Adjustable current limitation exceeded
SEW Eurodrive · [PDF] Operating Instructions
What does 44 mean?
The drive has operated at its current limit for longer than 500 ms while the 'Adjustable current limitation' (Additional function 2) is active. This function monitors current above 15 Hz and triggers a fault if the set maximum current (Imax [%] of IN) is continuously exceeded. This indicates the motor is drawing excessive current due to load or an inappropriately set current limit, posing a risk of motor and inverter damage.
Common Causes
- Drive operating at the current limit for longer than 500 ms.
- Excessive mechanical load on the motor exceeding the set current limitation.
- Incorrect setting of switch f2 for the current limitation percentage (Imax [%] of IN).
Repair Steps & Checklist
Click steps to track your progress.
- 1
Reduce the mechanical load on the drive system.
- 2
Check the setting of switch f2 (S2 for standard, S4 for AS-i) for the current limitation percentage (Imax [%] of IN) and adjust if necessary.
- 3
Verify that the application does not require continuous operation above 15 Hz at the current limit.
- 4
Increase the current limit setting via switch f2 if the load is within the motor's capabilities and the application demands it.
