LCD Panel for FCU6-DUN22 Mitsubishi system

Overview

FCU6-DUN22 is a dedicated fan drive unit belonging to Mitsubishi FCU6 numerical control series, professionally designed to match spindle drive modules of vertical machining centers, CNC lathes and multi-axis milling machines. As a supporting cooling control component, this FCU6-DUN22 independently regulates the cooling fans built inside spindle power drive units, precisely adjusting fan rotating speed according to real-time spindle operating load and internal module temperature.

Different from general-purpose fan control boards, FCU6-DUN22 adopts Mitsubishi original matching circuit architecture, which realizes real-time temperature signal interaction with FCU6 spindle drivers without extra signal conversion adapters. It supports automatic speed adjustment, over-temperature fan full-speed forced cooling and stall fault self-diagnosis functions, effectively preventing spindle drive overheating damage during long-cycle heavy cutting operations. Standard pin terminal layout and fixed rack mounting size fully fit original CNC electrical cabinet internal structure, realizing plug-and-play replacement for aging drive fan control assemblies. With industrial-grade anti-vibration and dustproof circuit protection, FCU6-DUN22 becomes a necessary supporting spare part for new CNC machine assembly and old Mitsubishi FCU6 series spindle drive system maintenance renovation projects.
