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

Wiring

power supply.

4.5.1.3 AC reactor

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.

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

). 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.

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

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,

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.

4.7.3.1 Noise control

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.

4.7.3.2 Site wiring

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

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.

4.7.3.4 Leakage Current

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.

4.7.3.5 EMC Filter

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

Wiring

power filter.

z Function code group (first-level); z Function code (second-level); z Function code value (third-level).

Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-class menu from the third-class menu. The difference is: pressing DATA/ENT will save the set parameters into the control panel, and then return to the second-class menu with shifting to the next function code automatically; while pressing PRG/ESC will directly return to the second-class menu without saving the parameters, and keep staying at the current function code

Operation

Figure 5.2 Flow chart of parameter setting.

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:

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.

In stop status, there are nine parameters which can be chosen to display or not. They are:

reference frequency, DC bus voltage, ON-OFF input status, open collector output status,

PID setting, PID feedback, analog input AI1 voltage, analog input AI2 voltage, step

number of multi-step speed. Whether or not to display can be decided by setting the corresponding binary bit of P7.07. Press the 》/SHIFT to scroll through the parameters in

right order . Press DATA/ENT + QUICK/JOG to scroll through the parameters in left

order.

frequency, DC bus voltage, output voltage, output current, output power, output torque,

PID setting, PID feedback, ON-OFF input status, open collector output status, length

value, count value, step number of PLC and multi-step speed, voltage of AI1, voltage of

AI2 and step number of multi-step speed. Whether or not to display can be decided by the

Operation

bit option of Function Code P7.06 (converted into binary system). Press the 》/SHIFT to

scroll through the parameters in right order . Press DATA/ENT + QUICK/JOG to scroll

Acceleration time is the time of accelerating from 0Hz to maximum frequency (P0.04).

Deceleration time is the time of decelerating from maximum frequency (P0.04) to 0Hz.

Please refer to following figure.

Detailed Function Description

Figure 6.1 Acceleration and deceleration time.

When the reference frequency is equal to the maximum frequency, the actual

acceleration and deceleration time will be equal to the P0.08 and P0.09 respectively.

When the reference frequency is less than the maximum frequency, the actual

acceleration and deceleration time will be less than the P0.08 and P0.09 respectively.

The actual acceleration (deceleration) time = P0.08 (P0.09) * reference frequency/P0.04.

CHE series inverter has 2 groups of acceleration and deceleration time.

1st group: P0.07, P0.08

2nd group: P8.00, P8.01

The acceleration and deceleration time can be selected by combination of multifunctional

Carrier frequency will affect the noise of motor and the EMI of inverter.

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

The system dynamic response can be faster if the integral time K

is decreased;

However, if K

is too small, the system becomes overshoot and tends to oscillate.

P3.00 and P3.01 are corresponding to K

and Ki at low frequency, while P3.03 and P3.04

are corresponding to K

and Ki at high frequency. Please adjust these parameters

according to actual situation. The adjustment procedure is as follow:

 Increase the proportional gain (K

) as far as possible without creating oscillation.

 Reduce the integral time (K

) as far as possible without creating oscillation.

Torque boost will take effect when output frequency is less than cut-off frequency of

torque boost (P4.02). Torque boost can improve the torque performance of V/F control at

low speed.

The value of torque boost should be determined by the load. The heavier the load, the

larger the value.

Notice: P4.01 should not be too large, otherwise the motor would be over-heat or

the inverter would be tripped by over-current or over-load.

If P4.01 is set to be 0, the inverter will boost the output torque according to the load

PID control is a common used method in process control, such as flow, pressure and

temperature control. The principle is firstly detect the bias between preset value and

feedback value, then calculate output frequency of inverter according to proportional gain,

integral and differential time. Please refer to following figure.

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 overshooting

If overshooting occurs, shorten the differential time and lengthen the integral time.

Figure 6.21 Reducing overshooting diagram.

z Rapidly stabilizing control status

To rapidly stabilize the control conditions even when overshooting occurs, shorten the

integral time and lengthen the differential time.

Detailed Function Description

Figure 6.22 Rapidly stabilizing diagram.

z Reducing long-cycle oscillation

If oscillation occurs with a longer cycle than the integral time setting, it means that integral

operation is strong. The oscillation will be reduced as the integral time is lengthened.

Figure 6.23 Reducing long-cycle oscillation diagram.

z Reducing short-cycle oscillation

If the oscillation cycle is short and oscillation occurs with a cycle approximately the same

as the differential time setting, it means that the differential operation is strong. The

oscillation will be reduced as the differential time is shortened.

Figure 6.24 Reducing short-cycle oscillation diagram.

If oscillation cannot be reduced even by setting the differential time to 0, then either lower

the proportional gain or raise the PID primary delay time constant.

Sampling cycle T refers to the sampling cycle of feedback value. The PI regulator

calculates once in each sampling cycle. The bigger the sampling cycle, the slower the

response is.

Bias limit defines the maximum bias between the feedback and the preset. PID stops

operation when the bias is within this range. Setting this parameter correctly is helpful to

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

8.2 Periodic Maintenance

Customer should check the drive every 3 months or 6 months according to the actual

Maintenance

environment

8.2.1 Check whether the screws of control terminals are loose. If so, tighten them with a

screwdriver;

8.2.2 Check whether the main circuit terminals are properly connected; whether the

mains cables are over heated;

8.2.3 Check whether the power cables and control cables are damaged, check

especially for any wear on the cable tube;

8.2.4 Check whether the insulating tapes around the cable lugs are stripped;

8.2.5 Clean the dust on PCBs and air ducts with a vacuum cleaner;

8.2.6 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.

8.2.7 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.

8.2.8 Before the insulation test of the motor, disconnect the motor from the drive to

avoid damaging it.

8.3 Replacement of wearing parts

Fans and electrolytic capacitors are wearing part, please make periodic replacement to

ensure long term, safety and failure-free operation. The replacement periods are as

follows:

◆Fan: Must be replaced when using up to 20,000 hours;

◆Electrolytic Capacitor: Must be replaced when using up to 30,000~40, 000 hours.

8.4 Warranty

The manufacturer warrants its products for a period of 12 months from the date of

purchase.
