Encoder Phase A/B Swapped

Hva betyr 7302 ?

The pulse encoder phasing is incorrect, specifically Phase A is connected to the terminal for Phase B and vice versa. This will result in incorrect speed or position feedback, potentially causing motor rotation direction issues or control instability.

• Incorrect wiring of encoder phase signals A and B.
• Encoder signals A and B are reversed in the control unit configuration (P3-01, P3-02).
• Faulty encoder sensor generating swapped phase signals.
• Improper installation or setup of the encoder feedback.
