Functions:
- Deceleration (reduction in pressure surges), protection against underload or reversal of phase rotation direction
- Control of pump priming and the pump’s direction of rotation
- Monitoring of overloads for incident detection or underloads for break detection
- Braking for fast stop
- Torque control on starting
