I. Basic Information

Model: JANCD-GMR24

Brand: Yaskawa (Yaskawa)

Origin: Japan

Type: High-end graphics processing board (Graphic Module)

Compatible System: YASNAC 3000G CNC (5-axis / multi-channel)

Main Control Board: Must be GMM22; Compatible with GMM12 (only for 3000G)

Board Form: Full-length industrial board, Slot2 slot

Original Part Number: DF7000065

II. Hardware Specifications

Power Supply: Backplane direct supply DC5V, approximately 25W

Display Resolution: 1024×768 (VGA color), up to 1280×1024

Graphics Capability: 3D tool trajectory, 3D processing simulation, multi-window display, dynamic tool path preview, 5-axis synchronous display

Temperature: Working 0℃~+55℃; Storage −25℃~+85℃

Humidity: 30%~95% RH (no condensation)

III. Board Interface (CN1~CN4)

CN1: System bus → Connects to GMM main control, high-speed data interaction

CN2: Display output → Color VGA display / LCD

CN3: Panel interface → MDI keyboard, operation panel signals

CN4: Expansion interface → Ethernet / DNC communication, data backup

Indicators (Front)

PWR: Power normal (always on)

RUN: Graphics processing in progress (flashes approximately 1Hz)

ALM: Display / Communication alarm (always on)

DSP: Data transmission (flashes)

IV. Pairing Rules (Strict)

✅ GMM22 (8 axes / 1MB) → Must be paired with GMR24 (3000G high-end)

✅ GMM12 (6 axes / 512KB) → Can be paired with GMR24 (3000G upgrade)

❌ GMM11 (4 axes / 256KB) → Cannot use GMR24; can only use GMR22

V. Core Differences from GMR22

GMR22: 640×480, 2D, 18W, equipped with GMM11/12, economical type

GMR24: 1024×768, 3D, 25W, equipped with GMM22, high-end type

VI. Common Faults

No color / color deviation: CN2 contact failure, VGA cable damage, display chip failure

3D simulation lag: Insufficient memory in GMM22, program too large, insufficient bus bandwidth of CN1

ALM indicator always on: Incompatible firmware versions of GMM/GMR, board aging
