resistor
(and brake unit).
Check whether the required brake power is
within the specified limits.

6.1.2 Reset
There are three methods to reset the AC motor drive after solving the fault:
1.
2.

Press

key on keypad.

Set external terminal to “RESET” (set one of Pr.04.05~Pr.04.08 to 05) and then set to be
ON.

Send “RESET” command by communication.

NOTE
Make sure that RUN command or signal is OFF before executing RESET to prevent damage or
personal injury due to immediate operation.

6.2 Maintenance and Inspections
Modern AC motor drives are based on solid-state electronics technology. Preventive maintenance is
required to keep the AC motor drive in its optimal condition, and to ensure a long life. It is
recommended to have a qualified technician perform a check-up of the AC motor drive regularly.

Daily Inspection:
Basic check-up items to detect if there were any abnormalities during operation are:
1.

Whether the motors are operating as expected.

Whether the installation environment is abnormal.

Whether the cooling system is operating as expected.

Whether any irregular vibration or sound occurred during operation.

Whether the motors are overheating during operation.

Always check the input voltage of the AC drive with a Voltmeter.

Periodic Inspection:
Before the check-up, always turn off the AC input power and remove the cover. Wait at least 10
minutes after all display lamps have gone out, and then confirm that the capacitors have fully
discharged by measuring the voltage between

6-6

. It should be less than 25VDC.

NOTE
1.

Please select the brake unit and/or brake resistor according to the table. “-“ means no
Delta product. Please use the brake unit according to the Equivalent Resistor Value.

If damage to the drive or other equipment is due to the fact that the brake resistors and
the brake modules in use are not provided by Delta, the warranty will be void.

3.
4.

Take into consideration the safety of the environment when installing the brake resistors.
If the minimum resistance value is to be utilized, consult local dealers for the calculation of
the power in Watt.

Please select thermal relay trip contact to prevent resistor over load. Use the contact to
switch power off to the AC motor drive!

When using more than 2 brake units, equivalent resistor value of parallel brake unit can’t
be less than the value in the column “Minimum Equivalent Resistor Value for Each AC
Drive” (the right-most column in the table).

Please read the wiring information in the user manual of the brake unit thoroughly prior to
installation and operation.

When using with the brake resistor or brake unit, it needs to disable over-voltage stall
prevention function (set Pr.06.00 to 0). It is recommended to disable AVR (auto voltage
regulation) function (set Pr.08.18 to 1).

Definition for Brake Usage ED%
Explanation: The definition of the barking usage ED(%) is for assurance of enough time
for the brake unit and brake resistor to dissipate away heat generated by braking. When
the brake resistor heats up, the resistance would increase with temperature, and brake
torque would decrease accordingly. Suggested cycle time is one minute
100%

Brake Time

Cycle Time

10.

ED% = T1/T0x100(%)
T0

For safety reasons, install a thermal overload relay between brake unit and brake resistor.
Together with the magnetic contactor (MC) in the mains supply circuit to the drive it offers
protection in case of any malfunctioning. The purpose of installing the thermal overload
relay is to protect the brake resistor against damage due to frequent brake or in case the
brake unit is continuously on due to unusual high input voltage. Under these
circumstances the thermal overload relay switches off the power to the drive. Never let
the thermal overload relay switch off only the brake resistor as this will cause serious
damage to the AC Motor Drive.

Question

Used to improve the input power factor, to
reduce harmonics and provide protection from
AC line disturbances. (surges, switching
spikes, short interruptions, etc.). The AC line
reactor should be installed when the power
supply capacity is 500kVA or more and
exceeds 6 times the inverter capacity, or the
mains wiring distance ≤ 10m.

When the mains power capacity is too large,
line impedance will be small and the charge
current will be too high. This may damage AC
motor drive due to higher rectifier
temperature.

Installation
All electrical equipment, including AC motor drives, will generate high-frequency/low-frequency noise
and will interfere with peripheral equipment by radiation or conduction when in operation. By using an
EMI filter with correct installation, much interference can be eliminated. It is recommended to use
DELTA EMI filter to have the best interference elimination performance.
We assure that it can comply with following rules when AC motor drive and EMI filter are installed
and wired according to user manual:
EN61000-6-4
EN61800-3: 1996
EN55011 (1991) Class A Group 1
General precaution
1.
2.

EMI filter and AC motor drive should be installed on the same metal plate.
Please install AC motor drive on footprint EMI filter or install EMI filter as close as possible to
the AC motor drive.

Please wire as short as possible.

Metal plate should be grounded.

The cover of EMI filter and AC motor drive or grounding should be fixed on the metal plate and
the contact area should be as large as possible.

Choose suitable motor cable and precautions
Improper installation and choice of motor cable will affect the performance of EMI filter. Be sure to
observe the following precautions when selecting motor cable.
1.

Use the cable with shielding (double shielding is the best).

The shielding on both ends of the motor cable should be grounded with the minimum length
and maximum contact area.

Remove any paint on metal saddle for good ground contact with the plate and shielding.

The length of motor cable
When motor is driven by an AC motor drive of PWM type, the motor terminals will experience surge
voltages easily due to components conversion of AC motor drive and cable capacitance. When the
motor cable is very long (especially for the 460V series), surge voltages may reduce insulation
quality. To prevent this situation, please follow the rules below:
Use a motor with enhanced insulation.
Connect an output reactor (optional) to the output terminals of the AC motor drive
The length of the cable between AC motor drive and motor should be as short as possible
(10 to 20 m or less)

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

NOTE

Appendix B Accessories|

When a thermal O/L relay protected by motor is used between AC motor drive and motor, it may
malfunction (especially for 460V series), even if the length of motor cable is only 165 ft (50m) or less.
To prevent it, please use AC reactor and/or lower the carrier frequency (Pr. 02.03 PWM carrier
frequency).

NOTE
Never connect phase lead capacitors or surge absorbers to the output terminals of the AC motor
drive.
If the length is too long, the stray capacitance between cables will increase and may cause
leakage current. It will activate the protection of over current, increase leakage current or not
insure the correction of current display. The worst case is that AC motor drive may damage.
If more than one motor is connected to the AC motor drive, the total wiring length is the sum
of the wiring length from AC motor drive to each motor.

Appendix C How to Select the Right AC Motor Drive
The choice of the right AC motor drive for the application is very important and has great influence
on its lifetime. If the capacity of AC motor drive is too large, it cannot offer complete protection to the
motor and motor maybe damaged. If the capacity of AC motor drive is too small, it cannot offer the
required performance and the AC motor drive maybe damaged due to overloading.
But by simply selecting the AC motor drive of the same capacity as the motor, user application
requirements cannot be met completely. Therefore, a designer should consider all the conditions,
including load type, load speed, load characteristic, operation method, rated output, rated speed,
power and the change of load capacity. The following table lists the factors you need to consider,
depending on your requirements.

Appendix C How to Select the Right AC Motor Drive|

C.2 General Precaution
Selection Note
1.

When the AC Motor Drive is connected directly to a large-capacity power transformer
(600kVA or above) or when a phase lead capacitor is switched, excess peak currents
may occur in the power input circuit and the converter section may be damaged. To avoid
this, use an AC input reactor (optional) before AC Motor Drive mains input to reduce the
current and improve the input power efficiency.

When a special motor is used or more than one motor is driven in parallel with a single
AC Motor Drive, select the AC Motor Drive current ≥1.25x(Sum of the motor rated
currents).

The starting and accel./decel. characteristics of a motor are limited by the rated current
and the overload protection of the AC Motor Drive. Compared to running the motor D.O.L.
(Direct On-Line), a lower starting torque output with AC Motor Drive can be expected. If
higher starting torque is required (such as for elevators, mixers, tooling machines, etc.)
use an AC Motor Drive of higher capacity or increase the capacities for both the motor
and the AC Motor Drive.

When an error occurs on the drive, a protective circuit will be activated and the AC Motor
Drive output is turned off. Then the motor will coast to stop. For an emergency stop, an
external mechanical brake is needed to quickly stop the motor.

Parameter Settings Note
1.

The AC Motor Drive can be driven at an output frequency up to 400Hz (less for some
models) with the digital keypad. Setting errors may create a dangerous situation. For
safety, the use of the upper limit frequency function is strongly recommended.

High DC brake operating voltages and long operation time (at low frequencies) may
cause overheating of the motor. In that case, forced external motor cooling is
recommended.

3.
4.

Motor accel./decel. time is determined by motor rated torque, load torque, and load inertia.
If the stall prevention function is activated, the accel./decel. time is automatically extended
to a length that the AC Motor Drive can handle. If the motor needs to decelerate within a
certain time with high load inertia that can’t be handled by the AC Motor Drive in the

C-4

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

Appendix C How to Select the Right AC Motor Drive|

required time, either use an external brake resistor and/or brake unit, depending on the
model, (to shorten deceleration time only) or increase the capacity for both the motor and
the AC Motor Drive.

C.3 How to Choose a Suitable Motor
Standard motor
When using the AC Motor Drive to operate a standard 3-phase induction motor, take the
following precautions:
1.
2.

The energy loss is greater than for an inverter duty motor.
Avoid running motor at low speed for a long time. Under this condition, the motor
temperature may rise above the motor rating due to limited airflow produced by the
motor’s fan. Consider external forced motor cooling.

When the standard motor operates at low speed for long time, the output load must be
decreased.

The load tolerance of a standard motor is as follows:

Frequency (Hz)

If 100% continuous torque is required at low speed, it may be necessary to use a special
inverter duty motor.

Motor dynamic balance and rotor endurance should be considered once the operating
speed exceeds the rated speed (60Hz) of a standard motor.

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

C-5

Appendix C How to Select the Right AC Motor Drive|

Motor torque characteristics vary when an AC Motor Drive instead of commercial power
supply drives the motor. Check the load torque characteristics of the machine to be
connected.

Because of the high carrier frequency PWM control of the VFD series, pay attention to the
following motor vibration problems:

Resonant mechanical vibration: anti-vibration (damping) rubbers should be used to mount

Motor imbalance: special care is required for operation at 50 or 60 Hz and higher

To avoid resonances, use the Skip frequencies.

frequency.

The motor fan will be very noisy when the motor speed exceeds 50 or 60Hz.

Special motors:
1.

Pole-changing (Dahlander) motor:
The rated current is differs from that of a standard motor. Please check before operation
and select the capacity of the AC motor drive carefully. When changing the pole number
the motor needs to be stopped first. If over current occurs during operation or
regenerative voltage is too high, please let the motor free run to stop (coast).

Submersible motor:
The rated current is higher than that of a standard motor. Please check before operation
and choose the capacity of the AC motor drive carefully. With long motor cable between
AC motor drive and motor, available motor torque is reduced.

Explosion-proof (Ex) motor:
Needs to be installed in a safe place and the wiring should comply with the (Ex)
requirements. Delta AC Motor Drives are not suitable for (Ex) areas with special
precautions.

Gear reduction motor:
The lubricating method of reduction gearbox and speed range for continuous operation
will be different and depending on brand. The lubricating function for operating long time
at low speed and for high-speed operation needs to be considered carefully.

Synchronous motor:
The rated current and starting current are higher than for standard motors. Please check
before operation and choose the capacity of the AC motor drive carefully. When the AC

motor drive operates more than one motor, please pay attention to starting and changing
the motor.
Power Transmission Mechanism
Pay attention to reduced lubrication when operating gear reduction motors, gearboxes, belts
and chains, etc. over longer periods at low speeds. At high speeds of 50/60Hz and above,
lifetime reducing noises and vibrations may occur.

D.3.2 Introduction
Ladder diagram is a diagram language that applied on the automatic control and it is also a
diagram that made up of the symbols of electric control circuit. PLC procedures are finished
after ladder diagram editor edits the ladder diagram. It is easy to understand the control flow
that indicated with diagram and also accept by technical staff of electric control circuit. Many
basic symbols and motions of ladder diagram are the same as mechanical and electrical
equipments of traditional automatic power panel, such as button, switch, relay, timer,
counter and etc.
The kinds and amounts of PLC internal equipment will be different with brands. Although
internal equipment has the name of traditional electric control circuit, such as relay, coil and
contact. It doesn’t have the real components in it. In PLC, it just has a basic unit of internal
memory. If this bit is 1, it means the coil is ON and if this bit is 0, it means the coil is OFF.
You should read the corresponding value of that bit when using contact (Normally Open, NO
or contact a). Otherwise, you should read the opposite sate of corresponding value of that
bit when using contact (Normally Closed, NC or contact b). Many relays will need many bits,
such as 8-bits makes up a byte. 2 bytes can make up a word. 2 words makes up double
word. When using many relays to do calculation, such as add/subtraction or shift, you could

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

D-7

Appendix D How to Use PLC Function|

use byte, word or double word. Furthermore, the two equipments, timer and counter, in PLC
not only have coil but also value of counting time and times.
In conclusion, each internal storage unit occupies fixed storage unit. When using these
equipments, the corresponding content will be read by bit, byte or word.
Basic introduction of the inner equipment of PLC:
Input relay

Input relay is the basic storage unit of internal memory that corresponds to
external input point (it is the terminal that used to connect to external input switch
and receive external input signal). Input signal from external will decide it to
display 0 or 1. You couldn’t change the state of input relay by program design or
forced ON/OFF via WPLSoft. The contacts (contact a, b) can be used unlimitedly.
If there is no input signal, the corresponding input relay could be empty and can’t
be used with other functions.
Equipment indication method: X0, X1,…X7, X10, X11,…. The symbol of
equipment is X and the number uses octal.

Output relay Output relay is the basic storage unit of internal memory that corresponds to
external output point (it is used to connect to external load). It can be driven by
input relay contact, the contact of other internal equipment and itself contact. It
uses a normally open contact to connect to external load and other contacts can
be used unlimitedly as input contacts. It doesn’t have the corresponding output
relay, if need, it can be used as internal relay.
Equipment indication: Y0, Y1,…Y7, Y10, Y11,…. . The symbol of
equipment is Y and the number uses octal.
Internal relay The internal relay doesn’t connect directly to outside. It is an auxiliary relay in
PLC. Its function is the same as the auxiliary relay in electric control circuit. Each
auxiliary relay has the corresponding basic unit. It can be driven by the contact of
input relay, output relay or other internal equipment. Its contacts can be used
unlimitedly. Internal auxiliary relay can’t output directly, it should output with
output point.
Equipment indication: M0, M1,…, M4, M159. The symbol of equipment
is M and the number uses decimal number system.
Timer

Timer is used to control time. There are coil, contact and timer storage. When coil
is ON, its contact will act (contact a is close, contact b is open) when attaining
desired time. The time value of timer is set by settings and each timer has its
regular period. User sets the timer value and each timer has its timing period.
Once the coil is OFF, the contact won’t act (contact a is open and contact b is
close) and the timer will be set to zero.
Equipment indication: T0, T1,…,T15. The symbol of equipment is T and
the number uses decimal system. The different number range
corresponds with the different timing period.

Counter

Counter is used to count. It needs to set counter before using counter (i.e. the
pulse of counter). There are coil, contacts and storage unit of counter in counter.
When coil is from OFF to ON, that means input a pulse in counter and the counter
should add 1. There are 16-bit, 32-bit and high-speed counter for user to use.
Equipment indication: C0, C1,…,C7. The symbol of equipment is C and
the number uses decimal.

Data register PLC needs to handle data and operation when controlling each order, timer value
and counter value. The data register is used to store data or parameters. It stores
D-8

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

Appendix D How to Use PLC Function|

16-bit binary number, i.e. a word, in each register. It uses two continuous number
of data register to store double words.
Equipment indication: D0, D1,…,D29. The symbol of equipment is D and
the number uses decimal.

The program edited method is from left power line to right power line. (the right power line
will be omitted during the edited of WPLSoft.) After editing a row, go to editing the next row.
The maximum contacts in a row are 11 contacts. If you need more than 11 contacts, you
could have the new row and start with continuous line to continue more input devices. The
continuous number will be produced automatically and the same input point can be used
repeatedly. The drawing is shown as follows.

MPS, MRD, MPP commands: Divergent memory of multi-output. It can produce many
various outputs.

The command MPS is the start of divergent point. The divergent point means the
connection place between horizontal line and vertical line. We should determine to have
contact memory command or not according to the contacts status in the same vertical line.
Basically, each contact could have memory command but in some places of ladder
diagram conversion will be omitted due to the PLC operation convenience and capacity
limit. MPS command can be used for 8 continuous times and you can recognize this
command by the symbol “┬”.

MRD command is used to read memory of divergent point. Because the logical status is
the same in the same horizontal line, it needs to read the status of original contact to keep

on analyzing other ladder diagram. You can recognize the command MRD by the symbol

MPP command is used to read the start status of the top level and pop it out from stack.
Because it is the last item of the horizontal line, it means the status of this horizontal line
is ending.

D.3.4 The Example for Designing Basic Program

Start, Stop and Latching
In the same occasions, it needs transient close button and transient open button to be start
and stop switch. Therefore, if you want to keep the action, you should design latching circuit.
There are several latching circuits in the following:

Example 1: the latching circuit for priority of stop

When start normally open contact X1=On, stop
normally contact X2＝Off, and Y1=On are set at
the same time, if X2=On, the coil Y1 will stop

X2
Y1

acting. Therefore, it calls priority of stop.

Example 2: the latching circuit for priority of start
When start normally open contact X1=On, stop

normally contact X2＝Off and Y1=On (coil Y1 will
be active and latching) are valid at the same time, if

X2=On, coil Y1 will be active due to latched
contact. Therefore, it calls priority of start.

Revision Oct. 2009, 07EE, SW--PW V1.14/CTL V2.14

D-13

Appendix D How to Use PLC Function|

Example 3: the latching circuit of SET and RST commands
The figure at the right side is latching circuit that made

Top priority of stop

up of RST and SET command.

SET

RST

It is top priority of stop when RST command is set
behind SET command. When executing PLC from up
to down, The coil Y1 is ON and coil Y1 will be OFF

when X1 and X2 act at the same time, therefore it calls Top priority of start
X2

priority of stop.
It is top priority of start when SET command is set after

RST

SET

RST command. When X1 and X2 act at the same
time, Y1 is ON so it calls top priority of start.

X1 and X3 can start/stop Y1 separately, X2 and X4 can start/stop Y2 separately and they are all
self latched circuit. Y1 is an element for Y2 to do AND function due to the normally open contact
connects to Y2 in series. Therefore, Y1 is the input of Y2 and Y2 is also the input of Y1.

The figure above is the circuit of interlock control. Y1 and Y2 will act according to the start
contact X1 and X2. Y1 and Y2 will act not at the same time, once one of them acts and the
other won’t act. (This is called interlock.) Even if X1 and X2 are valid at the same time, Y1 and
Y2 won’t act at the same time due to up-to-down scan of ladder diagram. For this ladder
diagram, Y1 has higher priority than Y2.

The figure above is a very simple ladder step diagram. When starting to scan Y1 normally
close contact, Y1 normally close contact is close due to the coil Y1 is OFF. Then it will scan
Y1 and the coil Y1 will be ON and output 1. In the next scan period to scan normally close
contact Y1, Y1 normally close contact will be open due to Y1 is ON. Finally, coil Y1 will be
OFF. The result of repeated scan, coil Y will output the vibrating pulse with cycle timeΔ
T(On)+ΔT(Off).

will be OFF, normally close M0 and normally close Y1 are all closed. However, coil Y1 will keep
on being ON and it will make coil Y1 to be OFF once a rising-edge comes after input X0 and coil
M0 is ON for a scan time. The timing chart is as shown above. This circuit usually executes
alternate two actions with an input. From above timing: when input X0 is a square wave of a

The Function of Input/output Contacts
The function of input contact X: input contact X reads input signal and enter PLC by
connecting with input equipment. It is unlimited usage times for A contact or B contact of
each input contact X in program. The On/Off of input contact X can be changed with the
On/Off of input equipment but can’t be changed by using peripheral equipment (WPLSoft).

The Function of Output Contact Y
The mission of output contact Y is to drive the load that connects to output contact Y by
sending On/Off signal. There are two kinds of output contact: one is relay and the other is
transistor. It is unlimited usage times for A or B contact of each output contact Y in program.
But there is number for output coil Y and it is recommended to use one time in program.
Otherwise, the output result will be decided by the circuit of last output Y with PLC program
scan method.

Decimal Number (DEC)
The suitable time for decimal number to use in DVP-PLC system.

To be the setting value of timer T or counter C, such as TMR C0 K50. (K constant)

To be the device number of M, T, C and D. For example: M10, T30. (device number)

To be operand in application command, such as MOV K123 D0. (K constant)

BCD (Binary Code Decimal, BCD)
It shows a decimal number by a unit number or four bits so continuous 16 bits can use to
represent the four numbers of decimal number. BCD code is usually used to read the input
value of DIP switch or output value to 7-segment display to be display.

Hexadecimal Number (HEX)
The suitable time for hexadecimal number to use in DVP-PLC system.

To be operand in application command. For example: MOV H1A2B D0. (constant H)

In PLC, it is usually have K before constant to mean decimal number. For example, K100
means 100 in decimal number.
Exception:
The value that is made up of K and bit equipment X, Y, M, S will be bit, byte, word or
double word. For example, K2Y10, K4M100. K1 means a 4-bit data and K2~K4 can
be 8, 12 and 16-bit data separately.
Constant H:
In PLC, it is usually have H before constant to mean hexadecimal number. For example,
H100 means 100 in hexadecimal number.

D.4.4 The Function of Auxiliary Relay
There are output coil and A, B contacts in auxiliary relay M and output relay Y. It is unlimited
usage times in program. User can control loop by using auxiliary relay, but can’t drive
external load directly. There are two types divided by its characteristics.
1. Auxiliary relay for general : It will reset to Off when power loss during running. Its state will
be Off when power on after power loss.
2. Auxiliary relay for special : Each special auxiliary relay has its special function. Please
don’t use undefined auxiliary relay.

D.4.5 The Function of Timer
The unit of timer is 1ms, 10ms and 100ms. The count method is count up. The output coil
will be On when the present value of timer equals to the settings. The setting is K in decimal
number. Data register D can be also used as settings.
The real setting time of timer = unit of timer * settings

Setting range of 16-bit counter is K0~K32,767. (K0 is the same as K1. output contact will
be On immediately at the first count.

General counter will be clear when PLC is power loss. If counter is latched, it will
remember the value before power loss and keep on counting when power on after power
loss.

If using MOV command, WPLSoft to send a value, which is large than setting to C0,
register, at the next time that X1 is from Off to On, C0 counter contact will be On and
present value will be set to the same as settings.

The setting of counter can use constant K or register D (not includes special data register
D1000~D1044) to be indirect setting.

If using constant K to be setting, it can only be positive number but if setting is data
register D, it can be positive/negative number. The next number that counter counts up
from 32,767 is -32,768.

Appendix D How to Use PLC Function|

Explanations:
1.

Operand D occupies 3 consecutive devices.

See the specifications of each model for their range of use.

The contents in S1 and S2 are compared and the result will be stored in D.

The two comparison values are compared algebraically and the two values are signed
binary values. When b15 = 1 in 16-bit instruction, the comparison will regard the value as
negative binary values.

Program Example:
1.

Designate device Y0, and operand D automatically occupies Y0, Y1, and Y2.

When X10 = On, CMP instruction will be executed and one of Y0, Y1, and Y2 will be On.
When X10 = Off, CMP instruction will not be executed and Y0, Y1, and Y2 remain their
status before X10 = Off.

If the user need to obtain a comparison result with ≥ ≤, and ≠, make a series parallel
connection between Y0 ~ Y2.

D-46

If K10 S2, the instruction performs comparison by using S1 as the lower/upper
bound.

The two comparison values are compared algebraically and the two values are signed
binary values. When b15 = 1 in 16-bit instruction or b31 = 1 in 32-bit instruction, the
comparison will regard the value as negative binary values.

Program Example:
1.

Designate device M0, and operand D automatically occupies M0, M1 and M2.

When X0 = On, ZCP instruction will be executed and one of M0, M1, and M2 will be On.
When X10 = Off, ZCP instruction will not be executed and M0, M1, and M2 remain their
status before X0 = Off.

Please use rising-edge/falling-edge command, such as LDP/LDF, for the contact
condition. Please notice that error may occur when using contact A/B for the contact
condition.

There are three input modes for high-speed counter in the following can be set by D1044.
A-B phase mode(4 times frequency )(D1044=0): user can input the A and B pulse for
counting. Make sure that

A, B

and GND are grounding.

Pulse + signal mode(D1044=1): user can count by pulse input or signal. A is for pulse and

Pulse + flag mode(D1044=2): user can count by M1030. Only A is needed for this mode

B is for signal. Make sure that
and make sure that

A, B

and GND are grounding.

A , and GND are grounding.

Program Example:
1.

Assume that when M100=ON, it is set to A-B phase mode. When M101=ON, it is set to
pulse+signal mode. When M102=ON, it is set to pulse+flag mode.

M1030 is used to set to count up (OFF) and count down (ON).

If M0 goes from OFF to ON, DHSCS command starts to execute the comparison of highspeed counter. When C235 goes from H’2 to H’3 or from H’4 to H’3, M3 will be always be
ON.

If M1 goes from OFF to ON, DHSCS command starts to execute the comparison of highspeed counter. When C235 goes from H’1004F to H’10050 or from H’10051 to H’10050,
M2 will be always be ON.

M1028: it is used to enable(ON)/disable(OFF) the high-speed counter function. M1029: it
is used to clear the high-speed counter. M1018: it is used to start high-speed counter
function. (when M1028 is ON).

SDO is used to access the Object Dictionary in every CANopen node by Client/Server model.
One SDO has two COB-ID (request SDO and response SDO) to upload or download data
between two nodes. No data limit for SDOs to transfer data. But it needs to transfer by
segment when data exceeds 4 bytes with an end signal in the last segment.
The Object Dictionary (OD) is a group of objects in CANopen node. Every node has an OD
in the system, and OD contains all parameters describing the device and its network
behavior. The access path of OD is the index and sub-index, each object has a unique index
in OD, and has sub-index if necessary.
The request and response frame structure of SDO communication is shown as follows:

E.1.4.3 PDO (Process Data Object)
PDO communication can be described by the producer/consumer model. Each node of the
network will listen to the messages of the transmission node and distinguish if the message
has to be processed or not after receiving the message. PDO can be transmitted from one
device to one another device or to many other devices.
Every PDO has two PDO services: a TxPDO and a RxPDO. PDOs are transmitted in a nonconfirmed mode.
PDO Transmission type is defined in the PDO communication parameter index (1400h for
the 1st RxPDO or 1800h for the 1st TxPDO), and all transmission types are listed in the
following table:

Type Number

241-251
252

RTR only

Type number 1-240 indicates the number of SYNC message between two PDO
transmissions.
Type number 252 indicates the data is updated (but not sent) immediately after receiving
SYNC.
Type number 253 indicates the data is updated immediately after receiving RTR.
Type number 254: Delta CANopen doesn’t support this transmission format.
