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.
Table 49. Process Data Slave
R
Master (max. 22 bytes)
Table 50. Process Data Master R Slave (max. 22 bytes)
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.
Process Data In
This register range is reserved for the control of the VFD.
Process Data In is located in range ID 2001–2099. The
registers are updated every 10 ms. See table below.
Table 51. Fieldbus Basic Input Table
Control Word
PowerXL DG1 drive uses 16 bits as shown below. These bits
are application specific.

1 Not for use.
2 Net Ref.
3 Net Cntrl.
Table 53. Speed Reference
This is the Reference 1 to the VFD. Used normally as Speed
reference.
Process Data In 1 to 8
Process Data In values 1 to 8 can be used in applications for
various purposes.
