4.5 Wiring Main Circuits
4.5.1 Wiring at input side of main circuit
4.5.1.1 Circuit breaker
It is necessary to connect a circuit breaker which is compatible with the capacity of inverter between 3ph AC power supply and power input terminals (R, S, T). The capacity of breaker is 1.5~2 times to the rated current of inverter. For details, see
<Specifications of Breaker, Cable, and Contactor>.
4.5.1.2 Contactor
In order to cut off the input power effectively when something is wrong in the system, contactor should be installed at the input side to control the on/off of the main circuit
23
Wiring power supply.
In order to prevent the rectifier damage resulted from the large current, AC reactor should be installed at the input side. It can also prevent rectifier from sudden variation of power voltage or harmonic generated by phase-control load.
4.5.1.4 Input EMC filter
The surrounding device may be disturbed by the cables when the inverter is working.
EMC filter can minimize the interference. Just like the following figure.
Figure 4.13 Wiring at input side of main circuit.
4.5.2 Wiring at inverter side of main circuit
4.5.2.1 DC reactor
Inverter from 18.5kW to 90kW have built-in DC reactor which can improve the power factor.
4.5.2.2 Braking unit and braking resistor
• Inverter of 15KW and below have built-in braking unit. In order to dissipate the regenerative energy generated by dynamic braking, the braking resistor should be installed at (+) and PB terminals. The wire length of the braking resistor should be less than 5m.
• Inverter of 18.5KW and above need connect external braking unit which should be installed at (+) and (-) terminals. The cable between inverter and braking unit should be less than 5m. The cable between braking unit and braking resistor should be less than 10m.
• The temperature of braking resistor will increase because the regenerative energy will be transformed to heat. Safety protection and good ventilation is recommended.
24
Wiring
Notice: Be sure that the electric polarity of (+) (-) terminals is right; it is not allowed to connect (+) with (-) terminals directly, otherwise damage or fire could occur.
4.5.3 Wiring at motor side of main circuit
4.5.3.1 Output Reactor
When the distance between inverter and motor is more than 50m, inverter may be tripped by over-current protection frequently because of the large leakage current resulted from the parasitic capacitance with ground. And the same time to avoid the damage of motor insulation, the output reactor should be installed.
4.5.3.2 Output EMC filter
EMC filter should be installed to minimize the leak current caused by the cable and minimize the radio noise caused by the cables between the inverter and cable.
Just see the following figure.
Figure 4.14 Wiring at motor side of main circuit.
4.5.4 Wiring of regenerative unit
Regenerative unit is used for putting the electricity generated by braking of motor to the grid. Compared with traditional 3 phase inverse parallel bridge type rectifier unit, regenerative unit uses IGBT so that the total harmonic distortion (THD) is less than 4%.
Regenerative unit is widely used for centrifugal and hoisting equipment.
Figure 4.15 Wiring of regenerative unit.

Wiring
4.5.5 Wiring of Common DC bus
Common DC bus method is widely used in the paper industry and chemical fiber industry which need multi-motor to coordinate. In these applications, some motors are in driving status while some others are in regenerative braking (generating electricity) status. The regenerated energy is automatically balanced through the common DC bus, which means it can supply to motors in driving status. Therefore the power consumption of whole system will be less compared with the traditional method (one inverter drives one motor).
When two motors are running at the same time (i.e. winding application), one is in driving status and the other is in regenerative status. In this case the DC buses of these two inverters can be connected in parallel so that the regenerated energy can be supplied to motors in driving status whenever it needs. Detailed wiring is shown in the following figure:
Figure 4.16 Wiring of common DC bus.
Notice: Two inverters must be the same model when connected with Common DC bus method. Be sure they are powered on at the same time.
4.5.6 Ground Wiring (PE)
In order to ensure safety and prevent electrical shock and fire, PE must be grounded with ground resistance. The ground wire should be big and short, and it is better to use copper wire (>3.5mm
2 ). When multiple inverters need to be grounded, do not loop the ground wire.
4.6 Wiring Control Circuits
4.6.1 Precautions z Use shielded or twisted-pair cables to connect control terminals. z Connect the ground terminal (PE) with shield wire.
26
Wiring z The cable connected to the control terminal should leave away from the main circuit and heavy current circuits (including power supply cable, motor cable, relay and contactor connecting cable) at least 20cm and parallel wiring should be avoided.
It is suggested to apply perpendicular wiring to prevent inverter malfunction caused by external interference.

4.7 Installation Guidline to EMC Compliance
4.7.1 General description of EMC
EMC is the abbreviation of electromagnetic compatibility, which means the device or system has the ability to work normally in the electromagnetic environment and will not generate any electromagnetic interference to other equipments.
EMC includes two subjects: electromagnetic interference and electromagnetic anti-jamming.
According to the transmission mode, Electromagnetic interference can be divided into two
28
Wiring categories: conducted interference and radiated interference.
Conducted interference is the interference transmitted by conductor. Therefore, any conductors (such as wire, transmission line, inductor, capacitor and so on) are the transmission channels of the interference.
Radiated interference is the interference transmitted in electromagnetic wave, and the energy is inverse proportional to the square of distance.
Three necessary conditions or essentials of electromagnetic interference are: interference source, transmission channel and sensitive receiver. For customers, the solution of EMC problem is mainly in transmission channel because of the device attribute of disturbance source and receiver can not be changed
4.7.2 EMC features of inverter
Like other electric or electronic devices, inverter is not only an electromagnetic interference source but also an electromagnetic receiver. The operating principle of inverter determines that it can produce certain electromagnetic interference noise. And the same time inverter should be designed with certain anti-jamming ability to ensure the smooth working in certain electromagnetic environment. The following is its EMC features:
4.7.2.1 Input current is non-sine wave. The input current includes large amount of high-harmonic waves that can cause electromagnetic interference, decrease the grid power factor and increase the line loss.
4.7.2.2 Output voltage is high frequency PMW wave, which can increase the temperature rise and shorten the life of motor. And the leakage current will also increase, which can lead to the leakage protection device malfunction and generate strong electromagnetic interference to influence the reliability of other electric devices.
4.7.2.3 As the electromagnetic receiver, too strong interference will damage the inverter and influence the normal using of customers.
4.7.2.4 In the system, EMS and EMI of inverter coexist. Decrease the EMI of inverter can increase its EMS ability.
4.7.3 EMC Installation Guideline
In order to ensure all electric devices in the same system to work smoothly, this section,
29
Wiring based on EMC features of inverter, introduces EMC installation process in several aspects of application (noise control, site wiring, grounding, leakage current and power supply filter). The good effective of EMC will depend on the good effective of all of these five aspects.
All the connections to the control terminals must use shielded wire. And the shield layer of the wire must ground near the wire entrance of inverter. The ground mode is 360 degree annular connection formed by cable clips. It is strictly prohibitive to connect the twisted shielding layer to the ground of inverter, which greatly decreases or loses the shielding effect.
Connect inverter and motor with the shielded wire or the separated cable tray. One side of shield layer of shielded wire or metal cover of separated cable tray should connect to ground, and the other side should connect to the motor cover. Installing an EMC filter can reduce the electromagnetic noise greatly.
Power supply wiring: the power should be separated supplied from electrical transformer.
Normally it is 5 core wires, three of which are fire wires, one of which is the neutral wire, and one of which is the ground wire. It is strictly prohibitive to use the same line to be both the neutral wire and the ground wire
Device categorization: there are different electric devices contained in one control cabinet, such as inverter, filter, PLC and instrument etc, which have different ability of emitting and withstanding electromagnetic noise. Therefore, it needs to categorize these devices into strong noise device and noise sensitive device. The same kinds of device should be placed in the same area, and the distance between devices of different category should be more than 20cm.
Wire Arrangement inside the control cabinet: there are signal wire (light current) and power cable (strong current) in one cabinet. For the inverter, the power cables are categorized into input cable and output cable. Signal wires can be easily disturbed by power cables to make the equipment malfunction. Therefore when wiring, signal cables and power cables should be arranged in different area. It is strictly prohibitive to arrange them in parallel or interlacement at a close distance (less than 20cm) or tie them together.
If the signal wires have to cross the power cables, they should be arranged in 90 angles.
Power input and output cables should not either be arranged in interlacement or tied
30
Wiring together, especially when installed the EMC filter. Otherwise the distributed capacitances of its input and output power cable can be coupling each other to make the EMC filter out of function.
4.7.3.3 Ground
Inverter must be ground safely when in operation. Grounding enjoys priority in all EMC methods because it does not only ensure the safety of equipment and persons, but also is the simplest, most effective and lowest cost solution for EMC problems.
Grounding has three categories: special pole grounding, common pole grounding and series-wound grounding. Different control system should use special pole grounding, and different devices in the same control system should use common pole grounding, and different devices connected by same power cable should use series-wound grounding.
Leakage current includes line-to-line leakage current and over-ground leakage current.
Its value depends on distributed capacitances and carrier frequency of inverter. The over-ground leakage current, which is the current passing through the common ground wire, can not only flow into inverter system but also other devices. It also can make leakage current circuit breaker, relay or other devices malfunction. The value of line-to-line leakage current, which means the leakage current passing through distributed capacitors of input output wire, depends on the carrier frequency of inverter, the length and section areas of motor cables. The higher carrier frequency of inverter, the longer of the motor cable and/or the bigger cable section area, the larger leakage current will occur.
Countermeasure:
Decreasing the carrier frequency can effectively decrease the leakage current. In the case of motor cable is relatively long (longer than 50m), it is necessary to install AC reactor or sinusoidal wave filter at the output side, and when it is even longer, it is necessary to install one reactor at every certain distance.
EMC filter has a great effect of electromagnetic decoupling, so it is preferred for customer to install it.
For inverter, noise filter has following categories: z Noise filter installed at the input side of inverter; z Install noise isolation for other equipment by means of isolation transformer or
31

Under the third-class menu, if the parameter has no flickering bit, it means the function code cannot be modified. The possible reasons could be: z This function code is not modifiable parameter, such as actual detected parameter, operation records and so on; z This function code is not modifiable in running status, but modifiable in stop status
5.2.2 Fault reset
If the inverter has fault, it will prompt the related fault information. User can use
STOP/RST or according terminals determined by P5 Group to reset the fault. After fault reset, the inverter is at stand-by state. If user does not reset the inverter when it is at fault state, the inverter will be at operation protection state, and can not run.
5.2.3 Motor parameter autotuning
If “Sensorless Vector Control” mode is chosen, motor nameplate parameters must be input correctly as the autotuning is based on it. The performance of vector control depends on the parameters of motor strongly, so to achieve excellent performance, firstly must obtain the parameter of motor exactly.
The procedure of motor parameter autotuning is as follows:
Firstly, choose the keypad command channel as the operation command channel
(P0.01).
And then input following parameters according to the actual motor parameters:
P2.00: motor rated power.
P2.01: motor rated frequency;
P2.02: motor rated speed;
P2.03: motor rated voltage;
P2.04: motor rated current
Notice: the motor should be uncoupled with its load; otherwise, the motor parameters obtained by autotuning may be not correct.
Set P0.12 to be 1, and for the detail process of motor parameter autotuning, please refer to the description of Function Code P0.12. And then press RUN on the keypad panel, the inverter will automatically calculate following parameter of the motor:
35
Operation
P2.05: motor stator resistance;
P2.06: motor rotor resistance;
P2.07: motor stator and rotor inductance;
P2.08: motor stator and rotor mutual inductance;
P2.09: motor current without load; then motor autotuning is finished.
5.2.4 Password setting
CHE series inverter offers user’s password protection function. When P7.00 is set to be nonzero, it will be the user’s password, and After exiting function code edit mode, it will become effective after 1 minute. If pressing the PRG/ESC again to try to access the function code edit mode, “0.0.0.0.0”will be displayed, and the operator must input correct user’s password, otherwise will be unable to access it.
If it is necessary to cancel the password protection function, just set P7.00 to be zero.
5.3 Running State
5.3.1 Power-on initialization
Firstly the system initializes during the inverter power-on, and LED displays “-CHE-”. After the initialization is completed, the inverter is on stand-by status.
5.3.2 Stand-by
At stop or running status, parameters of multi-status can be displayed. Whether or not to display this parameter can be chosen through Function Code P7.06(Running status display selection ) and P7.07 (Stop status display selection) according to binary bits, the detailed description of each bit please refer the function code description of P7.06 and
P7.07.

If the carrier frequency is increased, it will cause better current wave, less harmonic current and lower noise of motor.
Notice: z The factory setting is optimal in most cases. Modification of this parameter is not recommended. z If the carrier frequency exceeds the factory setting, the inverter must be derated because the higher carrier frequency will cause more switching loss, higher temperature rise of inverter and stronger electromagnetic interference.
If the carrier frequency is lower than the factory setting, it is possible to cause less output torque of motor and more harmonic current.

Optimize the responsiveness by adjusting these parameters while driving an actual load.
Use the following procedure to activate PID control and then adjust it while monitoring the response.
1. Enabled PID control (P0.03=5)
2. Increase the proportional gain (Kp) as far as possible without creating oscillation.
3. Reduce the integral time (Ti) as far as possible without creating oscillation.
4. Increase the differential time (Td) as far as possible without creating oscillation.
Making fine adjustments:
First set the individual PID control constants, and then make fine adjustments. z Reducing
If overshooting occurs, shorten the differential time and lengthen the integral time.

1: For normal motor, the lower the speed, the poorer the cooling effect. Based on this reason, if output frequency is lower than 30Hz, inverter will reduce the motor overload protection threshold to prevent normal motor from overheat.

If PB.03 is set to be 0, the trip-free function is invalid.
Trip-free function enables the inverter to perform low-voltage compensation when DC bus voltage drops below PB.02. The inverter can continue to run without tripping by reducing its output frequency and feedback energy via motor.
Notice: If PB.03 is too big, the feedback energy of motor will be too large and may cause over-voltage fault. If PB.03 is too small, the feedback energy of motor will be too small to achieve voltage compensation effect. So please set PB.03 according to load inertia and the actual load.

During deceleration, the motor’s decelerating rate may be lower than that of inverter’s output frequency due to the load inertia. At this time, the motor will feed the energy back to the inverter, resulting in DC bus voltage rise. If no measures taken, the inverter will trip due to over voltage.
During deceleration, the inverter detects DC bus voltage and compares it with over-voltage stall protection point. If DC bus voltage exceeds PB.05, the inverter will stop reducing its output frequency. When DC bus voltage become lower than PB.05, the deceleration continues, as shown in following figure.

Auto current limiting is used to limit the current of inverter smaller than the value determined by PB.06 in real time. Therefore the inverter will not trip due to surge over-current. This function is especially useful for the applications with big load inertia or step change of load.
PB.06 is a percentage of the inverter’s rated current.
PB.07 defines the decrease rate of output frequency when this function is active. If PB.06 is too small, overload fault may occur. If it is too big, the frequency will change too sharply and therefore, the feedback energy of motor will be too large and may cause over-voltage fault. This function is always enabled during acceleration or deceleration.
Notice:
During auto current limiting process, the inverter’s output frequency may change; therefore, it is recommended not to enable the function when requires the inverter’s output frequency stable.
During auto current limiting process, if PB.06 is too low, the overload capacity will be impacted.

Communication Protocol
10. COMMUNICATION PROTOCOL
10.1 Interfaces
RS485: asynchronous, half-duplex.
Default: 8-E-1, 19200bps. See Group PC parameter settings.
10.2 Communication Modes
10.2.1 The protocol is Modbus protocol. Besides the common register Read/Write operation, it is supplemented with commands of follows: parameters management.
10.2.2 The drive is a slave in the network. It communicates in ‘point to point’ master-slave mode. It will not respond to the command sent by the master via broadcast address.
10.2.3 In the case of multi-drive communication or long-distance transmission, connecting a 100~120 Ω resistor in parallel with the master signal line will help to enhance the immunity to interference.
10.3 Protocol Format
Modbus protocol supports both RTU and ASCII mode. The frame format is illustrated as
Modbus adopts “Big Endian” representation for data frame. This means that when a numerical quantity larger than a byte is transmitted, the most significant byte is sent first.
RTU mode
In RTU mode, the Modbus minimum idle time between frames should be no less than 3.5 bytes. The checksum adopts CRC-16 method. All data except checksum itself sent will be counted into the calculation. Please refer to section: CRC Check for more information.
Note that at least 3.5 bytes of Modbus idle time should be kept and the start and end idle time need not be summed up to it.
The table below shows the data frame of reading parameter 002 from slave node address
1.
108
Communication Protocol
Read No. CRC Node addr. Command Data addr.
The table below shows the reply frame from slave node address 1
Node addr. Command Bytes No.
Data CRC
0x44
ASCII mode
In ASCII mode, the frame head is “0x3A”, and default frame tail is “0x0D” or “0x0A”. The frame tail can also be configured by users. Except frame head and tail, other bytes will be sent as two ASCII characters, first sending higher nibble and then lower nibble. The data have 7/8 bits. “A”~“F” corresponds to the ASCII code of respective capital letter. LRC check is used. LRC is calculated by adding all the successive bytes of the message except the head and tail, discarding any carriers, and then two’s complementing the result.
Example of Modbus data frame in ASCII mode:
The command frame of writing 0x0003 into address “0x1000” of slave node address 1 is shown in the table below:
LRC checksum = the complement of (01+06+10+00+0x00+0x03) = 0xE5

Node addr. Command Data addr.
Data to write LRC Frame tail
0 0 0 3 E 5 CR
30 30 30 33 45 35 0D
LF
0A
10.4 Protocol function
Different respond delay can be set through drive’s parameters to adapt to different needs.
For RTU mode, the respond delay should be no less than 3.5 bytes interval, and for
ASCII mode, no less than 1ms.
The main function of Modbus is to read and write parameters. The Modbus protocol supports the following commands:
0x03 Read inverter’s function parameter and status parameters
0x06 Write single function parameter or command parameter to inverter
All drive’s function parameters, control and status parameters are mapped to Modbus
R/W data address.
The data addresses of each function parameters please refer the sixth column of chapter

The above shows the format of the frame. Now we will introduce the Modbus command and data structure in details, which is called protocol data unit for simplicity. Also MSB stands for the most significant byte and LSB stands for the least significant byte for the same reason. The description below is data format in RTU mode. The length of data unit in ASCII mode should be doubled.

If the command is reading the type of inverter (data address 0x3016), the content value in reply message is the device code:
The high 8 bit of device code is the type of the inverter, and the low 8 bit of device code is the sub type of inverter.

If the operation fails, the inverter will reply a message formed by failure command and error code. The failure command is (Command ＋ 0x80). The error code indicates the reason of the error; see the table below.
Value Name
01H
02H
Illegal command
Illegal data address.
Mean
The command from master can not be executed. The reason maybe:
1. This command is only for new version and this version can not realize.
2. Slave is in fault status and can not execute it.
Some of the operation addresses are invalid or not allowed to access.
When there are invalid data in the message framed received by slave.
06H
10H write exceed the range, but indicate the message frame is a illegal frame.
Slave busy Inverter is busy(EEPROM is storing)
Password error
The password written to the password check address is not same as the password set by P7.00.
12H
13H
Written not allowed.
System locked
It only happen in write command, the reason maybe:
1. the data to write exceed the range of according parameter
2. The parameter should not be modified now.
3. The terminal has already been used.
When password protection take effect and user does not unlock it, write/read the function parameter will return this error.

If the operation fails, the inverter will reply a message formed by failure command and error code. The failure command is (Command ＋ 0x80). The error code indicates the reason of the error; see table 1.
10.5 Note:
10.5.1 Between frames, the span should not less than 3.5 bytes interval, otherwise, the message will be discarded.
10.5.2 Be cautious to modify the parameters of PC group through communication, otherwise may cause the communication interrupted.
10.5.3 In the same frame, if the span between two .near bytes more than 1.5 bytes interval, the behind bytes will be assumed as the start of next message so that communication will failure.
10.6 CRC Check
For higher speed, CRC-16 uses tables. The following are C language source code for
CRC-16. unsigned int crc_cal_value(unsigned char *data_value,unsigned char data_length)
{ int i; unsigned int crc_value=0xffff; while(data_length--)
{ crc_value^=*data_value++; for(i=0;i<8;i++)
{ if(crc_value&0x0001)crc_value=(crc_value>>1)^0xa001;
} else crc_value=crc_value>>1;
} return(crc_value);
