Note) Decreases of the output frequency are not limited by (Lower limit frequency), and
decrease up to
(Stop frequency)+0.1Hz.
Setting

Function
The function is to decrease or increase the output frequency according to the load
ing condition when the motor torque reaches the limit level.
Setting a torque limit parameter at 250.0 means "Invalid".
