Hand Feedback Value Health Bad

What does HandFBFaulted (Status1.3) mean?

This fault indicates that the Hand Feedback (Tieback) value health is bad. This occurs if the Hand FB value quality is bad, the value is invalid, or there's a communication fault with the input. In the PPID instruction, Sts_HandFdbkBad is also set if Inp_HandFdbk value is Infinite (Inf), Negative Infinite (-Inf), or Not-a-Number (NaN).

• Hand Feedback (Tieback) value quality is bad or unreliable
• Invalid Hand Feedback value (e.g., Inf, -Inf, or NaN for PPID)
• Communication fault with the Hand Feedback input module or source
• Inp_HandFdbkBad input (for PPID) is asserted

Click steps to track your progress.

1. 1

   Verify the Hand Feedback input signal at its source terminals using a multimeter or process calibrator

2. 2

   Check the communication status of the Hand Feedback input module in the I/O tree

3. 3

   Confirm that the Hand Feedback device is providing a valid, numerical, in-range signal

4. 4

   Review the logic driving Inp_HandFdbkBad (for PPID) to ensure it is not erroneously asserted
