Incompat MCB- PB

Allen-Bradley · PowerFlex 750 AC Drive

What does 106 mean?

The main control board (MCB) did not recognize the power structure (PB), indicating a firmware or hardware incompatibility, or a communication issue between the two boards. This prevents proper drive initialization and operation. The drive will not be able to function until the firmware revisions are harmonized.

Complete Troubleshooting Guide

  1. 1

    Flash the drive with a newer Application revision to ensure compatibility between the main control board and power structure.
