4.4.1 Setpoint inversion
[4-3] Setpoint inversion (schematic diagram)
Via the digital input DI3 the effective direction of the (bipolar) setpoint can be inverted, if
required.
r Parameter setting: All parameters tab  category Actuator - torque  Multiplexer
4.4.2 Ramp generator
[4-4] Ramp generator (schematic diagram)
In order to avoid setpoint step-changes the torque setpoint passes a ramp generator with
a parameterisable acceleration/deceleration and S-ramp time before it is transmitted to
the basic drive function "Torque follower".
