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.
