MR12

Alarm Space 12 Violation

Kuka · KK53Y Servo Motor

What does MR12 mean?

The MR12 signal indicates a violation of monitoring space 12. A '0' state on this signal means that monitoring space 12 is currently being infringed upon. If monitoring space 12 is intentionally inactive, the system considers it violated by default, and the associated safe output MR12 will be in the '0' state.

Common Causes

  • Alarm condition triggered in Space 12 of the monitoring system.
  • Parameter P12 has exceeded its defined alarm threshold.
  • Sensor associated with Space 12 reporting an out-of-bounds value.
  • Configuration error in Space 12 alarm limits.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Identify the configured boundaries for monitoring space 12 in the robot's programming environment (e.g., using KUKA WorkVisual).

  2. 2

    Physically inspect the robot's current position and ensure no part of the manipulator, external axes, or tooling is entering or has entered the defined monitoring space 12.

  3. 3

    If monitoring space 12 is intended to be inactive, verify this configuration in WorkVisual and acknowledge that the MR12 signal will default to a '0' (violated) state.
