What causes KUKA Robot alarm KRC0143?

Robot number parameter in the KRC configuration file does not match the physical robot model or serial number. Corrupted or incorrect robot.ini or system configuration file entries. Firmware or software version mismatch between controller and robot mechanical unit. Hardware modifications or robot replacement without corresponding software configuration updates. EEPROM or parameter storage corruption in the robot controller or drive electronics.

How do I fix KUKA Robot alarm KRC0143?

1. Access the KRC controller's configuration menu and verify the robot number parameter matches the physical robot's model designation and serial number label 2. Check the robot.ini configuration file and system files for correct robot type entries; cross-reference against the robot's nameplate specifications 3. Power cycle the controller completely and perform a system initialization to refresh parameter validation 4. Verify firmware versions on the KRC controller and all connected robot axes match the expected versions for the installed robot model 5. If configuration is correct, backup current settings and reconfigure the robot number parameter using the KUKA teach pendant or engineering software, then save and reinitialize 6. If the alarm persists, contact KUKA service to verify hardware integrity or replace the controller backup battery to restore EEPROM if necessary

Alarm KRC0143

KUKA Robot KRC0143 - Check robot number

This alarm indicates that the robot number configured in the KRC controller does not match the actual hardware or system configuration. The controller is unable to verify the robot's identity during initialization or runtime parameter validation. This typically occurs when there is a mismatch between the software configuration and the physical robot installation.
