A/D Conversion Error

¿Qué significa CPF02 ?

An error in the Analog-to-Digital (A/D) conversion circuit, which is responsible for converting analog input signals (e.g., speed reference, feedback) into digital values for the drive's control system. This impacts the accuracy or availability of analog inputs, potentially leading to incorrect operation.

• Faulty A/D converter chip on the control board due to component failure
• Excessive noise or interference on analog input lines leading to corrupted readings
• Damaged analog input circuitry on the drive's control board.

1. 1

   Check for external noise sources near analog input wiring and ensure proper shielding and grounding.

2. 2

   Verify stability of the analog input signal source (e.g., 0-10VDC or 4-20mA) with a multimeter.

3. 3

   Cycle power to the drive to reset the control circuit and reinitialize the A/D converter.
