1. General Description

2. Basic Information

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

• Manufacturer: Yaskawa Electric (Motoman/Yasnac)

• Type: Servo motion + relay output PCB

• Primary System: Motoman XRC robot controller

• Secondary: MRC robots, Yasnac LX‑1 CNC

• Status: EOL / Discontinued

• Weight: ~0.86–1.0 kg

3. Technical Specifications

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

• Axes: Up to 6 axes servo control

• Onboard I/O: Relay outputs for brakes, valves, aux motors

• Communication: XRC/MRC high‑speed servo bus

• Operating Temp: 0 °C to +40 °C

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

• Form Factor: XRC internal slot (card cage mount)

4. Key Functions

• Servo Motion: Position/speed/torque commands for 6 axes

• Relay Outputs: Switches 24 VDC/120 VAC loads (brakes, grippers)

• Encoder Feedback: Reads incremental/absolute encoder data

• Real‑Time Sync: Coordinates 6‑axis robot motion

• System Interface: Works with MCP01/MCP02 CPU boards in XRC

5. Compatibility

• ✅ Motoman: XRC (main), MRC (limited)

• ✅ Yasnac: LX‑1 CNC (machine motion)

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

6. Installation & Safety

• Power OFF controller; no hot swap

• Use grounded ESD wristband (static sensitive)

• Align edge connector, insert firmly, secure screws

• Operate in clean, dry, low‑vibration environment

• Repair only by qualified Yaskawa technicians

7. Variants

• JANCD-MRY01B‑1: Standard XRC version

• JANCD-MRY01B‑3: High‑density relay variant

• JANCD-MRY01: Non‑relay servo‑only version (no aux outputs)

8. vs. JANCD-MRT1B

• MRY01B: XRC‑optimized, relay outputs, 6‑axis servo

• MRT1B: XRC/MRC/LX‑1, no relays, pure servo control
