Fault
Name
Fault Descriptions Corrective Actions
Software protection failure Return to the factory.
Password is locked.
Keypad will be locked. Turn the power ON after
power OFF to re-enter the correct password. See
Pr.0-07 and 0-08.
Analog feedback error or
ACI open circuit
1. Check parameter setting (Pr.A-00) and
AVI/ACI wiring
2. Check for possible fault between system
response time and the feedback signal
detection time (Pr.A-08).
Phase Loss Check input phase wiring for loose contacts.
PID feedback error
1. Check PID feedback wiring.
2. Check if the parameter setting is properly set.
6.2 Reset
There are three methods to reset the AC motor drive after solving the fault:
1. Press
STOP/RESET
key on keypad.
2. Set external terminal to “RESET” (set one of Pr.4-04~Pr.4-08 to 06) and then set to be
ON.
3. Send “RESET” command by communication.
NOTE
Make sure that RUN command or signal is OFF before executing RESET to prevent damage or
personal injury due to immediate operation.
