Calibration error

What does Er3 mean?

This error indicates that the analog input bias and gain calibration values (specifically C3, C4, C6, and C7) have been set too close to each other. This can lead to inaccurate analog signal processing and incorrect inverter behavior.

• Calibration data corrupted or lost.
• Calibration routine interrupted by power loss or command error.
• Sensor failure preventing successful calibration (e.g., P2-10 value out of range).
• Incorrect calibration procedure followed.

   Check and adjust the settings of calibration parameters C3, C4, C6, and C7 to ensure they are appropriately separated and within valid ranges.
