1. The lead from frequency inverter to motor
is disconnected.
2. The driving or control panel of the
frequency inverter is faulty.
3. The three-phase winding of the motor is
faulty.
1. Eliminate peripheral failures.
2. Seek for manufacturer’s support.
3. Eliminate the failure of motor.

input voltage is
unbalanced
(can be shielded)
The imbalance rate of three-phase voltage is
larger.
1. Add AC or DC reactor.
2. Increase the capacity of frequency
inverter.
