Control
VF VFPG
mode
Settings

This parameter is only valid when the feedback signal is ACI.

This parameter defines the time during which the PID feedback must be abnormal
before a warning 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.

This parameter is only valid when the feedback signal is ACI.

AC motor drive acts when the feedback signals (analog PID feedback or PG (encoder)
feedback) are abnormal.
