Application macros
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 9902
APPLIC MACRO to 4 (MOTOR POT).
For the parameter default values, see section Default parameter values with different
macros on page 79. If you use other than the default connections presented below,
see section I/O terminals on page 44.

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.
