6-1 Common Problems and Solutions
Following fault name will only be displayed when using the digital keypad.
Display Description Corrective Actions
Over-current during
acceleration
(Output current exceeds triple
rated current during
acceleration.)
1. Short-circuit at motor output: Check for
possible poor insulation at the output.
2. Acceleration Time too short: Increase
the Acceleration Time.
3. AC motor drive output power is too
small: Replace the AC motor drive with
the next higher power model.
Over-current during
deceleration
(Output current exceeds triple
rated current during
deceleration.)
1. Short-circuit at motor output: Check for
possible poor insulation at the output.
2. Deceleration Time too short: Increase
the Deceleration Time.
3. AC motor drive output power is too
small: Replace the AC motor drive with
the next higher power model.
Over-current during steady
state operation
(Output current exceeds triple
rated current during constant
speed.)
1. Short-circuit at motor output: Check for
possible poor insulation at the output.
2. Check if motor is jammed.
3. AC motor drive output power is too
small: Replace the AC motor drive with
the next higher power model.
Short-circuit is detected
between upper bridge and
lower bridge of the IGBT
module
Return to the factory
Hardware failure in current
detection Over current occur at
STOP
Return to the factory
DC BUS over-voltage during
acceleration (230V: DC 450V)
DC BUS over-voltage during
deceleration (230V: DC 405V)
DC BUS over-voltage at
constant speed (230V: DC
405V)
1. Check if the input voltage falls within
the rated AC motor drive input voltage
range.
2. Check for possible voltage transients.
3.
If DC BUS over-voltage due to
regenerative voltage, please increase the
Deceleration Time or add an optional brake
resistor.
