4.6 Torque follower

[4-8] Basic function "Torque follower" (schematic diagram)

The torque-controlled operation is requested via the digital input DI2. If no other basic

function and error state are active, the torque-controlled operation is enabled.

r The build-up of the defined torque is controlled via a ramp generator based on the

current torque.

r Based on the current motor speed the internal speed limit value is also led to the

setpoint via a ramp generator after the operation is enabled.

r If the enable of the torque-controlled operation is reset via the digital input DI2, the

drive is decelerated to standstill via an independent profile generator of the basic

function "Stop".
