Unit utilization

What does F44 mean?

The inverter's internal utilization (I × t value) has exceeded its safe operating limits, indicating a prolonged or excessive overload condition. This fault causes an immediate switch-off with inhibit to protect the inverter from damage.

• Motor or load demands continuously exceed the inverter's rated current capacity
• Ramp times are too short, leading to high peak currents during acceleration/deceleration
• The connected motor/load requires more power than the inverter can safely deliver

Click steps to track your progress.

1. 1

   Reduce the mechanical load on the motor to decrease power output requirements.

2. 2

   Increase the acceleration and deceleration ramp times to lower peak current demands.

3. 3

   If current inverter capacity is insufficient, consider using a larger MOVITRAC® B inverter.
