The motor encoder for the displayed axis is defective. This is a critical error as the encoder provides position and speed feedback essential for axis control.
Click steps to track your progress.
Power cycle the machine to reset the encoder and control system, clearing any transient communication issues.
Inspect the motor encoder and its cabling for any visible damage, contamination, or loose connections at both the encoder and control ends.
Verify the encoder's power supply voltage is present and stable, within the specified operating range.
If possible, perform basic continuity or resistance checks on the encoder's output lines (refer to the encoder's datasheet for expected values).
If the encoder is confirmed defective or suspicious after these checks, replacement with a compatible unit and proper parameter configuration will be necessary.
