Motor Potentiometer Macro; Default I/O Connections - ABB ACS310 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 (MOTOR POT).
For the parameter default values, see section
page 151. If you use other than the default connections presented below, see section
on page 49.

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.
