A local emergency stop in a Kuka robot is a safety device that allows the operator to immediately halt the robot's operation in case of an emergency or hazardous situation.
The "Local Emergency Stop" (often referred to as "Local E-Stop") error in a KUKA robot controller indicates that an emergency stop condition has been triggered from a local source. This is typically an emergency stop button or switch located directly on or near the robot or its control panel. The purpose of a local emergency stop is to provide an immediate means of halting the robot’s operation in case of a safety issue or urgent situation.
Troubleshooting Steps:
-
Check the Emergency Stop Button:
- Inspect the local emergency stop button for any physical damage or obstruction. Ensure it is not stuck or pressed inadvertently.
- If the button is pressed, release it and reset the system according to the manufacturer’s instructions.
-
Verify Safety Circuit Integrity:
- Check the wiring and connections associated with the emergency stop system to ensure they are secure and intact.
- Look for any signs of damage, wear, or disconnection in the safety circuits.
-
Test the Emergency Stop System:
- Test the functionality of the emergency stop button by pressing and releasing it to confirm it operates correctly.
- If the button does not return to its normal position or continues to trigger the stop condition, consider replacing it.
-
Inspect Safety Devices:
- If there are external safety devices connected to the emergency stop system, such as safety gates or sensors, verify that they are functioning correctly and not falsely triggering the stop condition.
-
Review Safety Configuration:
- Check the safety settings and configurations in the robot controller’s software to ensure they are set up correctly.
- Verify that the safety parameters match the intended setup and operational requirements.
