Fault

Name

Fault Descriptions Corrective Actions

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.

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.

Communication Error

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.

Software protection failure Return to the factory.

Analog signal error Check the wiring of ACI

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)

Phase Loss Check input phase wiring for loose contacts.
