I. Product Overview

Model: JANCD-GIF02 (also known as GIF02, GIFO2)

Brand: YASKAWA (Yaskawa)

Category: CNC Expansion Interface Board (Handwheel / Panel-specific)

Compatible System: YASNAC 2000G / 3000G (suitable for Mori Seiki and other machine tools)

Material Code: DF8200089; Version: REV.C

Status: Factory discontinued, market mainly consists of disassembled / refurbished parts

II. Core Functions

Handwheel (MPG) Signal Processing: Special handwheel interface, supports 2-axis / 3-axis handwheel

Expansion I/O: Supplements the basic I/O board (GI0/GIO01) points, compatible with additional machine tool panels

Panel Button / Indicator Light Driving: Matrix scanning and driving of the machine operation panel

Signal Isolation and Filtering: Photoelectric isolation + RC filtering, resistant to workshop interference

With GIO01/GFG01/GFL01: Expands system I/O capacity and interface type

III. Technical Parameters

Structure: Half-long card (220×140mm), gold finger slots

Interfaces: 2 handwheel DB9 / terminal blocks, panel I/O connector, system bus gold finger

Handwheel Specifications: 5V/12V compatible, RS-422 differential signal

I/O Expansion: 16DI/16DO (photoelectric isolation, DC24V)

Power Supply: Backplane DC5V (logic), power consumption approximately 8W

Temperature: Working 0–55℃, storage **-20–70℃**

Weight: Approximately 0.6kg 

IV. Model Positioning (GIF vs GI0)

GIF02: Expansion interface board, focusing on handwheel + panel-specific I/O, not replacing the basic I/O

GI0/GIO01: Basic I/O board, providing 32/64 points of general DI/DO

Combination usage: CPU + GIO01 (basic I/O) + GIF02 (handwheel / panel) + GFG/GFL (communication)

V. Installation and Faults

Installation: The free slot on the right side of the CPU board, adjacent to GIO01; differential shielding for handwheel lines and grounding

Common faults: Handwheel no response, panel buttons malfunction, gold fingers oxidized, differential signal interference
