Process Data
The process data fields are used to control the drive (e.g.,
Run, Stop, Reference, Fault Reset) and to quickly read actual
values (e.g., Output frequency, Output current, Fault code).
The fields are structured as follows.

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 Reference (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.
