Motor parameter identification fault

Hva betyr 65305 ?

An error occurred during the automatic identification process of the connected motor. This indicates a mismatch between the drive's expectation and the motor's actual electrical characteristics or a problem with motor wiring. This could lead to incorrect motor operation or damage.

• Motor not correctly wired to the drive (U, V, W terminals), or a phase is open-circuited during the identification process.
• Incorrect motor nameplate data (e.g., P300.00-P304.00) entered into the drive's parameters before starting identification.
• Mechanical load connected to the motor shaft during identification, preventing accurate measurement of motor inductance and resistance.
• Faulty motor windings or internal short circuits, causing anomalous electrical characteristics during the test.
• Drive output stage fault or current measurement circuit error, leading to inaccurate readings during the identification routine.

1. 1

   Verify correct wiring of motor phases (U, V, W) to the drive output terminals. Ensure all connections are secure.

2. 2

   Disconnect the mechanical load from the motor shaft before initiating the automatic motor identification process.

3. 3

   Double-check and re-enter all motor nameplate data (P300.00 for rated power, P301.00 for rated voltage, P302.00 for rated current, P304.00 for rated speed).

4. 4

   Measure motor winding resistance between phases (U-V, V-W, W-U) and compare to expected values. Check for open circuits or shorts.

5. 5

   If the issue persists, attempt a manual motor parameter entry if possible, or contact technical support for drive diagnostics.
