1.
Review Analog Input Mode settings in the I/O Configuration menu.
Select the analog voltage settings that map to the voltage of the actuator
you are using. In this case the Analog Input 1 maps to the 0 - 5 V DC
potentiometer.
2.
Set Selected Speed to Variable by completing the following:
a.
In Physical Input Mapping
Speed Select A, select Override and
select On.
b.
At Speed Select B, select Override and select On.
3. The
Quick Access view on the far right should now show Selected Speed
Mode: Variable. Recheck Input Mapping for the potentiometer and
related wiring if Selected Speed Mode is not Variable.
4. If using resistive input, set the potentiometer to the full clockwise
position.
5.
Set Variable Position Input Minimum and Input Maximum by either
manually adding settings or use the automatic calibration buttons.
a.
To set calibration automatically:
• Turn potentiometer fully CCW and click Calibrate Minimum.
• Turn potentiometer fully CW and click Calibrate Maximum.
b.
To set each manually:
• Set Input Minimum to between 0 to 75 %
• Set Input Maximum to at least 25 % greater than the Minimum
value. Values entered which are not 25 % different are
automatically reset to the closest accepted value by the GAConfig
Tool.
Variable Position Input Position shows the potentiometer value
when a potentiometer is used.
noTe
single remote speed adjustment potentiometer
to adjust the engine speed continuously over a specific speed range. Other
variable speed input devices include other controllers as well as J1939 data. Potentiometer wiring is shown in the
manual and in the previous section
Use the Tuning menu to adjust gain and to set each endpoint of
the speed range to add additional stability.
Gain (P), Stability (I), Deadtime (D), and Lead Circuit are shared
across the entire speed range. For each fixed speed create sepa
-
rate gain settings to create shared stability.
To maintain engine stability at the minimum speed setting, add a
small amount of droop, available in the Advanced Configuration
menu. At the maximum speed setting the governor performance
will be near isochronous, regardless of the droop adjustment
setting.
