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
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
In order to prevent the rectifier damage result from the large current, AC reactor should
24
25
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
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
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.
26
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:
27
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
2 ). 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.
30
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.
31
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
32
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. z EN61000-6-4 z EN61000-6-3 z EN61800-3

5.2 Operation Process
5.2.1 Parameter setting
Three levels of menu are: 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.
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:
36
Operation 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 Shortcut menu setting
Shortcut menu, in which parameters in common use can be programmed, provides a quick way to view and modify function parameters. In the shortcut menu, a parameter being displayed as “hP0.11” means the function parameter P0.11. Modifying parameters in the shortcut menu has the same effect as doing at normal programming status.
Maximum 16 function parameters can be saved into the shortcut menu, and these parameters can be added or deleted when P7.03 is set to be 0.
5.2.3 Shortcut menu operation
Shortcut menu has two levels of menus, which are corresponding to the second-level and the third-level menus of general menu, and has no corresponding with first-level menu.
Remarks:
In stop or running status, press QUICK/JOG to enter the shortcut first-level menu, use
UP/DOWN to select different shortcut parameter, and then press DATA/ENT to enter the shortcut second-level menu. The method to modify parameter at the shortcut second-level menu is the same as that at the general third-level menu. If want to return to last display, press QUICK/JOG.
The operation example is as following:

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

~ 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 p
and integral time K i 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 p
and K
I
are proportional to the bias between
P3.02 and P3.05. For details, please refer to following figure.

Detailed Function Description
The system's dynamic response can be faster if the proportion gain K p
is increased;
However, if K p
is too large, the system tends to oscillate.
The system dynamic response can be faster if the integral time K i
is decreased;
However, if K i
is too small, the system becomes overshoot and tends to oscillate.
P3.00 and P3.01 are corresponding to K p
and K i
at low frequency, while P3.03 and P3.04 are corresponding to K p
and K i
at high frequency. Please adjust these parameters according to actual situation. The adjustment procedure is as follow:
1. Increase the proportional gain (K p
) as far as possible without creating oscillation.
2. Reduce the integral time (K i
) as far as possible without creating oscillation.
For more details about fine adjustment, please refer to description of P9 group.

0 : Torque control is disabled. Inverter will run at speed control mode. Output torque of inverter which should not greater than torque limit (P3.14) matches the torque of load automatically. When the torque of load is greater than torque limit, output torque will remain as torque limit and output frequency will decrease automatically.
1~8: Torque control is enabled. z When torque control takes effect, if Tset > Tload, output frequency will increase continuously until it reaches upper frequency limit.
If Tset < Tload, output frequency will decrease continuously until it reaches lower frequency limit.
Inverter can run at any frequency between upper and lower frequency limit only when Tset = Tload. z Torque control can be switched to speed control, vice versa.
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 speed control automatically. z If torque setting is positive, inverter will run forward; otherwise it will run reverse.

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
P3.14=90%, then
Actual torque setting = 80% (P3.13) * 90% (P3.14) = 72%.

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: This value 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 0, the inverter will boost the output torque according to the load automatically. Please refer to following diagram.

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.

If PB.08 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.07. The inverter can continue to run without tripping by reducing its output frequency and feedback energy via motor.
Notice: If PB.08 is too big, the feedback energy of motor will be too large and may cause over-voltage fault. If PB.08 is too small, the feedback energy of motor will be too small to achieve voltage compensation effect. So please set PB.08 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.10, the inverter will stop reducing its output frequency. When DC bus voltage become lower than PB.10, the deceleration continues, as shown in following figure.

During acceleration of inverter, the actual motor speed rise rate may lower than the output frequency rise rate because of too big load. If no measures to take, inverter will trip caused by over-current.
The principle of over-current protection is to detect the output current of inverter during inverter operation and compare it with over-current stall threshold determined by PB.12.
If it exceeds the value of PB.12 during acceleration, inverter will remain output frequency; if it exceeds the value of PB.12 during constant speed running, inverter will decrease output frequency. When output current of inverter is lower than the value of PB.12, inverter will continue to accelerate until output frequency reach frequency reference.

Inverter may have following faults or malfunctions during operation, please refer to the following solutions.
No display after power on: z Inspect whether the voltage of power supply is the same as the inverter rated voltage or not with multi-meter. If the power supply has problem, inspect and solve it. z Inspect whether the three-phase rectify bridge is in good condition or not. If the rectification bridge is burst out, ask for support. z Check the CHARGE light. If the light is off, the fault is mainly in the rectify bridge or the buffer resistor. If the light is on, the fault may be lies in the switching power supply. Please ask for support.
Power supply air switch trips off when power on: z Inspect whether the input power supply is grounded or short circuit. Please solve the problem. z Inspect whether the rectify bridge has been burnt or not. If it is damaged, ask for support.
Motor doesn’t move after inverter running: z Inspect if there is balanced three-phase output among U, V, W. If yes, then motor could be damaged, or mechanically locked. Please solve it. z If the output is unbalanced or lost, the inverter drive board or the output module may be damaged, ask for support..
Inverter displays normally when power on, but switch at the input side trips when running: z Inspect whether the output side of inverter is short circuit. If yes, ask for support. z Inspect whether ground fault exists. If yes, solve it. z If trip happens occasionally and the distance between motor and inverter is too far, it is recommended to install output AC reactor.

Maintenance
8.2 Periodic Maintenance
Customer should check the drive every 3 months or 6 months according to the actual environment
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.
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.
