Motor Potentiometer Macro; Default I/O Connections - ABB ACS355 User Manual

Motor potentiometer macro

This macro provides a cost-effective interface for PLCs that vary the speed of the
motor using only digital signals. To enable the macro, set the value of parameter
APPLIC MACRO to 4
For the parameter default values, see section
page 176. If you use other than the default connections presented below, see section
I/O terminals on page 51.

If DI3 and DI4 are both active or inactive, the
speed reference is unchanged.
The existing speed reference is stored
during stop and power down.
