1.4 Disposing Unwanted Driver

U
V

When disposing the VFD, pay attention to the following

issues:
The electrolytic capacitors in the driver may explode
when they are burnt.
Poisonous gas may be generated when the plastic parts
like front covers are burnt.

Fig. 1-2 Capacitors are prohibited to be used.

Please dispose the drive as industrial waste.

Circuit breakers connected to the output of VFD
If circuit breaker or contactor needs to be connected
between the drive and the motor, be sure to operate these
circuit breakers or contactor when the drive has no
output, to avoid damaging of the drive.
Using VFD beyond the range of rated voltage
The drive is not suitable to be used out of the
specified range of operation voltage. If needed, please
use suitable voltage regulation device.
Protection from lightning
There is lighting-strike over-current device inside
the Drive which protects it against lighting.
Derating due to altitude
Derating must be considered when the drive is
installed at high altitude, greater than 1000m. This is
because the cooling effect of drive is deteriorated due to
the thin air, as shown in Fig.1-3 that indicates the
relationship between the altitude and rated current of the
driver.

Chapter 4 Wiring Guide of VFD
In this chapter we introduce the wiring of VFD

Danger
·Wiring can only be done after the drive’s AC power is disconnected, all the LEDs on the operation panel are off
and waiting for at least 10 minutes. Then, you can remove the panel.
·Wiring job can only be done after confirming the charge indicator on the right bottom is off and the voltage
between main circuit power terminals + and - is below DC36V.
·Wire connections can only be done by trained and authorized person
·Check the wiring carefully before connecting emergency stop or safety circuits.
·Check the drive’s voltage level before supplying power to it, otherwise human injuries or equipment damage
may happen.

! Attention
·Check whether the Variable Speed Drive’s rated input voltage is in compliant with the AC supply voltage
before using.
·Dielectric strength test of the drive has been done in factory, so you need not do it again.
·Refer to chapter 2 on connected braking resistor or braking kit.
·It is prohibited to connect the AC supply cables to the drive’s terminals U, V and W.
·Grounding cables should be copper cables with section area bigger than 3.5mm², and the grounding resistance
should be less than 10Ω.
·There is leakage current inside the drive. The total leakage current is greater than 3.5mA, depending on the
usage conditions. To ensure safety, both the drive and the motor should be grounded, and a leakage current
protector (RCD) should be installed. It is recommended to choose B type RCD and set the leakage current at
300mA.
·The drive should be connected to the AC supply via a circuit breaker or fuse to provide convenience to input
over-current protection and maintainance.

5.2 Operation mode of VFD
In the follow-up sections, you may encounter the terms describing the control, running and status of drive many times.
Please read this section carefully. It will help you to understand and use the functions discussed in the follow chapters
correctly.
5.2.1 Control mode of VFD
It defines the physical channels by which drive receives operating commands like START, STOP, JOG and others,
there are two channels:
1 Operation panel control: The drive is controlled by RUN, STOP and M keys on the operation panel;
2 Terminal control: The drive is controlled by terminals Xi、Xj and COM (2-wire mode), or by terminal Xki (3-wire
mode);
The control modes can be selected by function code A0.04, multi-function input terminal (Function No. 15~17 are
selected by A6.00~A6.06 ).
3 Modbus communication: by using host computer to control the VFD to start or stop.
Note:
Before you change the control mode, make sure that the mode suitable for the application. Wrong selection of control
mode may cause damage to equipment or human injury!
5.2.2 Operating Status
There are 3 operating status: stop, motor parameters auto-tuning, and operating.
1. Stop status: After the drive is switched on and initialized, if no operating command is accepted or the stop command
is executed, then the drive in stop status.
2. Operating status: The drive enters operating status after it receives the operating command.
3. Motor parameters auto-tuning status: If there is an operating command after b0.11 is set to 1 or 2, the drive then
enters motor parameters auto-tuning status, and then enters stopping status after auto-tuning process finishes.
5.2.3 Control mode and operation mode of Kinco VFD
Control mode
FV100 VFD has three control methods, it is set by A0.01:
1. Vector control without PG: it is vector control without speed sensor, need not to install the PG, at the same time it
has very high control performance, it can control the speed and torque of motor accurately. It has the characteristics
like low frequency with high torque and steady speed with high accuracy. It is often used in the applications that the
V/F control mode can not satisfy, but require high robustness.
2. Vector control with PG: The PG is needed, the PG is installed on the shaft of controlled motor to ensure the control
performance. It is used in the applications that require high torque response, and much higher accuracy of torque and
speed control.

3. V/F control: It is used in the applications that do not require very high performance, such as one VFD controls
multiple motors.
Operation mode
Speed control: Control the speed of motor accurately, related function codes in A5 group should be set.
Torque control: Control the torque of motor accurately, related function codes in A5 group should be set.
5.2.4 The channels to set the VFD frequency
FV100 supports 5 kinds of operating modes in speed control mode which can be sequenced according to the priority:
Jog>Close loop process operation>PLC operation>Multiple speed operation>simple operation. It is shown as follows:

Fig 5-4 Operating mode in speed control mode
The three operating modes provide three basic frequency source.Two of them can use the auxiliary frequency to
stacking and adjusting (except Jog mode), the descriptions of each mode are as follows:
1) JOG operation:
When the drive is in STOP state, and receives the JOG command (for example the M key on the panel is pressed), then
the drive jogs at the JOG frequency (refer to function code A2.04 and A2.05)
2) Close-loop process operation:
If the close-loop operating function is enabled (C1.00=1), the drive will select the close-loop operation mode, that is, it
will perform closed-loop regulation according to the given and feedback value (refer to function code C1 group). This
mode can be deactivated by the multi-function terminals, and switch to the lower priority mode.
27

3) PLC operation
This function is customized, description is omitted.
4) Multi-step (MS) speed operation:
Select Multiple frequency 1～15（C0.00～C0.14）to start Multiple speed operation by the ON/OFF combinations of the
multi-function terminals (No.27, 28, 29 and 30 function). If all the terminals are “OFF”,it is in simple operation.
Note:
About the frequency setting channel under speed mode, please refer to the chapter 6 for detail information

Chapter 8 Maintenance
Many factors such as ambient temperature, humidity, dust, vibration, internal component aging, wear and tear will give
rise to the occurrence of potential faults. Therefore, it is necessary to conduct routine maintenance to the drives.
Notes:
As safety precautions, before carrying out check and maintenance of the drive, please ensure that :
The drive has been switched off;
The charging LED lamp inside the drive is off.
Use a volt-meter to test the voltage between terminals (+) and (-) and the voltage should be below 36V.

8.1 Daily Maintenance
The drive must be operated in the environment specified in the Section 2.1. Besides, some unexpected accidents may
occur during operation. You should maintain the drive conditions according to the table below, record the operation
data, and find out problems in the early stage.

8.2 Periodical Maintenance
Customer should check the drive every 3 months or 6 months according to the actual environment.
Notes:
1. Only trained personnel can dismantle the drive to replace or repair components;
2. Don't leave metal parts like screws or pads inside the drive; otherwise the equipment may be damaged.
77

General Inspection:
1. Check whether the screws of control terminals are loose. If so, tighten them with a screwdriver;
2. Check whether the main circuit terminals are properly connected; whether the mains cables are over heated;
3. Check whether the power cables and control cables are damaged, check especially for any wear on the cable tube;
4. Check whether the insulating tapes around the cable lugs are stripped;
5. Clean the dust on PCBs and air ducts with a vacuum cleaner;
6. For drives that have been stored for a long time, it must be powered on every 2 years. When supplying AC
power to the drive, use a voltage regulator to raise the input voltage to rated input voltage gradually. The drive
should be powered for 5 hours without load.
7. Before performing insulation tests, all main circuit input/output terminals should be short-circuited with conductors.
Then proceed insulation test to the ground. Insulation test of single main circuit terminal to ground is forbidden;
otherwise the drive might be damaged.
Please use a 500V Mega-Ohm-Meter.
8. Before the insulation test of the motor, disconnect the motor from the drive to avoid damaging it.
Note:
Dielectric Strength test of the drive has already been conducted in the factory. Do not do the test again, otherwise, the
internal components might be damaged.
Using different component to substitute the original component may damage the driver.

8.3 Replacing Wearing Parts
The components that are easily damaged are: cooling fan and electrolytic capacitors of filters. Their lifetime depends
largely on their application environment and preservation. Normally, lifetime is shown in following table.
Table 8-2 Lifetime of components
Components

Lifetime

Fan

3~40,000 hours

electrolytic capacitor

4~50,000 hours

Relay

About 100,000 times

You can decide the time when the components should be replaced according to their service time.
1.Cooling fan
Possible cause of damages: wear of the bearing, aging of the fan vanes.
Criteria:After the drive is switched off, check whether abnormal conditions such as crack exists on fan vanes and other
parts. When the drive is switched on, check whether drive running is normal, and check whether there is any abnormal
vibration.
2. Electrolytic capacitors
Possible cause of damages: high ambient temperature, aging of electrolyte and large pulse current caused by rapid
changing loads.
Criteria: Check if there is any leakage of liquids. Check if the safety valve protrudes. Measure static capacitance and
insulation resistance.
3.Relay
Possible cause of damages: corrosion, frequent-switching.
Criteria: Check whether the relay has open and shut failure.
78

8.4 Storage
The following points must be followed for the temporary and long-term storage of drive:
1. Store in locations free of high temperature, humidity, dust, metal powder, and with good ventilation.
2. Long-term storage will cause the deterioration of electrolytic capacitors. Therefore, the drive must be switched on
for a test within 2 years at least for 5 hours. The input voltage must be boosted gradually by the voltage regulator to the
rated value.

Chapter 9 List of Parameters
FV100 series VFD’s parameters are organized in groups. Each group has several parameters that are identified by

Communication Protocol
1. Networking Mode
According to the following pic 10-1, there are two networking modes: Single master and multi-slave, Single master
and single slave.

Pic 10-1

2. Interfaces
RS485 or RS232: asynchronous, semi-duplex
Default: 8-N-1, 9600bps, RTU. See Group b3 for parameter settings.

3. Communication Modes
1. The communication protocol for the drive is Modbus. It support normal reading and writing of the registers, also
supports managing the function code.
2. The drive is a slave in the network. It communicates in “point to point” mode.
3. When there is multi-station communication or the communication distance is long, please connect a 100~200 ohm
resistance to the positive and minus terminal of the master’s signal wire in parallel.
4.FV 100 normally provides RS485 interface, if you need RS232, please choose to add a RS232/RS485 conversion
equipment.

118

119

4. Protocol Format
FV100 support Modbus RTU and ASCII, its frame format is shown in Fig.10-2.

Modbus use “Big Endian” of encoder mode,which means sending data with high byte in front and low byte behind.
1. RTU mode
In RTU mode,there must be a idle of at least 3.5 characters between two frames.It use CRC-16 for data check.

2．ASCII mode
In ASCII mode, characters are used to start and end a frame. The colon “0x3A” is used to flag the start of a message
and each message is ended with a “0x0D,0x0D” combination. Except frame header and end of frame,all other
messages are coded in hexadecimal values, represented with readable ASCII characters. Only the characters 0...9 and
A...F are used for coding. Herein the data use LRC as error checksum.
Following is an example for writing value 4000(0x0FA0) into the parameter of internal register 0201(A2.01) from
No.5 slave.

VFD can set different delay time for response according to different application.For RTU mode,the actual delay time
for response is 3.5 characters interval at least.For ASCII mode,the actual delay time for response is 1 ms at least.

5. Protocol Function
The main functions of Modbus are read and write parameters.Different function codes need different operation
request.The modbus protocol of VFD support the operations in the following table.
Function code

Meaning

0x03

Read parameters of VFD,including function code parameters,control parameters and status
parameters.

0x06

Rewrite single function code or control parameter with 16bit length,the value of the
parameter can’t be saved after VFD power off.

0x08

Diagnosis.

0x10

Rewrite multiple function code or control parameters,the value of the parameters can’t be
saved after VFD power off.

0x41

Rewrite single function code or control parameter with 16bit length,the value
can be saved after VFD power off.

0x42

Manage function code of VFD.

0x43

Rewrite multiple function code or control parameters,the value of the parameters can be
saved after VFD power off.

All the function code, control parameters and status parameters of VFD are mapping to the read/write register of
Modbus.The group number of function code is mapping to the high byte of register address and the index address in
the group is mapping to the low byte of register address.The corresponding relationship between group number and
register address is shown in following table.

Note

Some instructions
1．For function code 0x10 and 0x43,when rewrite multiple continous function codes,if any one of the function

codes is invalid for write operation,then it will return error information and all of the parameters can’t be
rewritten.When rewrite multiple continuous control parameters,if any one of the parameters is invalid for write
operation, then it will return error information and this parameter and others behind can’t be rewritten,but other
parameters before this parameter can be rewritten normally.
2．For some special function code,Using 0x06 and 0x41 or 0x10 and 0x43 are the same function,in write
operation,the parameters can be saved after power failure.

3．Some control parameters can’t save in EEPROM,so for these parameters,using function code 0x41 and 0x06 or
0x43and 0x10 are the same,mean parameters can be saved after power failure.
4．Some internal parameters of VFD are reserved and can’t be changed via communication,refer to following
table:

5．The operation of user password and factory password in host computer
（1）User password
1）Protection of user password:read/write function code,function code management(except “read address of
displaydata” and”switch display data”)
2）If you set user password（A0.00!=0）,then you must enter the right password to A0.00 when you want to visit
function code,but control parameters and status parameters are not protected by user password.
3）User password can’t be set,change or cancel by host computer,it can only operated by keypad. To A0.00 of
write operation, only effective in two situations: one is in the password decryption; Second,write 0 is in the situation of
no password.It will return invalid operation information in other situations.
4）The operation of host computer and keypad to user password is independent. Even if the keyboard complete
decryption, but host computer still need to decrypt when it want to access function codes, and vice versa.
5）After host computer acquire the access right of parameters,when reading user password,it will return “0000”
instead of actual user password.
6）The host computer will acquire the access right of function code after decryption,if there is no communication
for 5minutes,then the access right will disable.And if it want to access function code,it need to enter user password
again.
7）When host computer has acquired access right(no user password or has decryption),if the user password is
rewritten by keypad at this moment,the host computer has still the current access right and no need to decryption
again.
（2）Factory password
1）Protection range of factory password:read/write parameters of Group U0,function code management of Group
U0.

126

127

2）Host computer can only access function code of Group U0 after decryption(write correct factory password into
U0.00).If there is no communication for 5 minutes after acquiring access right,the right will disable automatically,and
it need to enter password again to access Group U0.
3）After acquiring the access right of Group U0,if host computer read U0.00,it will return 0000 instead of actual
factory password.
4）The operation of host computer and keypad to user password is independent. They need to enter the correct
password separately to acquire the access right.
5）Host computer has no right to modify factory password.When host computer write data into U0.00, it will
return invalid operation unless the data is correct password.

Scaling relationship of VFD:
A）Scaling of frequency C is 1：100.
If you want to make the VFD run at 50Hz,then the main reference should be set as 0x1388(5000).
B）Scaling of time is 1：10
If you want to set the acceleration time of the VFD as 30s,then the function code should be set as 0x012C(300).
C）Scaling of current is 1：10
If the response current of VFD is 0x012C (300), then current of the VFD is 30A.
D）Output power is the absolute value.
E）Other (such as the input and output terminals, etc.) please reference inverter user manual
