Option fault

What does 35 mean?

An alarm specific to an option card has been received, likely due to a power-up issue or a communication fault with the installed option card. This indicates the option card is not functioning correctly, compromising any features or connectivity it provides. This may require further diagnosis depending on the specific option.

• The option card (e.g., MCB101, MCA101) is not correctly or fully seated in its designated slot (e.g., Slot A) within the drive.
• Insufficient or unstable power supply to the option card due to a faulty backplane connection or power supply issue within the drive.
• Hardware failure of the option card itself (e.g., component damage, internal fault).
• Firmware incompatibility between the drive's main control board and the installed option card.
• Misconfiguration of parameters specifically related to the option card (e.g., P20-01, Analog Input Scale for I/O card).

Click steps to track your progress.

1. 1

   1. Power down the drive, remove the option card, and re-insert it firmly into its designated slot (e.g., Slot A) ensuring all connectors are fully seated.

2. 2

   2. Observe any status LEDs on the option card during power-up for specific error codes or patterns (e.g., flashing red LED indicating fault).

3. 3

   3. Verify that all parameters relevant to the installed option card (e.g., P20-xx for I/O functions, P8-xx for communication settings) are correctly configured according to the application.

4. 4

   4. Measure the supply voltage (e.g., 5VDC, 24VDC) to the option card's power pins (if accessible) to confirm it meets specifications.

5. 5

   5. If available, test the drive with a known good and compatible replacement option card to isolate whether the fault lies with the card or the drive's main unit.
