KUKA Robot KRC0993 - COMBINED ANALOG SIGNALS INADMISSIBLE 2330

COMBINED ANALOG SIGNALS INADMISSIBLE 2330

This alarm indicates that combined analog input signals have exceeded permissible limits or contain inadmissible values on the robot controller. The analog signal combination from multiple input channels is invalid or outside the acceptable operating range for the system.

Common Causes

  • Multiple analog input signals simultaneously out of specification or corrupted
  • Faulty analog input module or signal conditioning circuitry
  • Incorrect wiring or loose connections on analog input terminals
  • Analog signals interfering with each other or cross-talk between channels
  • Controller firmware issue or corrupted analog signal calibration data

Troubleshooting Steps

  1. 1Verify all analog input cable connections are secure and properly terminated
  2. 2Measure individual analog input voltages/currents with a multimeter to confirm they are within specification
  3. 3Check for proper shielding and grounding of analog input cables to eliminate noise interference
  4. 4Review the analog input module configuration in the controller to ensure correct channel mapping
  5. 5Perform analog input calibration or reset to factory defaults if available
  6. 6If alarm persists, replace the analog input module or contact KUKA service for controller diagnostics
