Motor potentiometer
The motor potentiometer is, in effect, a counter whose value can be adjusted up
and down using two digital signals selected by parameters 22.73 and 22.74. Note
that these signals have no effect when the drive is stopped.
When enabled by 22.71, the motor potentiometer assumes the value set by 22.72.
Depending on the mode selected in 22.71, the motor potentiometer value is either
retained or reset over a stop or a power cycle.
The change rate is defined in 22.75 as the time it would take for the value to change
from the minimum (22.76) to the maximum (22.77) 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 by 22.80, which can directly be set as the
source of any selector parameter such as 22.11.
The following example shows the behavior of the motor potentiometer value.
