No Marker Pulse!

What does 09 mean?

This error occurs if the marker pulse from the Axis 1 encoder is not detected within one full rotation during the homing cycle, or if a continuous marker pulse signal is present. This indicates a problem with the marker pulse feedback for Axis 1.

• Disconnected or faulty wiring for the marker pulse at CLM01.3-M connector X1, pins 3 and 4.
• Defective Axis 1 encoder, failing to generate a marker pulse or generating a continuous pulse.
• Incorrectly set homing parameters (e.g., Parameter 08 or 09) preventing proper marker pulse search.
• Noise or interference on the encoder feedback lines disrupting marker pulse detection.

Click steps to track your progress.

1. 1

   Check the wiring of the Marker Pulse wires at CLM01.3-M connector X1, pins 3 and 4 for secure connections and continuity.

2. 2

   Verify that the Axis 1 encoder is correctly installed and free from physical damage.

3. 3

   Inspect the Axis 1 encoder cable for any signs of damage, shorts, or poor shielding.

4. 4

   Review Parameter 08 (Homing Setup) and Parameter 09 (Homing Offset) for Axis 1 to ensure proper homing configuration.

5. 5

   If possible, use an oscilloscope to check for the presence and quality of the marker pulse signal directly at the encoder and at the CLM01.3-M input.
