Alarm KRC0360

KUKA Robot KRC0360 - ACKN. ERROR SYNC. INPUT DRIVE <axis>

This alarm indicates an acknowledgment error in the synchronous input drive communication for the specified axis. The KRC controller failed to receive proper acknowledgment from the drive when sending a synchronous input command, resulting in a communication or synchronization failure between the controller and the axis drive module.

KUKA Robot KRC0360 - ACKN. ERROR SYNC. INPUT DRIVE <axis>

ACKN. ERROR SYNC. INPUT DRIVE <axis>

This alarm indicates an acknowledgment error in the synchronous input drive communication for the specified axis. The KRC controller failed to receive proper acknowledgment from the drive when sending a synchronous input command, resulting in a communication or synchronization failure between the controller and the axis drive module.

Common Causes

  • Defective or loose encoder cable connection on the axis drive
  • Corrupted or outdated axis drive firmware version incompatible with KRC controller
  • Failed axis drive module requiring replacement
  • Electrical noise or EMI interference on the drive communication lines
  • Synchronization timing parameter misconfiguration in the axis configuration file

Troubleshooting Steps

  1. 1Power cycle the robot controller and verify the alarm persists after restart
  2. 2Check all encoder and drive communication cables for the affected axis for physical damage, loose connectors, or improper seating
  3. 3Verify the axis drive firmware version matches the KRC controller software version and update if necessary
  4. 4Inspect the axis drive module for visible damage, burnt components, or LED fault indicators
  5. 5Review the axis synchronization parameters in the configuration files and compare with factory specifications using KUKA.Diagnostics
  6. 6If the alarm persists, replace the axis drive module and perform axis calibration and re-teach if required
