Internal Fault: Option software in slot B not supported

Danfoss · VLT HVAC Drive FC 102

Hva betyr 38.1316 ?

The software on the option card installed in slot B is not recognized or supported by the frequency converter's firmware. This indicates a fundamental incompatibility, preventing the option card from integrating correctly with the drive's control system.

Vanlige årsaker

  • Installation of an option card in slot B with unsupported or incompatible software (e.g., beta firmware, custom modification).
  • The drive's main firmware version is too old to recognize or interface with the software on the installed option card.
  • Corruption of the option card's firmware, rendering it unreadable or unrecognizable by the main drive.
  • Attempting to use an option card from a different product series or manufacturer that is physically installed but logically incompatible.
