1. General Description

2. Basic Information

• Model: JANCD-MRY01 (common variants: ‑1, ‑3, MRY01B)

• Manufacturer: Yaskawa Electric (Yasnac/Motoman)

• Type: Servo motion control PCB

• Applicable Systems: Motoman XRC / MRC robots, Yasnac LX‑1 CNC

• Status: EOL / Discontinued

• Related Model: JANCD-MRT1B (similar servo board, different connector layout)

3. Technical Specifications

• Power: 5 VDC / 24 VDC (backplane supplied)

• Axes: Up to 6 axes of coordinated servo control

• Communication: Proprietary high‑speed servo bus (XRC/MRC)

• Operating Temp: 0 °C to +40 °C

• Humidity: 5%–80% RH (non‑condensing)

• Dimensions (MRY01B): ~250 × 140 × 30 mm; weight ~1.2 lb (0.54 kg)

4. Key Functions

• Motion Execution: Position, speed, torque control for servo axes

• Servo Interface: Real‑time link between CPU (MCP01/MCP02) and servo amplifiers

• Feedback Processing: Reads encoder/resolver signals for closed‑loop control

• Multi‑Axis Sync: Coordinates up to 6 axes for complex robot trajectories

• System Integration: Works with XRC/MRC CPU and memory boards (MM01C, MMM01/02/04)

5. Compatibility

• ✅ Motoman: XRC / MRC robot controllers (primary use)

• ✅ Yasnac: LX‑1 CNC (machine tool motion)

• ❌ Not compatible: DX/FS/YRC robots, newer JANCD‑Yxx boards, non‑Yaskawa systems

6. Installation & ESD Safety

• Power OFF controller before installation; no hot swap

• Use grounded ESD wristband (static‑sensitive components)

• Align edge connector, insert firmly into dedicated slot, secure screws

• Operate in clean, dry, vibration‑free industrial environment

• Do not disassemble or modify; repair only by qualified technicians

7. Variants Notes

• JANCD-MRY01‑1: Standard version for XRC/MRC

• JANCD-MRY01‑3: High‑density variant, same form/fit/function

• JANCD-MRY01B: XRC‑specific, relay outputs for auxiliary control
