- Ground fault 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

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

Communication
error
No
communication
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
