Primary Functions

• Graphic Display Control: Renders CNC system UI, coordinate path visualization, machining trajectory preview, and real‑time status display.

• Motion Logic Assistance: Assists main CPU in multi‑axis motion interpolation, position closed‑loop control, and servo command forwarding.

• Internal Bus Communication: Provides system‑level bus interfaces to connect display units, operator panels, servo drives, and I/O modules.

• Fault Diagnosis: Supports system self‑diagnosis, alarm output, and status monitoring for CNC graphics subsystem.

Key Technical Characteristics

• High‑integration dedicated graphics processing architecture for CNC environments.

• Stable performance under industrial harsh conditions (dust, vibration, temperature variation).

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

• Plug‑and‑play expansion design for easy replacement of faulty graphic boards in machine tools.

3. Typical Applications

• CNC machine tools (milling, lathe, grinding, etc.) with YASNAC control systems.

• Industrial automation equipment requiring high‑precision motion control + graphic HMI.

• Legacy CNC system retrofitting and maintenance (direct replacement for JANCD‑CG23 series).

4. Safety & Installation Notes (English)

• Thermal Hazard: Heatsink may reach high temperatures during operation; allow ≥15 minutes cooling before servicing.

• Electrical Safety:

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

  • Ensure proper grounding (≤100 Ω) for the CNC system and control cabinet.

• Environment: Install in dry, non‑condensing, vibration‑free locations; separate high‑voltage and low‑voltage cables.
