6.4 Solutions for Simple Fault during Commissioning
Simple faults during commissioning Solutions
Over current occurs during acceleration (O.C.-2) Increase the acceleration time
Over voltage occurs during deceleration (O.E.-3) Increase the deceleration time
Over current occurs immediately after pressing the <Run>
key (O.C.-2)
Incorrect wiring. Check if U, V, W outputs of the main circuit
are shorted or grounded
The motor runs in the direction opposite to the desired one Change the sequence of any two phases of U, V and W
The motor vibrates and runs in uncertain directions after
each starting
One phase of U, V and W is disconnected (output phase
loss)

6.5 Notes on Frequent Start and Stop
1. Do not use the electromagnetic contactor KM connected prior to termi‐
nals L1, L2 and L3 to start or stop the motor to avoid early aging and
damage of the filter capacitor. External terminals FWD, REV and
X1...X8 may be used to start and stop the frequency converter.
2. The current limiting resistor for capacitor charging may be damaged due
to frequent start and stop of the motor with the electromagnetic contac‐
tor KM connected prior terminals L1, L2 and L3.
