E3107

Safety related reference missing

Indramat · IndraDrive MPx02

What does E3107 mean?

The IndraDrive MPx02's integrated safety technology is missing a required safety-related reference. This reference could be a specific position, velocity, or direction, which is crucial for safety functions like Safe Operating Stop or Safe Position monitoring. Without it, the safety system cannot guarantee safe operation.

Common Causes

  • The axis has not been safely homed or a safety-related reference point has not been established.
  • A critical encoder or sensor providing safety-related feedback is not active, has failed, or is incorrectly configured.
  • Incorrect parameterization of safety functions that require a validated reference position.
  • Loss of absolute position information for safety-related monitoring functions.
  • An invalid or unstable signal from a safety-related feedback device.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Ensure that the axis has undergone a successful safety-related homing procedure or that its absolute position reference is established and validated.

  2. 2

    Verify the functionality and wiring of any encoders or sensors designated for safety-related feedback to the IndraDrive MPx02.

  3. 3

    Check the safety configuration parameters to ensure that all required safety references are correctly defined and enabled.

  4. 4

    If using an absolute encoder for safety-related position monitoring, confirm its integrity and that its absolute position data is valid and retained.

  5. 5

    If the issue persists, review the machine's safety concept and the specific requirements for safety-related referencing, then contact Indramat safety service.
