4. Faults and Analysis
(1) When RUN key is pressed, the motor does not run.
1) The setting of operation mode is wrong, i.e., under the operation mode of
external control terminals, the inverter is started by the digital operator or
under the operation mode of the digital operator it is started by the external
control terminals.
2) The frequency reference is too low or not set.
3) The peripheral wiring is wrong. For example, the setting of wiring of two-
wire system and three-wire system and other related parameters have errors.
4) The setting of multi-f unction terminals is wrong (in the external control).
5) The inverter is in the fault protection.
6) The motor fails.
7) The inverter fails.
(2) The parameters cannot be set.
1) Password locks. Please decrypt it first before resetting.
2) The inverter is in running.
3) The connection of the connecting parts is abnormal. The communication of
the digital operator is abnormal. Take out the operator after power-off and
then mount it again for a trial.
(3) The motor cannot rotate reverse.
Reverse rotation is disabled.
(4) The motor rotates in the opposite direction.
The output line is wrongly connected. Please change any two lines of U.V.W
over.
(5) The deceleration of the motor is too slow.
1) The setting of Ramp-down Time is too long. Decrease Ramp-down Time.
2) Add a braking resistor.
3) Add a DC brake.
(6) Over-heat of the motor
1) The load is too large. The actual torque has exceeded the rated torque of the
motor. It is recommended to increase the capacity of the motor.
2) The ambient temperature is too high. In a place with higher temperature the
motor will be burn out. Please decrease the temperature around the motor.
3) The phase to phase withstand voltage of the motor is insufficient.
The switch actions of the inverter will make the winding coil of the motor
produce shock wave. Typically the maximum shock voltage will reach 3
times that of input power of the inverter. Please select a motor with higher
