44
Unit Utilization Exceeded
SEW Eurodrive · MOVIDRIVE compact System (MCF/MCV/MCS4_A)
What does 44 mean?
Immediate switch-off because the inverter's utilization (IxT value), representing its thermal load, has exceeded 125%. This means the inverter is operating beyond its continuous thermal capacity, risking overheating and damage.
Common Causes
- The cumulative usage or operating time of the unit has exceeded its design limit.
- High duty cycle or continuous operation impacting component lifespan.
- Parameter related to unit utilization has reached its threshold.
- Preventive maintenance reminder based on usage.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Decrease the power output or load demand on the inverter.
- 2
Extend acceleration and deceleration ramps to reduce peak current demands.
- 3
If reducing load or extending ramps is not feasible, consider installing a larger inverter appropriate for the application's demands.
