n/a
Resolution:
Suggest to go to the SET menu and set Sty to d (decel). Factory default is set to F (freewheel). The soft stopping by motor torque. The soft start applies torque to the motor in order to decelerate progressively on the dec ramp, avoiding a rapid stop. This type of stop reduces the risk of water hammer on a pump.
Can scroll down to dec and set to around 15-20. Could increase further, if needed.
Could try turning the CLP (drc menu) to off.
