Description Callout
Control Feedback (Force) 8
This control mode requires two feedback signals:
• Control feedback for the primary loop, which is provided when you select a Base Control Mode.
• Control feedback for the secondary loop, which is provided when you select a resource for the Cascaded
PIDF control mode (Active fdbk).
You can select a resource for the control feedback of the secondary loop from:
• The Hardware Input Resources list, or
• The Station Input Resources list associated with the selected channel or Auxiliary Inputs. (You cannot
select this feedback from station resources associated with other channels.)
How to Create a Cascaded PIDF Control Mode
Before you can create a Cascaded PIDF control mode, you must create a base control mode (primary control
loop).
1. In the Station Builder navigation pane, select the channel for which you wish to create this mode.
2. Click the Control Modes tab, and then select an input resource for the secondary control loop (Active fdbk)
by performing one of the following:
• Click the Station tab of the Input Resources list, select a station input (from the current channel or
Auxiliary Inputs), and click “+”, or
• Click the Hardware tab of the Input Resources list, select a hardware resource input for the control
mode, and click “+”.
Note:
Keep your resource names short because long names may not be visible in all windows.
3. Enter the desired display and internal name for the control mode.
4. Select Cascaded PIDF for Type.
5. Select the desired Cascaded Type.
6. Select the desired Base control mode.
7. Enter the desired display and internal names for the Active fdbk input, and then select the desired Dimension
and Display Units. This input pertains to the Cascaded PIDF control mode’s secondary control loop.
8. Optional—allocate a resource for Stabilization (and if available, Stabilization 2).
