Chapter: Encoder Problems¶

Overview¶

Encoder faults, noise, slip, and replacement. Encoders are critical position feedback devices on each axis. Encoder issues directly cause positional errors, axis trips, and repeatability failures.

Scope¶

Encoder fault messages
Encoder noise and signal quality
Encoder slip
Encoder replacement procedure
Re-zeroing after encoder replacement
Encoder cable faults
EtherCAT encoder interface issues
