I. Core Functions

CNC High-Speed Trajectory Calculation: Special calculation boards for interpolation, coordinate transformation, and forward control (pre-reading) in 3000G/2000G systems.

High-speed Data Transfer for Large Data Volume: High-speed caching and distribution of processing program segments, tool offsets, and coordinate data to reduce CPU load.

Multi-Axis Synchronization and Precision Compensation: Combined with GTU01 axis control board, it realizes multi-axis linkage synchronization and pitch/gear clearance compensation calculations.

System Bus Data Transfer: High-speed bus (10Mbps level) data protocol processing and forwarding by the CNC backplane.

Power Failure Data Protection: On-board SRAM and backup battery to save processing parameters and power-off coordinates.

II. Specifications and Parameters

Model: JANCD-HDP01 (Material Number usually DF820xxxx)

Compatible Systems: YASNAC 2000G, 3000G CNC Control Cabinet

Installation Slot: Backplane-specific Slot (commonly Slot4, adjacent to GTU01 Slot3)

Power Supply: Backplane DC5V ± 5%, Power Consumption ≤ 20W

Memory: On-board high-speed SRAM (approximately 1–2MB), used for trajectory caching

Interfaces: Gold Finger (backplane bus), CN1 (optional expansion I/F)

Environment: Operating 0℃–55℃, Storage - 25℃–85℃, Humidity ≤ 90% without condensation

Size/Weight: Standard JANCD Large Board (approximately 310×215mm), Weight approximately 0.9kg

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

Slot1: JANCD-GMM01 (Main Control CPU Board)

Slot2: JANCD-GMR01 (Display/Graphic Board)

Slot3: JANCD-GTU01 (Axis Control Board, you have checked)

Slot4: JANCD-HDP01 (High-Speed Data Processing Board, this board)

Slot5: JANCD-GSC01 (Logic I/O Board)

Slot6: JANCD-GSP01 (Operation Panel Interface Board)

IV. Common Faults and Replacement

Typical Faults: Processing Stalling / Step Loss, Trajectory Deviation, Bus Communication Error, Parameter Loss (Battery Failure).

Replacement Suggestions: Prefer to select refurbished with test report (matching 2000G/3000G system version); No original factory replacement available, cannot be interchanged with robot JANCD series (such as HA03).

V. Model Distinction

HDP01: YASNAC CNC for use (2000G/3000G), focusing on trajectory calculation / data caching.

HA03: Motoman Robot ERC Control Cabinet for use, focusing on kinematic calculation (you have checked the previous model).
