ABB ACS310 User Manual

Fieldbus control with the embedded fieldbus 297
 Reference handling
The control of rotation direction is configured for each control location (EXT1 and
EXT2) using the parameters in group 10 START/STOP/DIR. 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.
 Actual value scaling
The scaling of the integers sent to the master as Actual values depends on the
selected function. See chapter Actual signals and parameters on page 163.
Direction determined by
