This error typically indicates a communication issue between your device and the power management service, which is responsible for managing power consumption and system resources.

The "No communication to Power Management Service" error on a KUKA robot indicates that the robot's controller is unable to communicate with the Power Management Service (PMS). This service is crucial for managing power distribution and monitoring power-related functions within the robot's control system.

Steps to Troubleshoot and Resolve:

1. Restart the Controller:

   • Perform a controlled restart of the robot's controller. This can sometimes resolve temporary software glitches that might be affecting the Power Management Service.
   • After restarting, check if the communication is restored.

2. Check the Power Supply:

   • Ensure that the power supply to the controller is stable and within the required specifications.
   • Inspect the power supply unit (PSU) for any signs of malfunction or failure.

3. Inspect Cables and Connections:

   • Check all cables and connections related to the controller's power management system for any signs of damage, wear, or looseness.
   • Ensure that all connections are secure and functioning properly.

4. Verify that the Service is Running:

   • Use the KUKA SmartPad or remote desktop access to check whether the Power Management Service is running on the controller.
   • If the service is not running, attempt to start it manually. If it fails to start, there may be an underlying software or hardware issue.

5. Update Software and Firmware:

   • Ensure that the controller’s software and firmware are up to date. If not, update to the latest version provided by KUKA.
   • Firmware updates may include fixes for bugs or compatibility issues that could be causing the communication problem.
