Activates and selects the mode of the motor
potentiometer.
See section Motor potentiometer (page
Motor potentiometer is disabled and its value set to 0.
When enabled, the motor potentiometer first adopts
the value defined by parameter
potentiometer initial value.
When the drive is running, the value can be adjusted
from the up and down sources defined by parameters
22.73 Motor potentiometer up source
potentiometer down source.
A stop or a power cycle will reset the motor
potentiometer to the initial value (22.72).
As Enabled (init at stop/power-up), but the motor
potentiometer value is retained over a stop or a power
cycle.
Defines an initial value (starting point) for the motor
potentiometer. See the selections of parameter
