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. 1

    Decrease the power output or load demand on the inverter.

  2. 2

    Extend acceleration and deceleration ramps to reduce peak current demands.

  3. 3

    If reducing load or extending ramps is not feasible, consider installing a larger inverter appropriate for the application's demands.
