Motor potentiometer macro

This macro provides a cost-effective interface for PLCs that vary the speed of the
drive 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

see section

Default I/O connections

1)
If DI3 and DI4 are both active or inactive, the
frequency reference is unchanged.
The existing frequency reference is stored
during stop and power down.
