Ramp DOWN Time
10 SEC.
1–30 32 Sec. Sets Ramp DOWN Time of the motor.
Used for controlled deceleration of high friction loads.
Determines the motor’s voltage ramp down time.
Note:
When the ASTAT-XT operates with a bypass
contactor, the bypass contactor can be controlled by
the ASTAT-XT’s End of Ramp relay.
Upon soft stop initiation the End of Ramp relay is de-
energized, the load is transferred to the ASTAT-XT, and
voltage begins ramping down.
End Torque
0 (MIN.)
0 (MIN.) – 10 (MAX.) Sets End Torque during soft stop.
Determines torque towards the end of a soft stop.
If the current still flows after speed is softly reduced to
zero, you should increase the End Torque setting.
