8.2.4.3 FINAL TORQUE During Soft-Stopping a Pump Motor
While decelerating, the check valve may close before DECELERATION TIME has elapsed, thus allowing
current to flow through stator winding causing unnecessary heat. Select FINAL TORQUE sensitivity to 1 and
stop the pump, then confirm that the current stopped flowing through the motor shortly after the check valve
closed.
If current still flows more than 3-5 seconds after check valve closure, increase FINAL TORQUE (up to a
maximum value of 10) to stop current flow earlier.
