F109

Mismatch C-P

Allen-Bradley · PowerFlex 520-series Adjustable Frequency AC Drive

What does F109 mean?

The control module has been mounted to a power module of a different drive type or series than it is designed for. This mismatch in hardware architecture prevents proper initialization and operation, as the control module's firmware cannot correctly interface with the power section.

Complete Troubleshooting Guide

  1. 1

    Set parameter P053 [Reset To Defalts] to '3' ('Power Reset') to force the control module to re-detect and re-configure itself specifically for the attached power module.
