Fieldbus control with embedded fieldbus
254
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, i.e. 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.
Actual value scaling
The scaling of the integers sent to the master as Actual Values depend on the
selected function. See chapter
.
Direction determined by the sign of
COMM
Direction determined by digital command,
e.g. digital input, control panel
