KUKA Robot KRC0814 - “ENDSWITCH” MISSING 2150

“ENDSWITCH” MISSING 2150

The robot's end-of-travel limit switch (mechanical or software end switch) is not functioning or cannot be detected on axis 2150. This safety mechanism prevents the robot from exceeding its physical joint limits, and its absence or failure poses a critical safety risk.

Common Causes

  • End switch sensor disconnected or loose wiring on axis 2150
  • Defective or failed end switch hardware component
  • End switch signal not reaching the robot controller due to cable damage
  • End switch configuration missing or incorrect in the robot's system data
  • Safety relay or input module failure preventing signal detection

Troubleshooting Steps

  1. 1Verify the end switch physical connection and wiring integrity on axis 2150
  2. 2Use a multimeter to test continuity and proper switch operation at the hardware level
  3. 3Check system data configuration files to confirm end switch is properly defined for axis 2150
  4. 4Inspect cable routing for damage, crimping, or disconnection between switch and controller
  5. 5Perform a safety circuit test through the teach pendant or diagnostics menu to verify signal pathway
  6. 6If all checks pass, replace the end switch sensor and perform a system reset before resuming operation
