6. 6 V5 Softstarter CDP – DYNAMIC TORQUE CONTROL 2. FURTHER ADVANTAGES » V5 series incorporates a “Dynamic Torque Control”, exclusive to Power Electronics, this ensures a soft and progressive start even in applications with a high moment of inertia. » Using this control algorithm achieves linear acceleration and an optimization of peak currents during starting.

7. 7 V5 Softstarter CDP – DYNAMIC TORQUE CONTROL 2. FURTHER ADVANTAGES DYNAMIC TORQUE CONTROL: » Torque automatically adjusts to suit any load type, not necessarily linear or quadratic, other types are suitable. » Torque automatically increases as the softstarter can detect when the motor is not accelerating. » If acceleration continues the soft starter will automatically maintain torque levels. » The softstarter can self-adjust ramp times to suit any torque / load profile. » In no situation will the softstarter provide more torque than is needed. This minimises any energy loss during start.

13. 13 DYNAMIC TORQUE CONTROL: Control algorithm. The control algorithm is designed for monitoring motor speed. Using motor speed data, softstarter controls output voltage applied to the motor in order to increase, decrease or keep constant the motor torque. V5 Softstarter CDP – DYNAMIC TORQUE CONTROL 5.
