About Zero Clamp PIDF Control Mode
Note:
The Zero Clamp PIDF mode is intended only for electromechanical (non-hydraulic) test systems.
The Zero Clamp PIDF control mode is typically used in systems that use rotary actuators in which back spin
and creep at zero cannot be tolerated, such as dynamometer systems.
This control mode is similar to the Basic PIDF control mode, with the following special features:
•
It includes a control that automatically clears the integrator when the actual command and feedback
amplitudes are within tolerance. This prevents back spin when zero is achieved.
•
It includes a control that automatically clamps the valve driver output when the actual command and
feedback amplitudes are within tolerance. This prevents creep at zero, as well as preventing back spin.
How to Create a Zero Clamp PIDF Control Mode
Note:
The Zero Clamp PIDF mode is intended only for electromechanical (non-hydraulic) test systems.
Note:
If you intend to use station input resources to create this control mode, you must create them before
proceeding.
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 a resource for the active feedback input (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 Zero-Clamp PIDF for Type.
5. Enter the desired display and internal names for the Active Fdbk, then select the desired Dimension and
Display Units.
6. Optional—allocate a resource for Stabilization (and if available, Stabilization 2).
