Alarm KRC0097

KUKA Robot KRC0097 - DRIVES PARAMETER DATA ** INVALID

This alarm indicates that the drive parameter data stored in the robot controller's memory has become corrupted or invalid, preventing proper motor control initialization. The KRC controller cannot establish valid communication or configuration with the drive modules, which blocks the robot from entering Ready state and executing any motion commands.

KUKA Robot KRC0097 - DRIVES PARAMETER DATA ** INVALID

DRIVES PARAMETER DATA ** INVALID

This alarm indicates that the drive parameter data stored in the robot controller's memory has become corrupted or invalid, preventing proper motor control initialization. The KRC controller cannot establish valid communication or configuration with the drive modules, which blocks the robot from entering Ready state and executing any motion commands.

Common Causes

  • Corrupted drive parameter file in the controller's flash memory or configuration storage
  • Incomplete or interrupted parameter download during system initialization or firmware update
  • Hardware failure in the drive electronics or communication interface between controller and drive modules
  • Incompatible or mismatched drive firmware version relative to the KRC controller software version
  • Power loss or unexpected shutdown during drive parameter initialization or calibration sequence

Troubleshooting Steps

  1. 1Power cycle the robot controller completely by switching off the main power supply for at least 30 seconds, then power on and observe if the alarm clears during initialization
  2. 2Access the KRC controller's system diagnostics menu to verify drive module detection and check the status of each axis drive in the Hardware Configuration
  3. 3Verify that all drive parameter files are properly loaded by navigating to the parameter management section and comparing current parameters against the documented baseline or backup configuration
  4. 4Re-download and reload the drive parameters from the KUKA engineering software (KUKA.Sim or KRC engineering interface) to restore valid configuration data to the controller
  5. 5Check all electrical connections between the controller and drive modules, including terminal blocks and ribbon cables, ensuring no loose connections or visible damage
  6. 6If the alarm persists after parameter reload, contact KUKA support or perform a system recovery restore from a known-good backup configuration, as this may indicate hardware-level drive module failure requiring replacement
