Unknown or Incompatible Power Board

What does InF2 mean?

The drive has detected an unknown or incompatible power board. This means the control section cannot properly interface with the power section, leading to a complete failure to operate. This is a critical internal hardware fault.

• The installed power board is not recognized or is incompatible with the drive.
• Incorrect power board for the drive series installed.
• Damaged communication traces between the control and power board.
• Firmware mismatch between control and power board.
