Current Measurement Circuit Error

Hva betyr InF9 ?

A detected error in the internal current measurement circuit. This is critical as the drive relies on accurate current feedback for motor control and protection. Inaccurate measurements can lead to incorrect torque, motor damage, or unstable operation.

• The internal current measurement circuit is faulty or reporting abnormal values.
• Defective current sensing transducers (e.g., Hall effect sensors).
• Calibration error in the current measurement circuitry.
• Short circuit or open circuit in the current sense feedback loop.

1. 1

   Power cycle the drive.

2. 2

   Check for any signs of physical damage to the drive's power board or current sensors.

3. 3

   Perform a motor auto-tuning procedure to recalibrate current sensors if possible and supported.

4. 4

   If the fault persists, it likely indicates a failure of the internal current measurement hardware, requiring repair or replacement.
