44..77..44..11 Soft Stop Parameters
The ASTAT-BP incorporates 5 stopping curves that enable you to select the suitable torque curve
Soft Stop Curve 0 – Standard Curve (Default) – voltage is linearly reduced from nominal to zero.
The most stable and suitable curve for preventing prolonged stopping and motor overheating.
Soft Stop Curves 1, 2, 3 Pump Control – In some pump applications, when pumping to higher
elevation a considerable part of the torque is constant and does not decrease with speed.
