The Soft Stop option can be used in applications requiring an
extended coast-to-rest. The voltage ramp down time is use
adjustable from 0 to 60 seconds. The Soft Stop time is adjusted
independently from the start time. The load will stop when the
voltage drops to a point where the load torque is greater than th
motor torque.
