7.6

Soft Torque

Principle of operation of Soft Torque during starting

The Soft Torque function reduces the drive acceleration rate shortly before the motor

reaches its rated speed. This produces an almost linear speed curve. This helps to ensure

smooth movement of a conveyor belt, for example, and so prevent fragile goods on the belt

from tipping over.
