Frequenz CDM6- CU

The Frequenz CDM6‑CU is a modern replacement control unit designed specifically to swap out the old Crawford 430 controller on CDM6 motors, offering a plug‑and‑play upgrade with clearer diagnostics and easier setup. It’s essentially a reprogrammed Frequenz 400 V controller tailored for CDM6 drives, complete with an adapter board for the mechanical limit switches.
