42

Lag error

SEW Eurodrive · MOVIDRIVE compact System

What does 42 mean?

The actual position or speed deviates significantly from the commanded value, potentially due to incorrect encoder connection, short acceleration ramps, a small P-component in the positioning controller, incorrect speed controller parameters, or an insufficient lag fault tolerance. This causes an immediate disconnection to prevent further uncontrolled movement.

Complete Troubleshooting Guide

  1. 1

    Check the encoder connection thoroughly for any wiring errors, shorts, or loose connections.

  2. 2

    Extend acceleration/deceleration ramps to allow the motor to follow commands more smoothly and reduce lag.

  3. 3

    Increase the P-component value of the positioning controller to improve responsiveness and reduce deviation.

  4. 4

    Reset or re-tune speed controller parameters if they are incorrectly set or not optimized for the load.

  5. 5

    Increase the lag fault tolerance value if minor deviations are acceptable for the application and do not pose a risk.
