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
to 4 (MOTOR POT).
For the parameter default values, see section
on page 142. If you use other than the default connections presented below, see
section

Default I/O connections

max. 500 ohm

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.
