Encoder Quadrature Error

¿Qué significa 90 ?

Both encoder channels (A and B) changed state within a single clock cycle. This suggests an issue with the encoder signal quality, possibly due to electrical noise or a damaged encoder, causing incorrect speed or position feedback.

• Encoder signals A and B are reversed or swapped.
• Encoder pulses are inconsistent or noisy.
• Incorrect encoder resolution set in drive parameters (e.g., P4-01).
• Faulty encoder or internal logic issue.

1. 1

   Check for externally induced noise on encoder cabling (e.g., proximity to power cables, proper shielding and grounding).

2. 2

   Replace the encoder unit.
