Encoder 1 error: signal amplitude incorrect

What does F2031 mean?

The analog signal amplitude from encoder 1 is outside the expected range, indicating a problem with the encoder, its cabling, or the drive's input circuit. This affects position and velocity feedback accuracy.

• Faulty encoder hardware or aging components.
• Damaged or improperly shielded encoder cabling.
• Incorrect termination or impedance matching for the encoder signals.
• Damage to the drive's encoder input circuit.

Click steps to track your progress.

1. 1

   Inspect the cabling for encoder 1 for physical damage, proper shielding, and secure connections. Check for proper signal ground connections.

2. 2

   Verify the encoder's power supply voltage at the encoder terminals. Incorrect voltage can affect signal amplitude.

3. 3

   If possible, use an oscilloscope to measure the differential signal amplitude of the encoder at the drive's input. Compare with the encoder's specifications.

4. 4

   Check drive parameters related to encoder input configuration, such as termination settings. If the fault persists, the encoder or drive input may be defective.
