<1> The torque control can only be activated for operation with encoder.
An appropriate fault message is output, if:
1) Sensorless operation is active and closed-loop torque control is requested (r1406.12 = 0 --> 1).
2) Torque control is active and n_act smooth > p1404.
<2> Automatic changeover to sensorless operation, e.g. for extremely high-speed spindle drives.
<3> When the pulses are cancelled, r1509 is set to 0.
