1. General Description

2. Basic Information

• Model: JANCD-MRT1B

• Manufacturer: Yaskawa Electric (Yasnac/Motoman)

• Type: Servo control / axis interface PCB

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

• Status: EOL / Discontinued

• Common Similar Model: JANCD-MRY01B (related servo board)

3. Technical Specifications

• Power: 5 VDC / 24 VDC from controller backplane

• Axes Supported: Up to 6 axes of servo control

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

• Operating Temp: 0 °C to +40 °C

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

• Mounting: Internal slot in XRC/MRC controller cabinet

4. Key Functions

• Motion Control: Executes position, speed, and torque commands for servo axes

• Servo Interface: Manages real‑time communication between CPU and servo amplifiers

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

• Multi‑Axis Coordination: Synchronizes up to 6 axes for complex robot trajectories

• System Integration: Works with JANCD‑MCP01/MCP02 CPU boards in XRC/MRC systems

5. Compatibility

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

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

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

6. Installation & 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
