Unit utilization

Hva betyr 44 ?

Immediate switch-off with inhibit because the unit utilization (Ixt value) has been exceeded. This indicates the inverter is being overloaded for an extended period, which can cause overheating and potential damage to the power stage if not addressed.

• The drive has exceeded its programmed utilization limits.
• Overload condition sustained for too long (check parameter P1-10).
• Duty cycle exceeds the design specifications for the drive.
• Incorrect motor data entered, leading to overestimation of load.

1. 1

   Decrease the power output from the unit by reducing the load on the motor.

2. 2

   Extend acceleration/deceleration ramps to reduce peak current loads during transient operations.

3. 3

   If reducing load or extending ramps is not feasible, consider using a larger inverter with a higher current rating.
