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 (output
frequency) of the motor using only digital signals. To enable the macro, set the value
of parameter 9902 APPLIC MACRO
For the parameter default values, see section
page 165. If you use other than the default connections presented below, see section
I/O terminals on page 49.

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