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.

These parameters determine sleep functions of the AC drive. If the command frequency falls
below the sleep frequency, for the specified time in Pr. 08-12, then the drive will shut off the
output and wait until the command frequency rises above Pr. 08-11. Please see the below
diagram.
