FIELD SENSE FAULT

¿Qué significa 925 ?

The field bridge rating is determined by a sense resistor on the Field Interface board, selected by SW1, which sets the motor field current feedback scaling for the A/D converter. If this resistance value is not recognized, a Field Sense Fault is declared, indicating a hardware fault on the Field Interface PCB, Drive Control PCB, or interconnecting cables and hardware. A DSD power down is required.

• The resistance value from the field sense resistor selected by SW1 on the Field Interface board is unrecognized.
• Hardware fault on the Field Interface PCB.
• Hardware fault on the Drive Control PCB.
• Defective interconnecting cables or hardware, such as J13 not being properly seated.

1. 1

   Check that connector J13 is properly seated on the Field Interface board.

2. 2

   Verify the integrity of the interconnecting cable for any defects.

3. 3

   Confirm that the correct field sense resistor is selected by SW1 on the Field Interface PCB.

4. 4

   If problems persist, replace the Field Interface PCB or the Drive Control PCB.

5. 5

   Perform a DSD power down after troubleshooting.
