KUKA Robot KRC0277 - REFPO DETERMINES AXIS <axis>

REFPO DETERMINES AXIS <axis>

This is an informational alarm indicating that the reference point (home position) calculation has been completed for the specified axis during the referencing process. This output message is generated after the REFPO (reference point) routine successfully determines the mechanical zero position for the axis, which is essential for establishing the coordinate system and enabling normal robot operation.

Common Causes

  • Normal completion of axis referencing procedure
  • Successful execution of reference point search routine
  • Axis encoder or position feedback initialization
  • Home position calibration completion
  • System startup or controller power-on sequence

Troubleshooting Steps

  1. 1Verify the alarm appears during normal robot startup or referencing sequence, as this is typically an informational message rather than an error condition
  2. 2Check that the axis identified in the alarm message is functioning correctly and responding to commands after the message appears
  3. 3Confirm that all axes complete their REFPO routine successfully by monitoring the complete startup sequence
  4. 4Review the robot's parameter settings and reference point offsets in the system configuration to ensure they are correct
  5. 5If axis motion is restricted or inaccurate after this alarm, initiate a manual axis referencing procedure using the teach pendant
  6. 6Contact KUKA support or consult the robot's technical documentation if referencing fails or the alarm prevents normal operation
