Fieldbus control with embedded fieldbus 323
Reference handling
The control of rotation direction is configured for each control location (EXT1 and
EXT2) using the parameters in group
. Fieldbus references are
bipolar, ie, they can be negative or positive. The following diagrams illustrate how
group 10 parameters and the sign of the fieldbus reference interact to produce the
reference REF1/REF2.
Direction determined by
the sign of COMM
Direction determined by digital
command, eg, digital input,
control panel
