Over-current during
deceleration
1. Short-circuit at motor output: Check for possible
poor insulation at the output line.
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
1. Short-circuit at motor output: Check for possible
poor insulation at the output line.
2. Sudden increase in motor loading: Check for
possible motor stall.
3. AC motor drive output power is too small:
Replace the AC motor drive with the next
higher power model.

Ground fault
When (one of) the output terminal(s) is grounded,
short circuit current is more than 50% of AC motor
drive rated current, the AC motor drive power
module may be damaged.
NOTE: The short circuit protection is provided
for AC motor drive protection, not for protection
of the user.
1. Check whether the IGBT power module is
damaged.
2. Check for possible poor insulation at the output
line.
PID feedback signal error
1. Check parameter settings (Pr.10.01) and
AVI/ACI wiring.
2. Check for possible fault between system
response time and the PID feedback signal
detection time (Pr.10.08)
Auto accel/decel failure
1. Check if the motor is suitable for operation by
AC motor drive.
2. Check if the regenerative energy is too large.
3. Load may have changed suddenly.
