SEW Eurodrive · MOVIDRIVE MDX60B/61B Variable Speed Drive

What does F109-42 mean?

The current acceleration has exceeded the configured maximum acceleration limit. This indicates a discrepancy between actual motor dynamics and the set parameters, potentially due to incorrect configuration or mechanical issues.

Common Causes

  • Measured acceleration value exceeds plausible limits.
  • Encoder velocity or position data indicates unrealistic acceleration.
  • Incorrect configuration of acceleration monitoring parameters.
  • Sensor malfunction causing erratic acceleration readings.
