Coding of process data

The same process data information is used for controlling and selecting setpoints for all
fieldbus systems. The process data are coded using the uniform MOVILINK

®

profile for

SEW drive inverters. In the case of MOVIMOT

®

, it is always possible to differentiate be-

tween the following variants:

Two process data words (2 PD)

Three process data words (3 PD)

Two process data
words

In order to control MOVIMOT

®

using two process data words, the process output data

"Control word 1" and "Speed [%]" are send to the master programmable controller for
MOVIMOT

®

; the process input data "Status word 1" and "Output current" are sent from

MOVIMOT

®

to the programmable controller.

Three process
data words

When control takes place with three process data words, 'Ramp' is sent as additional
process output data word; "Status word 2" is sent as third process input data word.
