1. General

• Model: JANCD-SV02 (variants: SV02B, SV02C)

• Type: Servo Amplifier / Motion Control PCB (backplane slot card)

• Manufacturer: Yaskawa Electric (Motoman Robotics)

• System: Motoman XRC robot controller (6–8 axis robots)

• Function: Axis servo drive & motion control (position/velocity/torque loops)

• Status: Obsolete / discontinued

2. Specifications (JANCD-SV02)

• Power: 24 VDC (rated 3.0 A; SV02B: 5.0 A max)

• Axes: Controls 1–2 servo axes (XRC system, paired with other SV boards)

• Control Method: PWM (Pulse Width Modulation)

• Interfaces:

  • Servo motor power & encoder feedback

  • Backplane bus (XRC rack)

  • Limit/home signals, emergency stop

  • LED status indicators

• Dimensions: 310 × 160 mm; weight ~0.6–1.3 lbs

• Environment:

  • Operating: 0 °C to 40 °C

  • Humidity: ≤80% (non-condensing)

  • Altitude: ≤1,000 m above sea level

3. Key Features

• XRC Servo Core: Drives Motoman XRC robot joints (AC servo motors) with high accuracy

• Closed-loop control: Full position/velocity/torque servo loops for smooth motion

• Compact design: Slim PCB for XRC rack mounting; SV02B/SV02C are drop-in upgrades

• Diagnostics: Onboard LEDs for power, fault, and axis status; supports XRC system alarm codes

• Protection: Overcurrent, overvoltage, overheat, and short-circuit protection

4. Compatibility

• Designed for: Motoman XRC robot controllers (all XRC robot models)

• Works with:

  • CPU board: JANCD-XCP01 series

  • Backplane: JANCD-XEB01 series

  • I/O boards: JANCD-XIO series

• Not compatible: ERC, NX100, DX, YRC, or LX/MX CNC systems

• Replacement: SV02 → SV02B → SV02C (pin-compatible, improved reliability)
