1: Minimum time
With the same situation as in 0, the output frequency precedes and accelerates in minimum time,
even when the stall prevention is active. After release of the mechanical brake, the output current is
retained, and the actual speed of the machinery changes in sync with the output frequency.
This setting can prevent the load from falling, thus improving the response of the inching operation.
