Encoder fault

Hva betyr 43 ?

A problem has been detected in the encoder signals. Subcodes pinpoint specific issues such as missing channel A or B signals, both channels missing, encoder reversed, missing encoder board, serial communication fault, channel A/B mismatch, resolver/motor pole pair mismatch, or missed start angle.

• Encoder signal is missing, incorrect, or noisy.
• Encoder wiring is disconnected or damaged.
• Encoder is faulty or has failed internally.
• Encoder resolution or type mismatch with drive configuration.
• High electrical noise interfering with encoder signals.

1. 1

   Check the physical connections of the encoder channel A and B signals to the frequency converter.

2. 2

   Check the physical connection and integrity of the encoder board within the drive.
