Motor potentiometer
The motor potentiometer is a counter whose value can be adjusted up and down
using two digital signals selected by parameters.
When enabled, the motor potentiometer assumes a set value. Depending on the
mode selected, the motor potentiometer value is either retained or reset over a power
cycle.
The change rate is defined as the time it would take for the value to change from the
minimum to the maximum, or vice versa. If the up and down signals are
simultaneously on, the motor potentiometer value does not change.
The output of the function is shown, and it can be directly set as the reference source
in the main selector parameters, or used as an input by other source selector
parameters.
The following example shows the behavior of the motor potentiometer value.
