I. Core Functions

High-speed I/O Control: Managing the high-speed signal interaction between CNC and external devices (panel, sensor, solenoid valve)

External Data Preprocessing: Caching and distribution of processing programs, macro variables, and tool compensation data, reducing CPU load

Multi-axis Synchronous Signal Processing: Coordinated with GTU01 axis control board, processing feedback and instructions for synchronous, spindle, and indexing axes

System Bus Bridging: Connecting CNC backplane bus and external I/O modules, enhancing communication bandwidth

Machine Auxiliary Functions: M/S/T code processing, emergency stop / overtravel / interlock logic operations

II. Specifications and Parameters

Compatible Systems: YASNAC 2000G, 3000G CNC (such as Shengjing Machine Tools)

Board Card Shape: Standard JANCD large board (approximately 310×215mm)

Version: REV.C (most common, stable version)

Material Number: DF6203438 (printed on the edge of the board)

Power Supply: Backplane DC5V, power consumption ≤ 18W

Interfaces: Gold fingers (backplane bus), CN1/CN2 (external I/O)

Environment: Operating 0℃–55℃, Storage - 25℃–85℃

Weight: Approximately 0.8kg

III. Board Card Matching in the Same Cabinet (2000G/3000G)

Slot1: JANCD-GMM01 (CPU main control)

Slot2: JANCD-GMR01 (display / graphics)

Slot3: JANCD-GTU01 (axis control board, you have checked)

Slot4: JANCD-HDP01 (high-speed data processing, you have checked)

Slot5: JANCD-HSP01 (high-speed I/O processing, this board)

Slot6: JANCD-GSC01 (logic I/O)

IV. Common Faults and Replacement

Typical Faults: I/O response delay, M code not executed, external device communication errors, random processing stops

Replacement Key Points: Prioritize REV.C version, need to match the system software version; cannot be exchanged with the robot JANCD series (such as HA03)
