from AC Tech's factory. If, under normal use, an SCL/SCM motor control becomes defective

within the stated warranty time period, contact AC Technology's Service Department for

instructions on obtaining a warranty replacement unit. AC Technology Corporation reserves

the right to make the ﬁnal determination as to the validity of a warranty claim, and sole

obligation is to repair or replace only components which have been rendered defective

due to faulty material or workmanship. No warranty claim will be accepted for components

which have been damaged due to mishandling, improper installation, unauthorized repair

and/or alteration of the product, operation in excess of design speciﬁcations or other

misuse, or improper maintenance. AC Technology Corporation makes no warranty that its

products are compatible with any other equipment, or to any speciﬁc application, to which

they may be applied and shall not be held liable for any other consequential damage or

injury arising from the use of its products.

This warranty is in lieu of all other warranties, expressed or implied. No other person,

ﬁrm or corporation is authorized to assume, for AC Technology Corporation, any

other liability in connection with the demonstration or sale of its products.

1.4 Receiving

Inspect all cartons for damage which may have occurred during shipping. Carefully

unpack equipment and inspect thoroughly for damage or shortage. Report any damage

to carrier and/or shortages to supplier. All major components and connections should be

examined for damage and tightness, with special attention given to PC boards, plugs,

knobs and switches.

1.5 Safety Information

Some parts of AC Tech controllers can be electrically live and some surfaces can be hot.

Non-authorized removal of the required cover, inappropriate use, and incorrect installation

or operation creates the risk of severe injury to personnel or damage to equipment. All

operations concerning transport, installation, and commissioning as well as maintenance

must be carried out by qualiﬁed, skilled personnel familiar with the installation, assembly,

commissioning, and operation of variable frequency drives and the application in which

the drive is used.

3 SM01N

INSTALLATION

Ensure proper handling and avoid excessive mechanical stress. Do not bend any

components and do not change any insulation distances during transport, handling,

installation or maintenance.

Do not touch any electronic components or contacts. This drive contains electrostatically

sensitive components, which can easily be damaged by inappropriate handling. Static

control precautions must be adhered to during installation, testing, servicing and repairing

of this drive and associated options. Component damage may result if proper procedures

are not followed.

This drive has been tested by Underwriters Laboratory (UL) and is an approved component

in compliance with UL508C Safety Standard.

Warnings!

• Suitable for use on a circuit as described in Section 7.0 of this manual.

• Use minimum 75°C copper wire only.

• Shall be installed in a Pollution Degree 2 macro-environment.

This drive must be installed and conﬁgured in accordance with both national and international

standards. Local codes and regulations take precedence over recommendations provided

in this and other AC Tech documentation.

The drive is considered a component for integration into a machine or process. It is neither

a machine nor a device ready for use in accordance with European directives (reference

machinery directive and electromagnetic compatibility directive). It is the responsibility of

the end user to ensure that the machine meets the applicable standards.

ELECTRICAL CONNECTION

When working on live drive controllers, applicable national safety regulations must be

observed. The electrical installation must be carried out according to the appropriate

regulations (e.g. cable cross-sections, fuses, protective earth [PE] connection). While

this document does make recommendations in regards to these items, national and local

codes must be adhered to.

The documentation contains information about installation in compliance with EMC

(shielding, grounding, ﬁlters and cables). These notes must also be observed for CE-

marked controllers. The manufacturer of the system or machine is responsible for

compliance with the required limit values demanded by EMC legislation.

APPLICATION

The drive must not be used as a safety device for machines where there is a risk of

personal injury or material damage. Emergency Stops, over-speed protection, acceleration

and deceleration limits, etc must be made by other devices to ensure operation under

all conditions.

SM01N 4

The drive does feature many protection devices which are aimed at protecting the drive

and the driven equipment by generating a fault and shutting the drive and motor down by

removing power. Mains power variances can also result in shutdown of the drive. When

the fault condition disappears or is cleared, the drive can be conﬁgured to automatically

restart, it is the responsibility of the user, OEM and/or integrator to ensure that the drive

is conﬁgured for safe operation.

1.6 Customer Modiﬁcation

AC Technology Corporation, its sales representatives and distributors, welcome the

opportunity to assist our customers in applying our products. Many custom options are

available to aid in this function. AC Technology Corporation cannot assume responsibility

for any modiﬁcations not authorized by its engineering department.

6 INSTALLATION

NOTE

SCL/SCM Series drives are intended for inclusion within other equipment, by

professional electrical installers according to EN 61000-3-2. They are not intended

for stand-alone operation.

WARNING!

Drives must not be installed where subjected to adverse environmental conditions

such as: combustible, oily, or hazardous vapors or dust; excessive moisture or

dirt; vibration; excessive ambient temperatures. Consult AC Technology for more

information on the suitability of a drive to a particular environment.

SCL/SCM models are suitable for UL Pollution Degree 2 environment only, and MUST be

installed in an electrical enclosure that will provide complete mechanical protection and will

maintain the internal temperature within the drive’s ambient operating temperature rating.

All drive models MUST be mounted in a vertical position for proper heatsink cooling.

Maintain a minimum spacing around the drive of at least 1 inch (25 mm) on each side and

2 inches (50 mm) on the top and bottom for units up to 5 Hp (4 kW), and 2 inches (50 mm)

on each side and 4 inches (100 mm) on the top and bottom for larger units. Allow more

spacing if the drive is mounted next to other heat-producing equipment. Do not mount

drives above other drives or heat producing equipment. Fans or blowers should be used

to insure proper cooling in tight quarters.

In order to properly size an enclosure, the heat generated by the drive(s) must be known.

Refer to the HEAT LOSS column in Section 5.0, SCL/SCM RATINGS. An enclosure

manufacturer can then determine the required enclosure size based on the total heat

generated inside the enclosure (from the drive(s) and other heat sources), the maximum

allowable temperature inside the enclosure, the maximum ambient temperature outside

the enclosure, and the enclosure properties.

The SCL/SCM Series is UL approved for solid state motor overload protection. Therefore,

a separate thermal overload relay is not required for single motor applications.

6.1 Installation After a Long Period of Storage

STOP!

Severe damage to the drive can result if it is operated after a long period of storage

or inactivity without reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding three years

(due to storage, etc), the electrolytic DC bus capacitors within the drive can change

internally, resulting in excessive leakage current. This can result in premature failure of

the capacitors if the drive is operated after such a long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of

inactivity, apply input power to the drive for 8 hours prior to actually operating the motor.

SM01N 10

7 INPUT AC POWER REQUIREMENTS

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Before

servicing the drive, disconnect incoming power and wait until the voltage between

terminals B+ and B- is 0 VDC.

The input voltage must match the nameplate voltage rating of the drive. Voltage ﬂuctuation

must not vary by greater than 10% overvoltage or 15% undervoltage.

NOTE

Drives with dual input voltage ratings must be programmed for the proper supply

voltage (refer to Parameter 01 - LINE VOLTAGE SELECTION in Section 15,

DESCRIPTION OF PARAMETERS).

The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS

symmetrical amperes at the drive’s rated voltage.

If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating

of the drive(s), an isolation transformer or 2-3% input line reactor must be added to the

line side of the drive(s).

Three phase voltage imbalance must be less than 2.0% phase to phase. Excessive phase

to phase imbalance can cause severe damage to the drive.

Motor voltage should match line voltage in normal applications. The drive’s maximum

output voltage will equal the input voltage. Use extreme caution when using a motor with

a voltage rating which is different from the input line voltage.

7.1 Input Voltage Ratings

SM000S Series drives are rated for 120 Vac single phase, 50-60 Hz input. The drive will

function with input voltage of 120 Vac (+10%, -15%) at 48 to 62 Hz.

SM200S & SL200S Series drives are rated for 208/240 Vac, single phase, 50-60 Hz

input. The drive will function with input voltage of 208 to 240 Vac (+10%, -15%), at 48

to 62 Hz.

SM200 Series drives are rated for 208/240 Vac, three phase, 50-60 Hz input. The drive

will function with input voltage of 208 to 240 Vac (+10%, -15%) at 48 to 62 Hz.

SM400 Series drives are rated for 400/480 Vac, three phase, 50-60 Hz input. The drive

will function with input voltage of 400 to 480 Vac (+10%, -15%) at 48 to 62 Hz.

NOTE

Parameter 01 - LINE VOLTAGE SELECTION must be programmed according to the

applied input voltage. Refer to Section 15, DESCRIPTION OF PARAMETERS.

11 SM01N

7.2 Input Fusing Requirements

A circuit breaker or a disconnect switch with fuses must be provided in accordance with

the National Electric Code (NEC) and all local codes. Refer to the following tables for

proper ratings:

NOTE

• Applicable national and local electrical codes take precedence over

recommendations in these tables.

• Use UL Class CC fast-acting, current limiting type fuses. Select fuses with low

I 2 T values, rated at 200,000 AIC. Recommended fuses are Bussman KTK-R,

JJN, and JJS. Similar fuses with equivalent ratings by other manufacturers may

also be acceptable.

WARNING!

This product can cause a DC current in the protective conductor. Where a residual

current device (RCD) is used for protection in case of direct or indirect contact, only

an RCD of Type B is allowed on the supply side of this product. Otherwise, another

protective measure shall be applied, such as separation from the environment

by double or reinforced insulation, or isolation from the supply system by a

transformer.

Observe the following when using RCDs:

1. Only install the RCD between the supply mains and drive controller.

2. The RCD can be activated by:

- capacitive leakage currents between the cable screens during operation

(especially with long, screened motor cables)

- connecting several drives to the mains at the same time

- additional RFI ﬁlters

7.4 Installation According to EMC Requirements

The SCM and SCL Series can be installed to meet the European standards for

Electromagnetic Compatibility (EMC) requirements. These requirements govern the

permissible electromagnetic emissions and immunity, both radiated and conducted, of

a drive system.

The EMC requirements apply to the ﬁnal installation in its entirety, not to the individual

components used. Because every installation is different, the recommended installation

should follow these guidelines as a minimum. Additional equipment (such as ferrite core

absorbers on power conductors) or alternative wiring practices may be required to meet

conformance in some installations.

Filter: The input to the drive (or group of drives) must include a ﬁlter to reduce the electrical

noise reﬂected back to the AC Line. The SCL Series includes a ﬁlter that has been tested

to meet the industrial standards set by the EU, EN 61800-3 for conducted emissions and

EN 55011 for radiated emissions to class A compliance when installed in a control cabinet

with a motor cable < 10m. The SCM can be installed to meet these same standards when

used with an appropriately installed external line ﬁlter.

EMC

Compliance with EN 61800-3/A11

Installation: Shielded cable must be used for all control and power cables

and exposed wiring must be kept as short as possible.

8 POWER WIRING

DANGER!

Hazard of electrical shock! Capacitors retain charge after power is removed. Before

servicing the drive, disconnect the incoming power and wait until the voltage between

terminals B+ and B- is 0 VDC.

Note the drive input and output current ratings and the check applicable electrical codes for

required wire type and size, grounding requirements, over-current protection, and incoming

power disconnect, before wiring the drive. Size conservatively to minimize voltage drop.

Input fusing and a power disconnect switch or contactor MUST be wired in series with

terminals L1 and L2/N (on single-phase input models), or terminals L1, L2, and L3 (on

three-phase input models). This disconnect must be used to power down the drive when

servicing, or when the drive is not to be operated for a long period of time, but should not

be used to start and stop the motor.

Repetitive cycling of a disconnect or input contactor (more than once every two

minutes) may cause damage to the drive.

8.1 Input and Output Wiring

On single phase input models, wire the input power to terminals L1 and L2/N. On three

phase input models, wire the input power to terminals L1, L2, and L3. Refer to Section 9,

SCL/SCM POWER WIRING DIAGRAM.

Keep all three power output wires, from terminals U, V, and W to the motor, tightly bundled

and run them in a separate conduit away from all other power and control wiring.

It is not recommended to install contactors or disconnect switches between the drive and

motor. Operating such devices while the drive is running can potentially cause damage

to the drive's power components. If such a device is required, it should only be operated

when the drive is in a STOP state. If there is potential for the device to be opened while

the drive is running, the drive must be programmed for COAST to stop (refer to Parameter

4 - STOP METHOD), and an auxiliary contact on the device must be interlocked with the

drive's run circuit. This will give the drive a stop command at the same time the device

opens, and will not allow the drive to start again until the device is closed.

WARNING!

• DO NOT connect incoming AC power to output terminals U, V, W, or terminals

B+, B-! Severe damage to the drive will result.

• Leakage current may exceed 3.5 mA AC. Minimum size of the protective earth

(PE) conductor shall comply with local safety regulations for high leakage current

equipment.

NOTE

• WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL

APPLICABLE LOCAL CODES.

• Motor wires MUST be run in a separate steel conduit away from control wiring

and incoming AC power wiring.

• Do not install contactors between the drive and the motor without consulting AC

Technology for more information. Failure to do so may result in drive damage.

• Use only UL and CSA listed and approved wire.

• Minimum wire voltage rating is 300 V for 120, 208, and 240 Vac systems, and

600 V for 400 and 480 Vac systems.

• Wire gauge must be based on a minimum of 125% of the rated input/output current

of the drive, and a minimum 75°C insulation rating. Use copper wire only.

15 SM01N

10 CONTROL WIRING

10.1 Control Wiring vs. Power Wiring

External control wiring MUST be run in a separate conduit away from all other input and

output power wiring. If control wiring is not kept separate from power wiring, electrical noise

may be generated on the control wiring that will cause erratic drive behavior. Use twisted

wires or shielded cable grounded at the drive chassis ONLY. Recommended control wire

is Belden 8760 (2-wire), 8770 (3-wire), or equivalent.

NOTE

Control terminals provide basic isolation (insulation per EN 61800-5-1). Protection

against contact can only be assured by additional measures e.g. supplemental

insulation.

Strip off 0.20 to 0.25 inches (5 to 6 mm) of insulation for control wiring, and torque the

control terminals to 2 lb-in (0.2 Nm). Be careful not to overtorque the control terminals, as

this will cause damage to the terminal strip. This is not covered under warranty and can

only be repaired by replacing the control board.

10.2 TB-2: Circuit Common

The TB-2 terminal is used as circuit common for the analog speed reference inputs. If

necessary TB-2 may be connected to chassis ground.

10.3 Surge Suppression on Relays

Current and voltage surges and spikes in the coils of contactors, relays, solenoids, etc,

near or connected to the drive, can cause erratic drive operation. Therefore, a snubber

circuit should be used on coils associated with the drive. For AC coils, snubbers should

consist of a resistor and a capacitor in series across the coil. For DC coils, a free-wheeling

or ﬂyback diode should be placed across the coil. Snubbers are typically available from

the manufacturer of the device.

10.4 Start/Stop Control

There are various control schemes that allow for 2-wire and 3-wire Start/Stop circuits. Refer

to the wiring diagrams in Section 11, SCL/SCM CONTROL WIRING DIAGRAMS.

10.5 Speed Reference Signals

The drive allows for three analog speed reference inputs:

SPEED POT Connect the wiper of a speed pot to terminal TB-5, and connect the high

and low end leads to terminals TB-6 and TB-2, respectively. The speed

pot can be 2.5kΩ up to 10kΩ.

0-10 VDC Wire the positive to terminal TB-5 and the negative to terminal TB-2. TB-5

input impedance is 120kΩ.

4-20 mA Wire the positive to terminal TB-25 and the negative to terminal TB-2.

TB-25 input impedance is 250Ω.

SM01N 16

10.6 Speed Reference Selection

If an analog speed reference input is used to control the drive speed, terminal TB-13A,

13B, or 13E (Parameter 10, 11, or 12) may be programmed as the input select for the

desired analog input signal. When that TB-13 terminal is then closed to TB-11, the drive

will follow the selected analog speed reference input.

If an analog speed reference input is not selected on the terminal strip using TB-13A, 13B,

or 13E, speed control will default to STANDARD mode, which is governed by the setting

of STANDARD SPEED SOURCE (Parameter 05). The STANDARD SPEED SOURCE

can be the  and  buttons on the front of the drive, PRESET SPEED #1 (Parameter

31), a 0-10 VDC signal, or a 4-20 mA signal.

0 - 10 VDC and 4 - 20 mA INPUT SIGNALS

TB-13A, TB-13B, and TB-13E can all be programmed to select a 0-10 VDC or 4-20 mA

analog speed reference input.

PRESET SPEEDS

TB-13A can be programmed to select PRESET SPEED #1 (04), TB-13B to select

PRESET SPEED #2 (04), and TB-13E to select PRESET SPEED #3 (04). There are a

total of seven preset speeds, which are activated by different combinations of contact

closures between TB-13A, 13B, 13E and TB-11. Refer to Parameters 31-37 in Section

15, DESCRIPTION OF PARAMETERS.

JOG

TB-13B can be programmed to select either JOG FORWARD (07) or JOG REVERSE

(08). The Jog speed is set by PRESET SPEED #2 (Parameter 32). Close TB-13B to

TB-11 to JOG, and open the contact to STOP.

WARNING!

When operating in JOG mode, the STOP signal and the AUXILIARY STOP function

(see Parameters 10-12) WILL NOT stop the drive. To stop the drive, remove the

JOG command.

JOG REVERSE will operate the drive in reverse rotation even if ROTATION

DIRECTION (Parameter 17) is set to FORWARD ONLY.

NOTE

If the drive is commanded to JOG while running, the drive will enter JOG mode

and run at PRESET SPEED #2. When the JOG command is removed, the drive

will STOP.

MOTOR OPERATED POT (MOP) / FLOATING POINT CONTROL

TB-13B and TB-13E are used for this function, which controls the drive speed using

contacts wired to the terminal strip. Program TB-13B for DECREASE FREQ (05), and

program TB-13E for INCREASE FREQ (05). Closing TB-13B to TB-11 will cause the

speed setpoint to decrease until the contact is opened. Closing TB-13E to TB-11 will

cause the speed setpoint to increase until the contact is opened. The INCREASE FREQ

function will only operate while the drive is running.

17 SM01N

NOTE

If TB-13A, TB-13B, and TB-13E are all programmed to select speed references, and

two or three of the terminals are closed to TB-11, the higher terminal has priority and

will override the others. For example, if TB-13A is programmed to select 0-10VDC,

and TB-13E is programmed to select PRESET SPEED #3, closing both terminals

to TB-11 will cause the drive to respond to PRESET SPEED #3, because TB-13E

overrides TB-13A.

The exception to this is the MOP function, which requires the use of TB-13B and TB-

13E. This leaves TB-13A to be used for some other function. If TB-13A is programmed

for a speed reference, and TB-13A is closed to TB-11, TB-13A will override the MOP

function.

10.7 Drive Status Digital Outputs

There is one Form A relay at terminals TB-16 and TB-17. The relay contacts are rated 3

amps at 250 Vac.

Terminal TB-13E can also be conﬁgured as a digital output. This output circuit is a current-

sourcing type rated at 12 VDC and 50 mA maximum.

The Form A relay and digital output can be programmed to indicate any of the following:

RUN, FAULT, INVERSE FAULT, FAULT LOCKOUT, AT SPEED, ABOVE PRESET SPEED

#3, CURRENT LIMIT, AUTO SPEED MODE, and REVERSE. Refer to Parameters 06

and 12 in Section 15, DESCRIPTION OF PARAMETERS.

The diagram below illustrates how TB-13E, when conﬁgured as a digital output, can be

used to drive an external relay:

12 INITIAL POWER UP AND MOTOR ROTATION

DANGER!

Hazard of electrical shock! Wait three minutes after disconnecting incoming power

before servicing drive. Capacitors retain charge after power is removed.

STOP!

• DO NOT connect incoming AC power to output terminals U, V, and W or

terminals B+, B-! Severe damage to the drive will result. Do not continuously

cycle input power to the drive more than once every two minutes. Damage to

the drive will result.

• Severe damage to the drive can result if it is operated after a long

period of storage or inactivity without reforming the DC bus capacitors!

Refer to Section 6.1, Installation After a Long Period of Storage

Before attempting to operate the drive, motor, and driven equipment, be sure all procedures

pertaining to installation and wiring have been properly followed.

Disconnect the driven load from the motor. Verify that the drive input terminals (L1 and

L2/N, or L1, L2, and L3) are wired to the proper input voltage per the nameplate rating

of the drive.

Energize the incoming power line. The LED display will ﬂash a three digit number (320

in the example below) that identiﬁes the parameter version contained in the drive. The

display should then read “- - -”, which indicates that the drive is in a STOP condition. This

is shown below:

Apply input power

Display then reads "- - -"

Display ﬂashes parameter

version (300-399)

Follow this 4-step procedure to check the motor rotation. This procedure assumes that

the drive has been powered up for the ﬁrst time, and that none of the parameters have

been changed.

1. Use the  button to decrease the speed setpoint to 00.0 Hz. The left decimal point

will illuminate as the speed setpoint is decreased. If the  button is held down, the

speed setpoint will decrease by tenths of Hz until the next whole Hz is reached, and

then it will decrease by one Hz increments. Otherwise, each push of the  button will

decrease the speed setpoint by a tenth of a Hz.

Once 00.0 Hz is reached, the display will toggle between “00.0” and “- - -”, which

indicates that the drive is in a STOP condition with a speed setpoint of 00.0 Hz.

2. Give the drive a START command. This can be done using one of several wiring

methods described in Section 11, SCL/SCM CONTROL WIRING DIAGRAMS. Once

the START command is issued, the display will read “00.0”, indicating that the drive

is in a RUN condition with a speed setpoint of 00.0 Hz.

23 SM01N

3. Use the  button to increase the speed setpoint until the motor starts to rotate. The left

decimal point will light as the speed setpoint is increased. If the  button is held down,

the speed setpoint will increase by tenths of Hz until the next whole Hz is reached,

and then it will increase by one Hz increments. Otherwise, each push of the button

will increase the speed setpoint by a tenth of a Hz.

4. If the motor is rotating in the wrong direction, give the drive a STOP command and

remove power from the drive. Wait three minutes for the bus capacitors to discharge,

and swap any two of the motor wires connected to U, V, W.

NOTE

The drive is phase insensitive with respect to incoming line voltage. This means

that the drive will operate with any phase sequence of the incoming three phase

voltage. Therefore, to change the motor rotation, the phases must be swapped at

the drive output terminals or at the motor.

SM01N 24

13 PROGRAMMING THE SCL/SCM DRIVE

The drive may be programmed by one of two methods: using the three buttons and 3-digit

LED display on the front of the drive, or by programming the Electronic Programming

Module (EPM) using the optional EPM Programmer. This section describes programming

the drive using the buttons and display, which are shown below:

BUTTONS DISPLAY

Mode

To enter the PROGRAM mode to access the parameters, press the Mode button. This will

activate the PASSWORD prompt (if the password has not been disabled). The display will

read “00” and the upper right-hand decimal point will be blinking, as shown below:

Press Mode

Upper right decimal point blinks

Display reads "00"

Use the  and  buttons to scroll to the password value (the factory default password

is “225”) and press the Mode button. Once the correct password value is entered, the

display will read "P01", which indicates that the PROGRAM mode has been accessed at

the beginning of the parameter menu (P01 is the ﬁrst parameter). This is shown below:

Press Mode to enter password

TIME)

Once the desired parameter number is found, press the Mode button to display the present

parameter setting. The upper right-hand decimal point will begin blinking, indicating that

the present parameter setting is being displayed, and that it can be changed by using

the  and  buttons.

Press Mode to display present

parameter setting (example set-

ting is 20.0)

Upper right decimal point blinks

Use  and  to change setting

(example setting changed to

Press Mode to store new setting

Pressing Mode will store the new setting and also exit the PROGRAM mode. To change

another parameter, press the Mode key again to re-enter the PROGRAM mode (the

parameter menu will be accessed at the parameter that was last viewed or changed before

exiting). If the Mode key is pressed within two minutes of exiting the PROGRAM mode,

the password is not required access the parameters. After two minutes, the password

must be entered in order to access the parameters again.

13.1 Setting Values in Tenths of Units Above 100

Parameter settings and the keypad speed command can always be adjusted in tenths of

unit increments from 0.0 to 99.9. Above 100 however, values can be set in whole units or

tenths of units, depending on the setting of Parameter 16 - UNITS EDITING.

If Parameter 16 - UNITS EDITING is set to WHOLE UNITS (02), parameter values and

the keypad speed command can only be adjusted by whole unit increments above 100.

For example, Parameter 19 - ACCELERATION TIME could not be set to 243.7 seconds.

It could only be set to 243 or 244 seconds. Likewise, the keypad speed command (set

using the  and  buttons) could not be set to 113.4 Hz. It could only be set to 113 or

114 Hz.

SM01N 26

If, however, Parameter 16 - UNITS EDITING is set to TENTHS OF UNITS (01), parameter

values and the keypad speed command can be adjusted in tenths of unit increments up

to a value of 1000 (above 1000, whole unit increments only). Each push of the  or 

button will adjust the value by one tenth of a unit. If the  or  button is pressed and

held, the value will increment by tenths of units until the next whole unit is reached, and

then the value will increment by whole units.

When a value above 100 is being adjusted by tenths of units, the value is shifted to the

left by one digit so that the tenths portion of the value can be displayed. This results in

the ﬁrst digit (reading from left to right) of the value disappearing from the display. Also,

the lower decimal point will blink to indicate that the actual value is above 100. Once

the value is no longer being adjusted, the value will shift back to the right and the tenths

portion of the value will disappear.

In the example below, Parameter 19 - ACCELERATION TIME is presently set to 243.0

seconds, and is being increased to 243.7 seconds.

Go to Parameter 19 and press

Mode to see present setting ("243"

13.2 Electronic Programming Module (EPM)

Every SCL/SCM Series drive has an Electronic Programming Module (EPM) installed on

the main control board. The EPM stores the user’s parameter settings and special OEM

default settings (if programmed). The EPM is removable, allowing it to be installed in

another drive for quick set-up. For example, if a drive is being replaced with a new one,

the EPM can be taken out of the ﬁrst drive and installed in the new drive. Downtime is

minimized because the new drive does not require programming - it is ready to run when

the EPM is installed.

27 SM01N

The SCL/SCM Series drive contains two or three sets of parameter values, depending on

whether the drive has been programmed with optional OEM default settings. The ﬁrst set

of values is the factory default settings, which are permanently stored on the main control

board and cannot be changed. The second set of values is the user settings, which are

stored in the EPM. When the drive leaves the factory, the user settings are the same as

the factory default settings, but the user settings can be changed to conﬁgure the drive

for a particular application. The optional third set of values is the OEM default settings,

which are also stored in the EPM. OEM default settings are typically used in cases where

many drives are used for the same application, which requires that all of the drives have

the same parameter settings. The OEM default settings cannot be changed without the

optional EPM Programmer. The drive can be programmed to operate according to the user

settings or the OEM default settings (Refer to Parameter 48 in Section 15).

NOTE

The drive will not operate without the EPM installed. The drive will display “F1” if

the EPM is missing or damaged.

STOP!

Do not remove the EPM while power is applied to the drive. Damage to the EPM

and/or drive may result.

The optional EPM Programmer has the ability to quickly and easily program many SC

Series drives for the same conﬁguration. Once a “master” EPM is programmed with the

desired parameter settings, the EPM Programmer can then copy those settings to other

EPMs, allowing many drives to be conﬁgured very quickly. Consult the EPM Programmer

Instruction Manual or contact the factory for more information.

If the OEM settings in the EPM become corrupted, the drive will operate normally, until an

attempt is made to perform a RESET OEM using Parameter 48, PROGRAM SELECTION.

The drive will then ﬂash “GF” to indicate that the OEM settings are no longer valid. The

EPM must then be re-programmed using the optional EPM Programmer.

If the OEM settings and the user settings are both corrupted, the drive will display “GF”

immediately and the drive will require a RESET 60 or RESET 50 using Parameter 48,

PROGRAM SELECTION. Once the RESET is performed, the parameters can then be

programmed individually to match the OEM default settings. This will allow the drive to

operate as if it were in OEM mode, even though it is actually operating in USER mode.

Refer to Parameter 48 in Section 15, DESCRIPTION OF PARAMETERS.

NOTE

The drive will also display “GF” if a RESET OEM or OPERATE WITH OEM SETTINGS

is attempted when the EPM does not contain OEM defaults.

15 DESCRIPTION OF PARAMETERS

P01 LINE VOLTAGE SELECTION

Parameter P01 calibrates the drive for the actual applied input voltage. Set this parameter

to HIGH (01) for 120, 220-240, and 460-480 Vac input, or LOW (02) for 200-208 and

380-415 Vac input.

NOTE

If this parameter is changed while the drive is running, the new value will not take

effect until the drive is stopped.

P02 CARRIER FREQUENCY

Parameter P02 sets the switching rate of the output IGBT’s. Increasing the carrier

frequency will result in less audible motor noise. Available settings are: 4 kHz, 6 kHz, 8

kHz, and 10 kHz.

04 10 kHz 35°C or 92%

NOTE

• The SCL/SCM drive is fully rated up to 8 kHz carrier frequency. If the 10 kHz

carrier frequency is selected, the drive’s ambient temperature rating OR output

current rating must be de-rated to the value shown in the table above.

• If this parameter is changed while the drive is running, the change will not take

effect until the drive is stopped.

P03 START METHOD

WARNING!

Automatic starting of equipment may cause damage to equipment and/or injury to

personnel! Automatic start should only be used on equipment that is inaccessible

to personnel.

01 NORMAL: The drive will start when the appropriate contact is closed on the terminal

strip. See Section 11 for possible control conﬁgurations.

02 START ON POWER UP: The drive will automatically start upon application of input

power.

SM01N 32

03 START WITH DC BRAKE: When a START command is given, the drive will apply DC

BRAKE VOLTAGE (Parameter 22) for the duration of DC BRAKE TIME (Parameter

21) prior to starting the motor to ensure that the motor is not turning.

04 AUTO RESTART WITH DC BRAKING: Upon a START command, after a fault, or

upon application of power, the drive will apply DC BRAKE VOLTAGE (Parameter 22)

for the duration of DC BRAKE TIME (Parameter 21) prior to starting (or restarting)

the motor.

05 FLYING RESTART 1: LOW performance. Slowest synchronization and lowest current

level. This setting results in the smoothest synchronization.

06 FLYING RESTART 2: MEDIUM performance. Faster synchronization and

higher current level. This setting allows faster synchronization while retaining

smoothness.

07 FLYING RESTART 3: HIGH performance. Fastest synchronization and highest current

level. This setting allows the fastest synchronization, but sacriﬁces smoothness.

When programmed for auto-restart (settings 04 - 07), the drive will attempt three restarts

after a fault. The interval between restart attempts is 15 seconds for setting 04, and 2

seconds for settings 05, 06 and 07. During the interval between restart attempts, the display

will read “SP” to indicate Start Pending. If all three restart attempts fail, the drive will trip

into FAULT LOCKOUT (displayed “LC”) and require a manual reset. Refer to Section 16,

TROUBLESHOOTING.

The FLYING RESTART 1 - 3 settings allow the drive to start into a spinning load after a fault

or upon application of input power. They differ in the time required to ﬁnd the motor speed

and the amount of current required to synchronize with it. The faster the drive attempts

to ﬁnd the motor speed, the more current is required. The ﬁrst two restart attempts will try

to start into the spinning load, but the third restart attempt will act like AUTO RESTART

WITH DC BRAKING.

NOTE

Settings 02 and 04 - 07 require a two-wire start/stop circuit to operate. The RUN

contact must remain closed for the power-up start and auto-restart functions to

operate.

P04 STOP METHOD

01 COAST TO STOP: When a STOP command is given, the drive shuts off the output

to the motor, allowing it to coast freely to a stop.

02 COAST WITH DC BRAKE: When a stop command is given, the drive will activate

DC braking (after a delay of up to 2 seconds, depending on frequency) to help

decelerate the load. Refer to Parameters: 21 - DC BRAKE TIME, and 22 - DC BRAKE

VOLTAGE.

03 RAMP TO STOP: When a stop command is given, the drive will decelerate the motor

to a stop at the rate determined by Parameter 20 - DECELERATION TIME.

33 SM01N

04 RAMP WITH DC BRAKE: When a stop command is given, the drive will decelerate

the motor down to 0.2 Hz (at the rate set by Parameter 20 - DECELERATION TIME)

and then activate DC braking according to the settings of Parameters 21 - DC BRAKE

TIME and 22 - DC BRAKE VOLTAGE. This is used to bring the load to a ﬁnal stop,

as the motor may still be turning slightly after the drive stops.

P05 STANDARD SPEED SOURCE

P05 selects the speed reference source when the drive is in STANDARD speed mode.

The following speed references can be selected:

01 KEYPAD: Use the  and  buttons to scroll to the desired speed.

02 PRESET SPEED #1: Drive will operate at the frequency set in Parameter 31.

03 0-10 VDC: Drive will respond to a 0-10 VDC signal wired to TB-5 (+) and TB-2 (-).

04 4-20 mA: Drive will respond to a 4-20 mA signal wired to TB-25 (+) and TB-2 (-).

P06 RELAY OUTPUT

P06 selects the status indication for the normally open relay output at TB-16 and TB-17:

01 NONE: Disables the relay output.

02 RUN: Closes upon a START command. Opens if the drive is in a STOP state, the

drive faults, or input power is removed. DC braking is considered a STOP state.

03 FAULT: Closes if there is no fault condition. Opens if the drive faults, or input power

is removed.

04 INVERSE FAULT: Closes if the drive faults. Opens if there is no fault condition.

05 FAULT LOCKOUT: Closes when input power is applied. Opens if three restart attempts

are unsuccessful, or if input power is removed.

06 AT SET SPEED: Closes if the drive is within + 0.5 Hz of the speed setpoint.

07 ABOVE PRESET SPEED #3: Closes if the output frequency exceeds PRESET

SPEED #3 (Parameter 33). Opens if the output frequency is equal to or less than

PRESET SPEED #3.

08 CURRENT LIMIT: Closes if the output current exceeds the CURRENT LIMIT setting.

Opens if the output current is equal to or less than CURRENT LIMIT (see Parameter

25).

09 AUTOMATIC SPEED MODE: Closes if an AUTOMATIC (terminal strip) speed

reference is active. Opens if a STANDARD (Parameter 5) speed reference is

active.

10 REVERSE: Closes when reverse rotation is active. Opens when forward rotation is

active (see Parameter 17 - ROTATION DIRECTION).

ONLY (02).

NOTE

If the drive is commanded to JOG while running, the drive will enter JOG mode and

run at PRESET SPEED #2 (Parameter 32). When the JOG command is removed,

the drive will STOP.

P12 TB-13E FUNCTION SELECT

Parameter P12 selects the function of terminal TB-13E. This terminal can be conﬁgured

as a digital input (settings 01 to 10) or a digital status output (settings 11 to 20). When

used as an input, closing TB-13E to TB-11 (or opening in the case of settings 07 and 09)

commands from the optional remote keypad. Terminals 13B and 13E must also be

set for the REMOTE KEYPAD option (refer to Parameters 12 and 13).

P16 UNITS EDITING

P16 allows parameter and keypad speed editing in whole units or tenths of units above

100. Below 100, the value can always be changed by tenths of units.

01 TENTHS OF UNITS: The value can always be changed by tenths of units (up to a

value of 1000). If the  or  button is pressed and held, the value will change by

tenths of units until the next whole unit is reached, and then the value will change by

whole units. Refer to Section 13.1, Setting Values in Tenths of Units Above 100.

02 WHOLE UNITS: The value can be changed by tenths of units until 99.9 is reached.

Above 99.9, the value will change in whole unit increments only. Below a value of

100, if the  or  button is pressed and held, the value will change by tenths of units

until the next whole unit is reached, and then the value will change by whole units.

P17 ROTATION DIRECTION

01 FORWARD ONLY: The drive will only allow rotation in the forward direction. However,

JOG REVERSE (see Parameter 11) will still operate even if FORWARD ONLY is

selected.

02 FORWARD AND REVERSE: The drive will allow rotation in both directions.

P19 ACCELERATION TIME

P19 sets the acceleration rate for all of the speed reference sources (keypad, speed pot,

jog, MOP, and preset speeds). This setting is the time to accelerate from 0 Hz to the BASE

FREQUENCY (Parameter 27).

SM01N 38

P20 DECELERATION TIME

P20 sets the deceleration rate for all of the speed reference sources (keypad, speed pot, jog,

MOP, and preset speeds). This setting is the time to decelerate from BASE FREQUENCY

to 0 Hz. If the drive is set for COAST TO STOP (setting 01 or 02 in Parameter 04), this

parameter will have no effect when a STOP command is given.

P21 DC BRAKE TIME

P21 sets the length of time that the DC braking voltage is applied to the motor. The DC

BRAKE TIME should be set to the lowest value that provides satisfactory operation in

order to minimize motor heating.

P22 DC BRAKE VOLTAGE

P22 sets the magnitude of the DC braking voltage, in percentage of the line voltage. The

point at which the DC braking is activated depends on the selected STOP METHOD

(Parameter 04):

If COAST WITH DC BRAKE is selected, braking is activated after a time delay of up to 2

seconds, depending on the output frequency at the time of the STOP command. In this

case, the DC braking is the only force acting to decelerate the load.

If RAMP WITH DC BRAKE is selected, braking is activated when the output frequency

reaches 0.2 Hz. In this case, the drive decelerates the load to a near stop and then DC

braking is used to bring the load to a ﬁnal stop.

P23 MINIMUM FREQUENCY

P23 sets the minimum output frequency of the drive for all speed reference sources except

the PRESET SPEEDS (Parameters 31-37), and is used with MAXIMUM FREQUENCY

(Parameter 24) to deﬁne the operating range of the drive.

When using an analog input speed reference (0-10 VDC or 4-20 mA), Parameters 45

and 46 (SPEED AT MIN SIGNAL and SPEED AT MAX SIGNAL) also affect the drive's

speed range.

NOTE

If this parameter is changed while the drive is running, the new value will not take

effect until the drive is stopped.

P24 MAXIMUM FREQUENCY

P24 sets the maximum output frequency of the drive for all speed reference sources,

and is used with MINIMUM FREQUENCY (Parameter 23) to deﬁne the operating range

of the drive.

When using an analog input speed reference (0-10 VDC or 4-20 mA), Parameters 45 and

46 (SPEED AT MIN SIGNAL and SPEED AT MAX SIGNAL) also affect the drive's speed

range.

39 SM01N

NOTE

If this parameter is changed while the drive is running, the new value will not take

effect until the drive is stopped.

P25 CURRENT LIMIT

P25 sets the maximum allowable output current of the drive. The maximum setting is

either 180% or 150%, depending on whether LINE VOLTAGE SELECTION (Parameter

01) is set to HIGH or LOW.

If the load demands more current than the CURRENT LIMIT setting, the drive will reduce

the output frequency in an attempt to reduce the output current. When the overcurrent

condition passes, the drive will accelerate the motor back up to the speed setpoint.

P26 MOTOR OVERLOAD

The SCL/SCM Series is UL approved for solid state motor overload protection, and

therefore does not require a separate thermal overload relay for single motor applications.

This circuit allows the drive to deliver up to 150% current for one minute. If the overload

circuit “times out”, the drive will trip into an OVERLOAD fault (displayed as "PF"). MOTOR

OVERLOAD should be set to the ratio (in percent) of the motor current rating to the drive's

output current rating to properly protect the motor.

Example: A 3 HP, 480 Vac drive with a 4.8 Amp rating is operating a 2 HP motor with a

current rating of 3.4 Amps. Dividing the motor current rating by the drive's output current

rating yields 71% (3.4 / 4.8 = 0.71 = 71%), so this parameter should be set to 71%.

P27 BASE FREQUENCY

The BASE FREQUENCY determines the V/Hz ratio by setting the output frequency at

which the drive will output full voltage to the motor. In most cases, the BASE FREQUENCY

should be set to match the motor’s rated frequency.

Example: A 230 Vac, 60 Hz motor requires a V/Hz ratio of 3.83 (230 V / 60 Hz = 3.83

V/Hz) to produce full torque. Setting the BASE FREQUENCY to 60 Hz causes the drive

to output full voltage (230 Vac) at 60 Hz, which yields the required 3.83 V/Hz. Output

voltage is proportional to output frequency, so the 3.83 V/Hz ratio is maintained from 0

- 60 Hz, allowing the motor to produce full torque from about 2 Hz (below 2 Hz there is

less torque due to slip) up to 60 Hz.

NOTE

If this parameter is changed while the drive is running, the new value will not take

effect until the drive is stopped.

SM01N 40

P28 FIXED BOOST

FIXED BOOST increases starting torque by increasing the output voltage when operating below

half of the base frequency. For better out-of-the-box performance, SCL/SCM Series drives

are shipped with a setting that is different from the factory default of 1%. Units rated 0.33 to 1

HP (0.25 to 0.75 kW) = 5.3%, 1.5 to 2 HP (1.1 to 1.5 kW) = 4.4%, 3 HP (2.2 kW) = 3.6%, 5 HP

(4 kW) = 3.0%, 7.5 HP (5.5 kW) = 2.7%, 10 HP (7.5 kW) = 2.4%, and 15 HP (11 kW) =

2.2%.

P29 ACCELERATION BOOST

ACCELERATION BOOST helps accelerate high-inertia loads. During acceleration, the

output voltage is increased to increase motor torque. Once the motor reaches the new

speed setpoint, the boost is turned off and the output voltage returns to the normal

value.

P30 SLIP COMPENSATION

SLIP COMPENSATION is used to counteract changes in motor speed (slip) caused by

changes in load. In a standard AC induction motor, the shaft speed decreases as load

increases, and increases as load decreases. By increasing or decreasing the output

frequency in response to an increasing or decreasing load, the slip is counteracted and

speed is maintained. Most standard NEMA B motors have a 3% slip rating.

P31 - P37

PRESET SPEED #1 - #7

Preset speeds are activated by contact closures between TB-11 and TB-13A, 13B, and

13E. The TB-13 terminals must be programmed as preset speed selects using Parameters

10-12.

NOTE

Preset speeds can operate below the frequency deﬁned by the Minimum Frequency

parameter (Parameter 23).

Refer to the table below for activation of the preset speeds using the TB-13 terminals:

SPEED # TB - 13A TB - 13B TB - 13E

1 CLOSED OPEN OPEN

2 OPEN CLOSED OPEN

3 OPEN OPEN CLOSED

4 CLOSED CLOSED OPEN

5 CLOSED OPEN CLOSED

6 OPEN CLOSED CLOSED

7 CLOSED CLOSED CLOSED

NOTE

When a TB-13 terminal is programmed for a function other than a preset speed

select, it is considered OPEN for the table above.

41 SM01N

Preset Speed #6 and #7 can also be used as skip frequencies to restrict the drive from

operating at frequencies that cause vibration in the system. Refer to Parameter 38.

P38 SKIP BANDWIDTH

The SCL/SCM drive has two skip frequencies that can be used to lock out critical

frequencies that cause mechanical resonance in the system. Once SKIP BANDWIDTH is

set to a value other than 0 Hz, the skip frequencies are enabled. When the skip frequency

function is enabled, PRESET SPEED #6 and #7 are used as the skip frequencies. SKIP

BANDWIDTH sets the range above the skip frequencies that the drive will not operate

within.

Example: The critical frequency is 23 Hz, and it is desired to skip a frequency range of

3 Hz above and below the critical frequency (therefore the skip range is 20 to 26 Hz).

PRESET SPEED #6 or #7 would be set to 20 Hz, and the SKIP BANDWIDTH would be

set to 6 Hz.

If the drive is running at a speed below the skip range, and it is given a speed command

that is within the skip range, the drive will accelerate to the start of the skip range (20 Hz

in the example) and run at that speed until the speed command is greater than or equal to

the "top" of the skip range. The drive will then accelerate through the skip range to the new

speed. Likewise, if the drive is running at a speed above the skip range, and it is given a

speed command that is within the skip range, the drive will decelerate to the "top" of the

skip range (26 Hz in the example) and run at that speed until the speed command is less

than or equal to the "bottom" of the skip range. The drive will then decelerate through the

skip range to the new speed.

NOTE

PRESET SPEEDS #6 and #7 can still be used as preset speeds even if they are

also being used as skip frequencies.

P39 SPEED SCALING

Parameter P39 scales the display to indicate speed in units other than frequency. This

parameter should be set to the desired display value when the drive output is 60 Hz. The

highest setting is 6500, and the highest value that can be displayed is 6553.6. If SPEED

SCALING is set to 0.0, the speed scaling function is disabled and the display will indicate

frequency.

Example: A machine produces 175 parts per hour when the motor is running at 60 Hz.

Setting SPEED SCALING to 175 will calibrate the drive's display to read 175 when the

motor is running at 60 Hz. This is a linear function, so at 30 Hz the display would read

87.5 Hz, and at 120 Hz the display would read 350.

SM01N 42

NOTE

• If the displayed value will exceed 999, the value is shown in two parts. For

example, if the displayed value is 1800, the display will indicate this by toggling

between "1--" and "800".

• If SPEED SCALING is set such that the maximum displayable value (6553.6) is

exceeded, the display will ﬂash "9999" to indicate that the value is out of range.

For example, if SPEED SCALING is set to 6000, the drive will display 6000

when it is running at 60 Hz. If the speed is increased past 65.5 Hz (at 65.5 Hz,

the scaled value would be 6550), the display will ﬂash "9999" because a scaled

value above 6553.6 cannot be displayed.

P42 ACCEL / DECEL #2

Parameter P42 sets the second acceleration and deceleration rate of the drive, which can

be activated using terminals TB-13A, 13B, or 13E (Parameter 10, 11, or 12).

P44 PASSWORD

P44 allows the PASSWORD to be changed to any number between 000 and 999. Setting

PASSWORD to 000 disables the password function. The factory default password is

225.

P45 SPEED AT MIN SIGNAL

P45 sets the speed at which the drive will run when it receives the minimum speed

reference signal (0 VDC or 4 mA). This is used in conjunction with SPEED AT MAX

SIGNAL (Parameter 46) to deﬁne the speed range of the drive when following an analog

speed reference signal.

P46 SPEED AT MAX SIGNAL

P46 sets the speed at which the drive will run when it receives the maximum speed

reference signal (10 VDC or 20 mA). This is used in conjunction with SPEED AT MIN

SIGNAL (Parameter 45) to deﬁne the speed range of the drive when following an analog

speed reference signal.

NOTE

If SPEED AT MIN SIGNAL is set higher than SPEED AT MAX SIGNAL, the drive

will react inversely to the speed reference signal. Therefore, as the speed reference

signal increases, the drive speed will decrease, and vice-versa.

P47 CLEAR FAULT HISTORY

01 MAINTAIN: Maintains the FAULT HISTORY (Parameter 50) entries for

troubleshooting.

02 CLEAR: Erases the FAULT HISTORY (Parameter 50) entries.

43 SM01N

P48 PROGRAM SELECTION

P48 is used to select whether the drive will operate according to the user settings or the

optional OEM default settings, and to reset the parameters to default settings. Refer to

Section 13.2.

01 OPERATE WITH USER SETTINGS: The drive will operate according to the user

settings. Operation in USER mode allows the parameter values to be changed to

suit any application.

02 OPERATE WITH OEM DEFAULTS: The drive will operate according to the optional

OEM default settings, which conﬁgure the drive for a speciﬁc application. When

operating in OEM mode, the parameter values can be viewed, but not changed. If

an attempt is made to change a parameter setting, the display will ﬂash “GE”. If the

drive is not programmed with OEM default settings, the display will ﬂash “GF” if this

option is selected.

03 RESET OEM: Resets the user parameters to the OEM default settings. If the drive

is not programmed with OEM default settings, the display will ﬂash “GF” if this option

is selected.

04 RESET 60: Resets the user parameters to the factory defaults for a 60 Hz base

frequency. Parameters 24, 27, and 46 will reset to 60.0 Hz.

05 RESET 50: Resets the user parameters to the factory defaults for a 50 Hz base

frequency. Parameters 24, 27, and 46 will reset to 50.0 Hz.

06 TRANSLATE: If an EPM from a drive with a previous (but compatible) parameter

version is installed in a new drive, the new drive will function like the previous version

drive, but none of the parameter settings can be changed ("cE" will be displayed if this

is attempted). The TRANSLATE function converts the EPM to the new parameter

version so that the parameters can be changed, but it also retains the old parameter

settings so the new drive will operate like the old drive without having to re-program

all of the parameters. Once the EPM is "translated", it will no longer work in the old

drive.

NOTE

• If the user parameters are reset to the OEM defaults (using the RESET OEM

option), and then OPERATE WITH USER SETTINGS is selected, the USER

settings will be the same as the OEM default settings. This allows the drive to

operate as if it was in OEM mode, but the parameter values can be changed.

This is useful if some of the OEM default settings need to be ﬁne-tuned for proper

operation. The new parameter values are not actually stored as new OEM default

settings however; they are simply stored as new USER settings. Therefore, if

the parameters are reset to the OEM defaults again, the parameters that were

changed will be reset to their “old” value. The optional EPM Programmer is

required to change OEM default settings. Refer to Section 13.2.

• Only the TRANSLATE (06) function can be performed while the drive is running.

The display will ﬂash "Er" if an attempt is made to select any other function while

the drive is running.

SM01N 44

P50 FAULT HISTORY

The FAULT HISTORY stores the last eight faults that tripped the drive. Refer to Section

16, TROUBLESHOOTING for a list of the faults and possible causes.

Use the  and  buttons to scroll through the fault entries. The faults are stored from

newest to oldest, with the ﬁrst fault shown being the most recent.

The display will read “_ _” if the FAULT HISTORY does not contain any fault messages.

P51 SOFTWARE VERSION

Parameter P51 displays the software version number for the control board software. This

information is useful when contacting the factory for programming or troubleshooting

assistance.

The software version is displayed in two parts which alternate. The ﬁrst part is the software

version, and the second part is the revision number. For example, if the display ﬂashes

"94" and "02", this indicates that the drive contains the second revision of version 94

software.

P52 DC BUS VOLTAGE

P52 displays the DC bus voltage in percent of nominal. Nominal DC bus voltage is

determined by multiplying the drive’s nameplate input voltage rating by 1.4.

P53 MOTOR VOLTAGE

P53 displays the output voltage in percent of the drive’s nameplate output voltage

rating.

P54 MOTOR LOAD

P54 displays the motor load in percent of the drive’s output current rating.

P55 0-10 VDC INPUT

Parameter P55 displays the level of the 0-10 VDC input signal at TB-5. A reading of 100%

indicates a 10 VDC input at TB-5.

P56 4-20 mA INPUT

Parameter P56 displays the level of the 4-20 mA input signal at TB-25. A reading of

20% indicates a 4 mA input at TB-25, and a reading of 100% indicates a 20 mA input at

TB-25.

16 TROUBLESHOOTING

To aid in troubleshooting, Parameters 50 through 60 can be accessed without entering the

PASSWORD. Simply press the Mode button twice to “skip” over the PASSWORD prompt,

and “P50” will be displayed to indicate that the parameter menu has been entered and

Parameter 50 (FAULT HISTORY) can be viewed. The  and  buttons can then be used

to scroll from Parameter 50 to Parameter 60. Once the desired parameter is found, press

the Mode button to view its “contents”. When ﬁnished, press Mode to exit the parameter

menu. An example is shown herein:

Press Mode once

Upper right decimal point blinks

Display reads "00"

Press Mode again

Display reads "P50" (FAULT HISTORY)

Use  and  to scroll to the desired

parameter number

(In this example Parameter 54 has been

selected, which is MOTOR LOAD)

Press Mode to view parameter con-

tents (77 = 77% LOAD)

Press Mode again to exit

Upper right decimal point blinks

In the example above, Parameter 54 - MOTOR LOAD is being viewed. The “77” in the

example indicates that the load on the motor is 77% of the output current rating of the

drive.

The table herein lists the fault conditions that will cause the drive to shut down, as well

as some possible causes. Contact the factory for more information on troubleshooting

faults.

47 SM01N

FAULT MESSAGES

FAULT DESCRIPTION & POSSIBLE CAUSES

AF High Temp. Fault: Ambient temperature is too high; Cooling fan has failed (if

equipped).

CF Control Fault: A blank EPM, or an EPM with corrupted data has been installed. Per-

form a factory reset using Parameter 48 - PROGRAM SELECTION.

Incompatibility Fault: An EPM with an incompatible parameter version has been in-

stalled. Either remove the EPM or perform a factory reset (Parameter 48) to change

the parameter version of the EPM to match the parameter version of the drive.

dF Dynamic Braking Fault: The drive has sensed that the dynamic braking resistors are

overheating and shuts down to protect the resistors.

EF External Fault: One of the TB-13 terminals is set as an External Fault input and that

terminal is open with respect to TB-11. Refer to Parameters 10, 11 and 12.

GF Data Fault: User data and OEM defaults in the EPM are corrupted.

High DC Bus Voltage Fault: Line voltage is too high; Deceleration rate is too fast;

Over-hauling load. For fast deceleration or overhauling loads, dynamic braking may

be required

JF Remote Keypad Fault: The communication link between the drive and the optional

Remote Keypad has been lost. Check for proper wiring and/or noise.

LF Low DC Bus Voltage Fault: Line voltage is too low.

Output Transistor Fault: Phase to phase or phase to ground short circuit on the

output; Boost settings are too high; Acceleration rate is too fast; Failed output tran-

sistor.

PF Current Overload Fault: VFD is undersized for the application; Mechanical problem

with the driven equipment.

Start Fault: Start command was present when the drive was powered up. Must

wait 2 seconds after power-up to apply Start command if START METHOD is set to

NORMAL.

F1 EPM Fault: The EPM is missing or damaged.

FC,

F2 - F9,

Internal Faults: The control board has sensed a problem - consult factory.

To clear a fault, issue a STOP command on the terminal strip. The fault will only clear if

the condition that caused the fault has passed. For example, if the drive trips on a LOW

DC BUS VOLTAGE FAULT (LF) due to low input voltage, the fault cannot be cleared until

the input voltage returns to a normal level.

If the drive is programmed to automatically restart after a fault (see Parameter 03), the

drive will attempt to restart three times after a fault (the drive will not restart after CF, cF,

GF, FC, F1, F2-F9, or Fo faults). If all three restart attempts are unsuccessful, the drive will

trip into FAULT LOCKOUT (LC), which requires a manual reset as described above.

SM01N 48

17 SCL/SCM DISPLAY MESSAGES

The following paragraphs describe the various displays and messages that can appear

on the SCL/SCM drive.

17.1 Speed Display

If the drive is in a STOP state (indicated by "- - -" on the display), and the commanded

speed is changed, the display will show the commanded speed, and the upper left decimal

point will turn on solid. About ﬁve seconds after a change is made, the display will begin to

alternate between the commanded speed value and the "- - -" display. If the Mode button

is pressed, the display will stop alternating and show the "- - -" display only.

When the drive is given a START command, the displayed speed will start increasing as

the drive accelerates up to the commanded speed. If the commanded speed is changed

while the drive is running, the display will show the commanded speed rather than the

actual speed, until the actual speed reaches the commanded speed.

If the commanded speed is changed faster than the drive can accelerate or decelerate,

the upper left decimal point will blink to indicate that the the drive is accelerating or

decelerating to the new speed. Once the actual speed reaches the commanded speed,

the upper left decimal point will turn on solid for 5 seconds and then turn off to indicate

that the commanded speed has been reached, and that the display is now showing the

actual speed.

17.2 Changing the Speed Reference Source

When the speed source is changed while the drive is running, the display will ﬂash the

message for the new speed source to indicate that the new speed source is active. Also,

if the drive is being controlled from a speed source other than the  and  buttons (0-10

VDC, 4-20 mA, etc), and one of the  or  buttons is pressed, the display will ﬂash the

present speed source message to indicate that the  and  buttons are invalid.

Example 1: The drive is running and the present speed source is the keypad. TB-13A is

programmed to select a 4-20 mA signal as the speed source. When TB-13A is closed to

TB-11, the display will ﬂash “EI” to indicate that the speed source has changed to the 4-20

mA signal. If the contact between TB-13A and TB-11 is opened, the display will ﬂash “CP”

to indicate that the speed source has changed back to the  and  buttons.

Example 2: The speed source is a 0-10 VDC signal. If the  or  button is pushed, the

display will ﬂash “EU” to indicate that the present speed source is the 0-10 VDC signal

and that the  and  buttons are invalid.

49 SM01N

Refer to the following table for the possible speed reference source displays:

SPEED SOURCE DISPLAYS

DISPLAY DESCRIPTION

CP CONTROL PAD: Speed is set using the  and  buttons on the front of the drive.

EI EXTERNAL CURRENT: Speed is controlled by a 4-20 mA signal wired to TB-25 and TB-2

EU EXTERNAL VOLTAGE: Speed is controlled by a 0-10 VDC signal wired to TB-5 and TB-2.

JG JOG: The drive is in Jog mode, and the speed is set by Preset Speed #2 (Parameter 32).

OP MOP (Motor Operated Pot): Contacts wired to TB-13B and TB-13E are used to increase

and decrease the drive speed.

Pr1 - Pr7 PRESET SPEEDS #1-7: Speed is set by the indicated Preset Speed (Parameters 31-37).

NOTE

The speed source displays will ﬂash when the speed reference source is changed

while the drive is running to indicate that the new speed reference source is

active

17.3 Status and Warning Messages

STATUS AND WARNING MESSAGES

DISPLAY DESCRIPTION

br DC BRAKING: The DC braking circuit is activated.

“cE” will be displayed if an EPM with a different parameter version is installed and then

an attempt is made to change parameter settings without performing the TRANSLATE

function. Refer to PROGRAM SELECTION (Parameter 48).

CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting

(Parameter 25) and the drive is reducing the output frequency to reduce the output

current. If the drive remains in CURRENT LIMIT for too long, it can trip into a CURRENT

OVERLOAD fault (PF).

Er ERROR: Invalid data has been entered or an invalid command was attempted.

GE “GE” will be displayed if an attempt is made to change the OEM default settings when

the drive is operating in the OEM mode (refer to Parameter 48).

If “GF” is displayed when a RESET OEM is attempted, it indicates that the OEM defaults

in the EPM are corrupted. If “GF” is displayed upon power-up, it indicates that the OEM

defaults and the user settings in the EPM are corrupted. Refer to Section 13.2.

LC FAULT LOCKOUT: The drive has failed three restart attempts and now requires a manual

reset.

SE SERIAL: The optional remote keypad is active as the user interface instead of the

buttons on front of the drive. Refer to Parameter 14 (CONTROL).

SP START PENDING: “SP” blinks during the interval between restart attempts.

DECEL OVERRIDE (both upper decimal points blinking): The drive has stopped decelerating

to avoid tripping into an HF fault due to regenerative energy from the motor.
