Current Detection Error

What does E10 mean?

This fault indicates a malfunction within the inverter's internal current detection system, which is crucial for accurate motor control and protection. When this error occurs, the inverter immediately shuts off its output to prevent uncontrolled operation or damage.

• Internal current sensor (Hall effect sensor or shunt) failure or drift, providing incorrect current feedback.
• Noise or interference on the current sensor's signal lines, leading to erratic readings.
• Malfunction of the analog-to-digital converter (ADC) responsible for processing current sensor signals.
• Severe overload or short circuit condition that may have damaged the current sensing circuitry.
• Loose internal ribbon cable connections within the inverter's control board affecting sensor data integrity.

Click steps to track your progress.

1. 1

   Cycle the inverter's main power supply off for 5 minutes, then back on to attempt a reset of internal diagnostics.

2. 2

   Perform a no-load run test with the motor disconnected from the output terminals U, V, W to check current sensor readings (d0-03) at zero output.

3. 3

   Inspect internal control boards for any visible damage, burnt components, or loose ribbon cable connections.

4. 4

   Verify that all motor identification parameters (e.g., P1-02, P1-03, P1-04) are correctly set, as inaccurate settings can sometimes confuse current detection algorithms.

5. 5

   If the fault persists after basic troubleshooting, the inverter's main control board or power board may require replacement.
