4.4 Wiring Main Circuits
4.4.1 Wiring at input side of main circuit
4.4.1.1 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>.
4.4.1.2 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 power supply.
4.4.1.3 AC reactor In order to prevent the rectifier damage result 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.
4.4.1.4 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.
.18.
CHF100A series high performance universal inverter
Figure4.17 Wiring at input side.
4.4.2 Wiring at inverter side of main circuit
4.4.2.1 DC reactor Inverters from 18.5kW to 90kW have built-in DC reactor which can improve the power factor,
4.4.2.2 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.
Notice: Be sure that the electric polarity of (+) (-) terminals is right; it is not allowed to connect (+) with (-) terminals directly, Otherwise damage or fire may occur.
4.4.3 Wiring at motor side of main circuit
4.4.3.1 Output Reactor Output reator must be installed in the following condition. 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.
4.4.3.2 Output EMC filter
.19.
CHF100A series high performance universal inverter
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 4.18 Wiring at motor side.
4.4.4 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.

Grid
Figure 4.19 Wiring of regenerative unit.
4.4.5 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).
.20.
CHF100A series high performance universal inverter
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:
Figure 4.20 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.
4.4.6 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 (>3.5mm2). When multiple inverters need to be grounded, do not loop the ground wire.
4.5 Wiring Control Circuit
4.5.1 Precautions
4.5.1.1 Use shielded or twisted-pair cables to connect control terminals.
4.5.1.2 Connect the ground terminal (PE) with shield wire.
4.5.1.3 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.

4.6 Installation Guidline to EMC Compliance
4.6.1 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.
.23.
CHF100A series high performance universal inverter
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.
4.6.2 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. At the same time inverter should be designed with certain anti-jamming ability to ensure the smooth working in certain electromagnetic environment. Following is its EMC features:
4.6.2.1 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.
4.6.2.2 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.
4.6.2.3 As the electromagnetic receiver, too strong interference will damage the inverter
and influence the normal using of customers.
4.6.2.4 In the system, EMS and EMI of inverter coexist. Decrease the EMI of inverter can
increase its EMS ability.
4.6.3 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.
4.6.3.1 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
.24.
CHF100A series high performance universal inverter
ground, and the other side should connect to the motor cover. Installing an EMC filter can reduce the electromagnetic noise greatly.
4.6.3.2 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.
4.6.3.3 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.
4.6.3.4 Leakage Current
Leakage current includes line-to-line leakage current and over-ground leakage current.
.25.
CHF100A series high performance universal inverter
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.
4.6.3.5 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:
l Noise filter installed at the input side of inverter; l Install noise isolation for other equipment by means of isolation transformer or
power filter.
4.6.4 The installation complies with the following standard:
l EN61000-6-4: Electromagnetic Interference Detection on the industrial condition. l EN61800-3: Comply with the electromagnetic radiation standard of EN61800-3
(The second environment). Can comply with the electromagnetic radiation standard of EN61000-6-3(residence) and standard of EN61000-6-4.
4.6.5 Notice
l This type of PDS is not intended to be used on a low-voltage public network which supplies domestic premise; l Radio frequency interference is expected if used on such a network.

l 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 parameters autotuning
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:
P2.01: motor rated power. P2.02: motor rated frequency; P2.03: motor rated speed; P2.04: motor rated voltage;
P2.05: motor rated current; Notice: the motor should be uncoupled with its load; otherwise, the motor parameters obtained by autotuning may be not correct. Set P0.16 to be 1, and for the detail process of motor parameter autotuning, please refer to the description of Function Code P0.16. 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.
5.2.4 Password setting

Through P3.00～P3.05, user can set the proportional gain Kp 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 6.6 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, Kp and KI are proportional to the bias between P3.02 and P3.05. For details, please refer to following figure.
Figure 6.7 PI parameter diagram. The system's dynamic response can be faster if the proportion gain Kp is increased; However, if Kp is too large, the system tends to oscillate. The system dynamic response can be faster if the integral time Ki is decreased; However, if Ki is too small, the system becomes overshoot and tends to oscillate. P3.00 and P3.01 are corresponding to Kp and Ki at low frequency, while P3.03 and P3.04 are corresponding to Kp and Ki at high frequency. Please adjust these parameters according to actual situation. The adjustment procedure is as follow:
.48.
CHF100A series high performance universal inverter
u Increase the proportional gain (Kp) as far as possible without creating oscillation. u Reduce the integral time (Ki) 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: 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 be 0, the inverter will boost the output torque according to the load automatically. Please refer to following diagram.

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 (P0.07=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. l Reducing overshooting If overshooting occurs, shorten the differential time and lengthen the integral time.
Figure 6.24 Reducing overshooting diagram. l Rapidly stabilizing control status To rapidly stabilize the control conditions even when overshooting occurs, shorten the integral time and lengthen the differential time. l 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.
CHF100A series high performance universal inverter
.81.
Figure 6.25 Reducing long-cycle oscillation diagram. l 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 6.26 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.

1: For normal motor, the lower the speed is, the poorer the cooling effect is. 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. 2: As the cooling effect of variable frequency motor has nothing to do with running speed, it is not required to adjust the motor overload protection threshold.

If PB.05 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.04. The inverter can continue to run without tripping by reducing its output frequency and feedback energy via motor.
Notice: If PB.05 is too big, the feedback energy of motor will be too large and may cause over-voltage fault. If PB.05 is too small, the feedback energy of motor will be too small to achieve voltage compensation effect. So please set PB.05 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 rise of 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.07, the inverter will stop reducing its output frequency. When DC bus voltage become lower than PB.07, 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.08 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.08 is a percentage of the inverter’s rated current. PB.09 defines the decrease rate of output frequency when this function is active. If PB.08 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. Whether the function is enabled in constant Speed running is determined by PB.10.
Notice: l During auto current limiting process, the inverter’s output frequency may

change; therefore, it is recommended not to enable the function when inverter needs to output stable frequency
l During auto current limiting process, if PB.08 is too low, the overload
capacity will be impacted.
