Setpoint/actual value assignments are freely selectable, which means, for
example, that the speed setpoint can be given in the task telegram in the
PZD2, while the actual speed value can be returned in the reply telegram in
the PZD2 (technologically useful). Or another actual value can be returned,
such as actual torque value, actual position value or actual current value.
