Solutions for Simple Faults during Commissioning

Simple faults
Over current (OC-1 or OC-2) occurs dur‐
ing acceleration
Over voltage (OE-3) occurs during decel‐
eration
Over current (SC, OC-1 or OC-2) occurs
immediately after pressing the Run key
The motor runs in the direction opposite to
expected
The motor vibrates and runs in uncertain
directions after each starting

Solutions
Increase the acceleration time
Increase the deceleration time
Incorrect wiring. Check if U, V, W outputs
of the main circuit are shorted or grounded
Change the sequence of any two phases
of U, V and W
One phase of U, V and W is disconnected
(output phase loss)
