System compatibility

JANCD-CG22 belongs to Yaskawa Yasnac MX3 CNC controller family,matched with Yasnac MX3 vintage CNC systems. Widely used in old CNC lathes,milling machines and machining centers. This is a discontinued legacy graphic display board for old machine tool maintenance spare replacement.

Function

JANCD-CG22 serves as high precision CNC graphic control board. It receives axis position,NC program and alarm data from CNC main CPU board,converts digital data into CRT video signal and outputs to display monitor. It scans and collects key input signals from machine operation panel and transmits key commands to mainboard. Built-in opto-isolation and surge protection circuit to filter field interference. It is the interface board connecting CNC controller,CRT display and operator panel.

Installation

Mount JANCD-CG22 inside CNC controller cabinet. Complete backplane bus and display/panel wiring according to wiring drawing. Backup CNC parameters before replacement,verify CRT display and keypad input function after power-up.

Interface

‑System backplane bus multi-pin connector

‑CRT video signal port

‑Operator panel signal terminal

‑Onboard graphic processing and signal protection circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Stable video signal transmission,strong anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded.

Feature

JANCD-CG22 is obsolete Yaskawa Yasnac series spare part. Typical failures include screen flickering,blank display,panel key no response,intermittent graphic distortion. Check board integrity and connector pins before replacement. This board must match corresponding Yasnac MX3 CNC controller,direct substitution without display and panel function test is not recommended.

Diagnostic

When CRT no display,screen distortion or operation panel key failure occurs,the board triggers corresponding alarm codes and sends fault signal to CNC main controller.

Built‑in function

Graphic display data processing,operation panel key signal collection,video signal conversion,panel data communication,display channel fault monitoring,used as Yasnac CNC graphic control board spare replacement.

Product Brief

JANCD-CG22 is Yaskawa Yasnac MX3 CNC series graphic control board for vintage CNC machine tools and precision automation equipment. Confirm CNC controller model matching before ordering. ESD protection required during handling and installation.
