Use this parameter to set the maximum time for a stall stage.
This parameter is the maximum time for the stall stage to be active before a motor stall fault occurs. The value of this parameter can
be set between 1.0 s and 120.0 s. An internal counter counts the stall time. If the stall time counter value goes above this limit, the
protection causes the drive to trip.
