Over current
Abnormal increase
in current.
1. Check whether the motors horsepower corresponds to the
AC drive output power.
2. Check the wiring connections between the AC drive and
motor for possible short circuits.
3. Increase the Acceleration time.
4. Check for possible excessive loading conditions at the motor.
5. If there are any abnormal conditions when operating the AC
drive after short-circuit being removed, it should be sent back
to manufacturer.
Over voltage
The DC bus voltage
has exceeded its
maximum allowable
value.
1. Check whether the input voltage falls within the rated AC
drive input voltage.
2. Check for possible voltage transients.
3. Bus over-voltage may also be caused by motor regeneration.
Either increase the decel time or add an optional brake
resistor.
4. Check whether the required brake power is within the
specified limits.
