I. REV.D Revision Highlights (Compared with REV.C/C0)

REV.D: The final production stable version, fixes the occasional overflow and high-temperature drift issues in REV.C

Optimizes the onboard power filter, enhances the long-term stability at high temperatures (45–55℃)

Strengthened the reliability of the gold fingers and the backplate contact, reduces communication errors in vibration environments

Functionally compatible with REV.C, can be directly interchanged

II. Core Functions (Same as HA03 Series)

High-speed trajectory calculation: Joint interpolation, coordinate transformation, forward/inverse kinematics solution

Floating-point and logic-intensive calculations: Reduces the burden on CPU (CP0x), improves trajectory response

Robot synchronous/coordination movement: Point welding / arc welding / handling of complex paths

Special for ERC control cabinet: Composed with CP0x, IO0x, and BK01 as the main control unit

III. Specifications and Parameters

Dimensions: Approximately 310 × 215 × 35 mm (standard JANCD large board)

Weight: Approximately 0.8–0.9 kg

Power supply: Backplate DC5V ±5%, power consumption ≤15W

Operating temperature: 0℃～55℃; Storage: -25℃～85℃

Interface: Gold fingers on both sides, connects to the ERC main control backplate

IV. Typical Configuration (ERC Control Cabinet)

Slot1: JANCD‑CP0x (CPU main control)

Slot2: JANCD‑HA03 REV.D (High-speed calculation)

Slot3: JANCD‑IO0x (I/O interface)

Slot4: JANCD‑BK01 (Backup battery / storage)
