KUKA Robot KRC0109 - PLEASE SWITCH OFF THE CABINET

PLEASE SWITCH OFF THE CABINET

The servo file configuration has been successfully loaded into the KRC4 memory, but the drive servo parameters will not become active until the cabinet performs a complete power-on restart. This is a normal operational message that requires system reboot to apply changes.

Common Causes

  • New servo parameters were loaded via WorkVisual or KUKA smartPAD without triggering an automatic reboot
  • Drive servo configuration file was modified to adapt to different axis hardware or motor specifications
  • Firmware update was applied that includes modified servo tuning parameters
  • Motor encoder type or gear ratio was changed in the servo configuration
  • Servo gain values were adjusted to optimize robot performance for specific applications

Troubleshooting Steps

  1. 1Acknowledge the alarm message on the KUKA smartPAD display to clear the notification
  2. 2Verify that the new servo configuration is correct by reviewing the loaded servo file parameters
  3. 3Power down the robot cabinet completely using the main disconnect switch
  4. 4Wait 30 seconds to ensure all capacitors are fully discharged, then power the cabinet back on
  5. 5Monitor the boot sequence and verify the message DRIVES READY appears after initialization completes
  6. 6Test robot motion in manual mode on the KUKA smartPAD to confirm servo parameters are functioning correctly
