Disabled
This parameter defines the time during which the PID feedback must be abnormal before a
warning (see Pr.13.08) is given. It also can be modified according to the system feedback
signal time.
If this parameter is set to 0.0, the system would not detect any abnormality signal.

AC motor drive action when the feedback signals (analog PID feedback or PG (encoder)
feedback) are abnormal.
Setting Pr.13.08 to 0: When the feedback signal fault occurs, it will display “PGEr” on the
digital keypad and the stop to 0Hz by Pr.01.10/Pr.01.12 setting.
Setting Pr.13.08 to 1: When the feedback signal fault occurs, it will display “PGEr” on the
digital keypad and the motor will free run to stop.
Setting Pr.13.08 to 2: When the feedback signal fault occurs, it will display “PGEr” on the
digital keypad and the motor will keep running.
It needs to press “RESET” to clear the warning message “PGEr” displayed on the keypad.
NOTE
The digital keypad is optional. Please refer to Appendix B for details. When using without this optional
keypad, the FAULT LED will be ON once there are fault messages or warning messages from the
external terminals.
