MR2

Alarm Space 2 Violation

Kuka · KK53Y Servo Motor

What does MR2 mean?

The MR2 signal indicates a violation of monitoring space 2. A '0' state on this signal means that monitoring space 2 is currently being infringed upon. If monitoring space 2 is intentionally inactive, the system considers it violated by default, and the associated safe output MR2 will be in the '0' state.

Common Causes

  • Alarm condition triggered in Space 2 of the monitoring system.
  • Parameter P2 has exceeded its defined alarm threshold.
  • Sensor associated with Space 2 reporting an out-of-bounds value.
  • Configuration error in Space 2 alarm limits.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Identify the configured boundaries for monitoring space 2 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 2.

  3. 3

    If monitoring space 2 is intended to be inactive, verify this configuration in WorkVisual and acknowledge that the MR2 signal will default to a '0' (violated) state.
