2. The inverters below 18.5KW have build-in braking unit. If need braking, only

need to install braking resistor between PB and (+).

3. For inverters above (including) 18.5KW, if need braking, should install

external braking unit between (+) and (-).

4. +24V connect with PW as default setting. If user need external power supply,

disconnect +24V with PW and connect PW with external power supply.

4. Wire between braking unit and braking resistor should be less than 10m.

5. Braking unit can be used for braking continuously for 5 minutes. When

braking unit is working, temperature of cabinet will be high, user is not allowed to

touch to prevent from injure.

For more details, please refer to DBU and RBU user manual.

4.5 Wiring the Main Circuits

4.5.1 Wiring at the side of power supply

z 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>.

z 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

power supply.

z AC reactor

In order to prevent the rectifier damage result from the large current, AC reactor should

Wiring

be installed at the input side. It can also prevent rectifier from sudden variation of power

voltage or harmonic generated by phase-control load.

z 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.

Figure4.9 Wiring at input side.

4.5.2 Wiring for inverter

z DC reactor

Inverters from 18.5kW to 90kW have built-in DC reactor which can improve the power

factor,

z Braking unit and braking resistor

• Inverters 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 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

z 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.

z Output EMC filter

EMC filter should be installed to minimize the leakage 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 4.10 Wiring at motor side.

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.

Wiring

Figure 4.11 Wiring of regenerative unit.

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. Its detailed wiring is shown in the following

figure:

Wiring

Figure 4.12 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, terminal 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 Circuit Terminals

4.6.1 Precautions

z Use shielded or twisted-pair cables to connect control terminals.

z Connect the ground terminal (PE) with shield wire.

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 knowledge 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 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.

Wiring

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:

z 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.

z 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.

z As the electromagnetic receiver, too strong interference will damage the inverter

and influence the normal using of customers.

z 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,

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.

Wiring

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 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.

4.7.3.2 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

Wiring

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

power filter.

4.7.4 If user install inverter and EMI filter according to the installation guideline, we

believe inverter system comply with following compliance.

Operation

5.2.4 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.

5.2.5 Motor parameter autotune

If “Sensorless Vector Control” or “Vector Control with PG” 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 keypad command as the run command source (P0.01).

And then input following parameters according to the actual motor parameters:

P2.01: motor rated frequency;

P2.02: motor rated speed;

P2.03: motor rated voltage;

P2.04: motor rated current

P2.05: motor rated power.

Notice: the motor should be uncoupled with its load; otherwise, the motor

parameters obtained by autotuning may be not correct.

Set P0.17 to be 1, and for the detail process of motor parameter autotuning, please refer

to the description of Function Code P0.17. And then press RUN on the keypad panel,

the inverter will automatically calculate following parameter of the motor:

P2.06: motor stator resistance;

P2.07: motor rotor resistance;

P2.08: motor stator and rotor inductance;

P2.09: motor stator and rotor mutual inductance;

P2.10: motor current without load;

then motor autotuning is finished.

5.2.6 Password setting

CHV 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, “-----”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.

Notice: Password is not effective for parameters in shortcut menu

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

P3.00～P3.05 are only valid for vector control and torque control and invalid for V/F

control. Through P3.00～P3.05, user can set the proportional gain K

and integral time Ki

of speed regulator (ASR), so as to change the speed response characteristic. ASR's

structure is shown in following figure.

Figure 6.8 ASR diagram.

P3.00 and P3.01 only take effect when output frequency is less than P3.02. P3.03 and

P3.04 only take effect when output frequency is greater than P3.05. When output

frequency is between P3.02 and P3.05, K

and KI are proportional to the bias between

P3.02 and P3.05. For details, please refer to following figure.

Figure 6.9 PI parameter diagram.

Detailed Function Description

The system's dynamic response can be faster if the proportion gain Kp is increased;

However, if K

is too large, the system tends to oscillate.

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:

1. Increase the proportional gain (K

) as far as possible without creating oscillation.

2. Reduce the integral time (K

) as far as possible without creating oscillation.

For more details about fine adjustment, please refer to description of P9 group.

 Switching by multifunctional terminal: For example, if torque setting source is

AI1 (P3.12=2), the value of multifunction terminal S5 is set to 31 (Disable

torque control). When S5 is valid, control mode will switch from torque

control to speed control, vice versa.

 When running at torque control mode, press STOP/RST, it will switch to

Detailed Function Description

Notice:

z When running at torque control mode, the acceleration time has nothing to

do with P0.11.

z The 100% of torque setting is corresponding to 100% of P3.14 (Torque limit).

For example, if torque setting source is keypad (P3.12=1), P3.13=80% and

Detailed Function Description

Optimize the responsiveness by adjusting these parameters while driving an actual load.

Adjusting PID control:

Use the following procedure to activate PID control and then adjust it while monitoring

the response.

1. Enabled PID control (P0.03=6)

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 6.28 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.

Figure 6.29 Rapidly stabilizing diagram.

Detailed Function Description

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 6.30 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 6.31 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.

Detailed Function Description

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

improve the system output accuracy and stability.

When feedback value is less than P9.10 continuously for the period determined by P9.11,

the inverter will alarm feedback lost failure (PIDE).

Notice: 100% of P9.10 is the same as 100% of P9.01.

Detailed Function Description

6.11 PA Group --Simple PLC and Multi-step Speed Control

Simple PLC function can enable the inverter change its output frequency and directions

automatically according to preset running time. For multi-step speed function, the output

frequency can be changed only by multi-step terminals.

Notice:

z Simple PLC has 16 steps which can be selected.

z If P0.03 is set to be 5, 16 steps are available for multi-step speed. Otherwise

only 15 steps are available (step 1~15).
