Corrective Actions
1. Press RESET key to set all parameters to
factory setting.

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.
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)
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.
1. Check the RS485 connection between the AC
motor drive and RS485 master for loose wires
and wiring to correct pins.
2. Check if the communication protocol, address,
transmission speed, etc. are properly set.
3. Use the correct checksum calculation.
4. Please refer to group 9 in the chapter 5 for
detail information (User manual on cd-rom).
Please contact the Gefran Technical Assistance.
Check the wiring of ACI
Check Power Source Input if all 3 input phases are
connected without loose contacts.
1. Check cabling between drive and motor
2. Retry again
