No Marker Pulse2

Was bedeutet 33 ?

This error occurs if the marker pulse from the Axis 2 encoder is not detected within one full rotation during the Axis 2 homing cycle, or if a continuous marker pulse signal is present. This points to a problem with the marker pulse feedback for Axis 2.

• Disconnected or faulty wiring for the marker pulse at CLM01.3-M connector X2, pins 3 and 4.
• Defective Axis 2 encoder, failing to generate a marker pulse or generating a continuous pulse.
• Incorrectly set homing parameters (e.g., Parameter 48 or 49) preventing proper marker pulse search for Axis 2.
• Noise or interference on the encoder feedback lines disrupting Axis 2 marker pulse detection.

1. 1

   Switch the marker pulse wires at CLM01.3-M connector X2, pins 3 and 4 (if incorrect polarity is suspected).

2. 2

   Verify that the Axis 2 encoder is correctly installed and free from physical damage.

3. 3

   Inspect the Axis 2 encoder cable for any signs of damage, shorts, or poor shielding.

4. 4

   Review Parameter 48 (Homing Setup A2) and Parameter 49 (Homing Offset A2) for Axis 2 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.
