[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".
