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.
