The speed−controlled operation (profile velocity mode) comprises the following
subfunctions:

ƒ Speed detection via angle encoder by differentiation
ƒ Speed control with appropriate input and output signals
ƒ Limitation of torque setpoint (torque_demand_value)
ƒ Monitoring of actual speed (velocity_actual_value) with window
function/threshold
The meaning of the parameters profile_acceleration, profile_deceleration and quick_stop
