Inverters
⑶
The motor can rotate reversely.
Reverse rotation is forbidden.
⑷
The motor rotatess in the opposite direction.
The output lines have been wrongly connected. Please change
any three lines of U.V.W over.
⑸
The deceloration of the motor is too slow.
①
The setting of Decel Time is too long. Decrease Decel Time.
②
Add a braking resistor.
③
Add a DC brake.
⑹
Overheat of the motor
①
Too big load. The actual torgue has exceeded the rated torgue
of the motor. It is recommended to increase the capacity of
motor.
②
The ambient temperature is too high. In a place with higher
teperaturethe motor will be burn out. Please decrease the
temperature around the motor.
③
The phase to phase withstand voltage of the motor is
insufcient.
The actions of seitches of the inverter will make the winding coil
of tehmotor produce shock wave. Normally the maximum shock
voltage will reach 3 times that of input power supply of the
inverter. Please select a motor with the phase to phase withstand
voltage against shock higher than the maximum shock voltage.
⑺
The starting of the inverter interferes other control devices
①
Lower the carrier frequency and reduce the number of actions
of the internal switches.
②
Install a noice lter on the input side of power supply of the
inverter.
③
Install a noice lter on the output side of the inverter.
④
Make correct grounding for the inverter and the motor.
⑤
Use metal tube to cover the cable to shield it.
⑥
Make separate wiring for the maon circuit wires and control
wires.
