Process Data Out 1 to 8

Process Data Out values 1 to 8 can be used in application for

various purposes. See DG1 application manual for what

these values can be set to.

Process Data OUT (Slave

Master)

The fieldbus master can read the AFD’s actual values using

process data variables. Standard, Pump and Fan Control, PID

control and Multi-Purpose applications use process data as

follows.

Table 58. Process Data OUT

Process Data IN (Master

Slave)

Control Word, Reference and Process Data are used with

All-in-One applications as follows.
