1. Basic Product Information

• Brand & Model: Yaskawa Electric, JANCD‑CG26 (also JANCD‑CG26‑H)

• Part Number: DF8202775‑C0 (alternate OEM part)

• Product Type: CNC Graphic/Memory Expansion PCB / Control Board

• Compatible Systems: YASNAC M‑II, XRC, PC NC, and other legacy Yaskawa CNC platforms

• Origin: Japan

• Weight: Approx. 1.0 kg (2.2 lb) (JANCD‑CG26‑H: 2.70 lbs / 1.22 kg)

• Status: Discontinued by manufacturer (available as new/refurbished industrial spare)

2. Core Functions & Technical Features

Primary Functions

• Graphics Processing & Display Control: Handles CNC UI rendering, coordinate path visualization, machining trajectory preview, and real‑time status display (upgraded from CG23/CG24).

• Memory Expansion: Provides dedicated RAM/ROM for CNC system data storage, program buffering, and motion logic caching.

• System Bus Communication: Interfaces with main CPU, operator panels, servo drives, and I/O modules via internal CNC bus.

• Fault Diagnosis & Monitoring: Supports self‑diagnosis, alarm output, and status monitoring for the CNC graphics/memory subsystem.

Key Technical Characteristics

• High‑integration dedicated architecture for legacy CNC graphics and memory tasks.

• Industrial‑grade design for harsh environments (dust, vibration, temperature variation).

• Built‑in overcurrent, overvoltage, undervoltage, and thermal protection circuits.

• Plug‑and‑play replacement for legacy CG‑series boards (CG23/CG24/CG26).

3. Typical Applications

• Legacy YASNAC CNC machine tools (milling, lathe, grinding, etc.).

• Industrial automation equipment requiring legacy CNC graphics/memory expansion.

• Retrofit and maintenance of aging Yaskawa CNC systems (direct replacement for CG23/CG24).

4. Safety & Installation Notes

• Power Safety: Disconnect main power before installation/removal; wait ≥5 minutes for residual voltage discharge.

• Grounding: Ensure proper system grounding (≤100 Ω) for EMC and safety.

• Thermal Management: Maintain adequate ventilation; avoid mounting near high‑heat components.

• Handling: Use ESD protection during installation to prevent component damage.

5. Availability & Support

• Condition: New, refurbished, or used (industrial spare parts).

• Warranty: Typically 90–24 months from industrial suppliers.

• Support: Limited manufacturer support; third‑party repair and refurbishment services available.
