Enc. 1: enc. signals incorr. (can be cleared in ph. 2)

What does F8022 mean?

Encoder 1, which is typically the primary motor feedback encoder, is providing incorrect or invalid signals. This could mean signal loss, noise, inverted signals, or a general malfunction preventing accurate position or velocity feedback to the IndraDrive.

• Loose, damaged, or incorrectly wired encoder cable.
• Faulty encoder unit.
• Electromagnetic interference (EMI) affecting encoder signals.
• Incorrect encoder configuration parameters (e.g., pole count, resolution).
• Defective encoder interface on the IndraDrive.

Click steps to track your progress.

1. 1

   Check the encoder cable for secure connections at both the drive and encoder ends, and inspect for physical damage.

2. 2

   Verify proper shielding and grounding of the encoder cable to prevent EMI.

3. 3

   Review IndraDrive parameters related to Encoder 1 configuration (e.g., S-0-0020 Encoder 1 Type, S-0-0021 Encoder 1 Resolution) and ensure they match the encoder specifications.

4. 4

   Test the encoder signals using an oscilloscope or specialized diagnostic tools, if available, to verify signal integrity.

5. 5

   If cable and parameters are correct, consider replacing the encoder, or if the fault persists, the drive's control section.
