90
Assignment of motor – inverter incorrect
SEW Eurodrive · [PDF] Operating Instructions
What does 90 mean?
The assigned motor type does not correctly match the MOVIMOT inverter, for example, an MM03 inverter paired with a DT71D4 motor. This mismatch can lead to incorrect operational characteristics, insufficient or improper motor protection, and potentially premature component failure or reduced performance.
Common Causes
- Mismatched motor and inverter combination (e.g., MM03 – DT71D4).
- Incorrect configuration or parameter assignment for the connected motor.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the compatibility of the connected motor with the MOVIMOT frequency inverter model using the official product documentation or selection software.
- 2
Check the inverter and motor nameplates to confirm the correct combination as per SEW-EURODRIVE specifications.
- 3
Reset the fault by switching off the DC 24 V supply voltage to the inverter for at least 10 seconds.
