Initial Position Detection Fault

¿Qué significa E-39 ?

This fault is detected at startup if the measured current during initial position detection is either too small or too large, indicating a mismatch with the motor's inductance or an output phase loss.

• Measured current at initial position detection is too small or too large.
• Motor inductance is not correctly identified (too small or too large).
• Output phase loss during initial detection.

1. 1

   Check all motor phase connections (U, V, W terminals) for continuity and tightness.

2. 2

   Verify the maximum current allowed by the drive configuration settings.

3. 3

   Assess the motor's inductance to ensure it is within expected limits for the application.
