The use of process data depends on the application. In a typical situation, the device is started and
stopped with the ControlWord (CW) written by the Master and the Rotating speed is set with Refer-
ence (REF). With PD1…PD8 the device can be given other reference values (e.g. Torque reference).
With the StatusWord (SW) read by the Master, the status of the device can be seen. Actual Value (ACT)
and PD1…PD8 show the other actual values.
