22.71 Motor
potentiometer
function
Activates and selects the mode of the motor potentiometer.
See section DC voltage control (page 80).
Disabled
Disabled Motor potentiometer is disabled and its value set to 0. 0
Enabled (init at stop
/power-up)
When enabled, the motor potentiometer first adopts the value
defined by parameter 22.72 Motor potentiometer initial value.
The value can then be adjusted from the up and down
sources defined by parameters 22.73 Motor potentiometer up
source and 22.74 Motor potentiometer down source.
A stop or a power cycle will reset the motor potentiometer to
the initial value (22.72).
1
Enabled (resume
always)
As Enabled (init at stop /power-up), but the motor
potentiometer value is retained over a power cycle.
2
Enabled (init to
actual)
Whenever another reference source is selected, the value of
the motor potentiometer follows that reference. After the
source of reference returns to the motor potentiometer, its
value can again be changed by the up and down sources
(defined by 22.73 and 22.74).
3
22.72 Motor
potentiometer initial
value
Defines an initial value (starting point) for the motor
potentiometer. See the selections of parameter 22.71 Motor
potentiometer function.
0.00
-32768.00…
32767.00
Initial value for motor potentiometer. 1 = 1
22.73 Motor
potentiometer up
source
Selects the source of motor potentiometer up signal.
0 = No change
1 = Increase motor potentiometer value. (If both the up and
down sources are on, the potentiometer value will not
change.)
