Inverter and Peripheral Device Connection
Figure 2.1 Inverter and Peripheral Device Connection Diagram
Note: The diagram is drawn taking a three-phase power input as an example.
1、Inverter input side
DC reactor: Improve the power factor of power supply at the input side and reduce the high harmonic current; a
built-in DC reactor of the ≥37kW inverters.
AC reactor: Improve the power factor of power supply at the input side and reduce the high harmonic current.
Inverter-specific filter: suppress high-frequency noise interference from the inverter.

2、Inverter output side
Inverter-specific filter: suppress high-frequency noise interference from the inverter.
AC reactor: If the wiring between the inverter and the motor is too long, the high-order harmonic current leakage
will increase due to the influence of the distributed capacitance of the wire, which may cause the inverter to
activate output over-current protection. Therefore, the wiring length between the inverter and the motor should
not exceed 100m. If the wiring length exceeds 100m, the reactor and output filter should be optionally
configured.
Do not connect a capacitor or a surge filter to the output side of the inverter. The inverter outputs high order
harmonics, so connecting the capacitor or surge filter to the output side may overheat and damage the inverter.
Figure 2.2 Inverter output side error connection
3、Braking resistor
Inverters of ≤30kW come with a built-in braking unit as a standard, and an external braking resistor; Inverters
of >30kW feature an optional external braking unit. An external braking resistor can be connected. It is
necessary to fully consider heat dissipation conditions of the braking resistor, and ensure that it is well ventilated.
Wiring length of the braking resistor must not exceed 5m.
4、Grounding
The grounding terminal is preferably a dedicated grounding electrode with a impedance of 10 Ω or less. Do not
share with welding machines or other power equipment. Use the grounding wire specified in the electrical
equipment technical standard, and keep it as short as possible. If the grounding wire is too long, leakage
current of the inverter will make the potential of grounding terminal unstable. It is recommended to use a special
yellow-green grounding wire. See the table below for the grounding wire specifications. When multiple inverters
are grounded, it is recommended to avoid forming loops so as to avoid circuits formed by grounding wires.

2. Inverter commissioning steps after power up
1. Confirm the rated power P96.00, the rated current P96.01, and the rated voltage P96.03 of the
inverter are the same as the actual parameters on the nameplate.
2. At first on-site commissioning, first perform factory reset. Parameter processing Init = 7 Select Y
to perform factory reset.
3. Monitor status to see if Udc is around 540V.
4. Confirm whether the controlled motor is an asynchronous motor. Parameters on the motor
nameplate include: rated power, rated voltage, rated current, rated frequency, rated speed,
number of motor poles and slip. Write these data into the corresponding parameters of the P20
group.
Slip calculation fs=(synchronous speed - rated speed)*number of motor pole pairs/60
For example, motor nameplate parameters: rated frequency 50Hz, 4 poles, rated speed 1470rpm,
the slip frequency is fs=(1500-1470)*2/60=1Hz.

frequency
0: Run according to the limit frequency 1: Stop
2: Set frequency is 0
Note: In some cases, the running command is always maintained. When the motor speed is lower than
a certain frequency, the inverter output voltage is zero. At this time, set P70.01=0.50Hz (if it is lower than
0.5Hz), P70.22 =1; that is, when the output frequency is lower than 0.5Hz, the inverter stops, and when
output frequency is above 0.5Hz, the inverter is started.
2. Analog input description
When the analog input function is selected as for target speed setting, 10V corresponds to the set speed
reference value P20.13 (maximum frequency of motor 1). For example, when P20.13=50.00Hz, if you
input 10V, set speed is 50Hz, if you input 5V, set speed is 25 Hz, and so on.
3. Analog output description
Analog output is 0~5V, corresponding to 0~100% rated value (such as rated speed, rated current, etc.), if
you want 0~100% rated value (such as rated speed, rated current, etc.), and the corresponding output is
0~10V, you can set the output P33.02 or P33.05.
4. Speed tracking start
To select this function, you need to set P11.00=2, and set the P11.14 parameter value.

5. Inverter test run process
1. Motor no-load test run
Check if the motor is in no-load state (disconnect from the machine)
For the first test run, the set frequency should not be too large, 5Hz is enough .
Check if the motor running direction is consistent with the set one?
Check if the motor acceleration and deceleration are smooth, with no abnormal sound
During test running, the actual current Irms is approximately 30% of the rated current of
motor
The output voltage value Uout is substantially linear with the current frequency value Vref
2. Motor loaded test run
Check if the motor is connected to mechanical equipment and confirm the safety of motor
and mechanical equipment
When loaded running starts, be ready to press the STOP button (if there is an abnormality)
Check if the load running direction is consistent with the set direction on the inverter?
Check if the motor acceleration and deceleration are smooth during running with load
Check if the actual motor current Irms is too large
Check if there is an abnormal sound or current oscillation when load frequency changes.

Set value
P61.06
U/F control current loop
Max
Generally set to the default value; When P10.00=0
is active, current oscillation occurs, adjust this value
(change 0.2% for each time)
P61.07
U/F control current loop
Min
Generally set to default value; When P10.00=0 is
active, current oscillation occurs, adjust this value
(change 0.2% for each time)
2. High-performance VF control refers to P10.00 = 5 control mode. If the motor with heavy load
fails to start due to over-current, you can try to adjust the following parameters. See the table
below for details.
Parameter no.
Name
Set value
P71.35
SVC1 inertia coefficient
Generally set to default value; When P10.00=5 is
active, motor starts with heavy load, this value can
be increased; do not exceed 200% when setting
P71.36
SVC1 low speed torque
boosting
Generally set to default value; When P10.00=5 is
active, motor starts with heavy load, this value can
be increased; generally set to 150%~200%
3. If it is found that the motor noise is large at running, appropriately increase the PWM carrier
frequency value (P71.14 parameter) under the condition that the inverter does not report fault.
