The frequency/speed control application essentially influences speed
interpretation in the process image and the evaluation of Rotary_Axis_Period.
Otherwise, the complete functions of other modes, such as Jog mode,
Referencing, Move task via mailbox and Program mode can be utilized.

The function of the bits in control bytes C1 ... C3 and in status bytes S1 … S3
are determined by the Frequency/Speed control application. When switchover
is made to this application, the linked locations for the old application are
retained. The meaning of the bits for the standard configuration are explained
below.
