1. General Information

• MPN: JANCD-SV03

• Material No.: DF8202724 (Rev. A03 common)

• Manufacturer: Yaskawa Electric (Motoman Robotics)

• Application: XRC robot controllers (6–8 axis systems, as single‑axis expansion)

• Status: Obsolete (discontinued); available as refurbished, used, or new old stock (NOS)

2. Electrical & Physical Specifications

• Supply Voltage: 24 VDC (from XRC backplane)

• Current Consumption: Up to 2 A (lower than SV02 series, for single‑axis operation)

• Control Axis: 1 independent servo axis

• Control Method: PWM‑based, full closed‑loop (position/speed/torque)

• Dimensions: 310 mm × 170 mm × 20 mm

• Weight: ~0.1 kg

• Operating Temperature: 0 °C to 40 °C

• Humidity: ≤80% (non‑condensing)

3. Interfaces & Features

• Motor Power: 1‑axis servo motor power terminals

• Encoder: 1‑channel encoder input (incremental/absolute supported)

• I/O: Limit, home, and emergency stop signals

• Bus: XRC proprietary backplane bus (communicates with CPU board JANCD‑XCP01)

• LEDs: Power, run, and fault indicators

• Protection: Overcurrent, overvoltage, overtemperature, short‑circuit, encoder fault protection

4. Compatibility

• Compatible With: Motoman XRC controller series (all models)

• Matched Boards: JANCD‑XCP01 (CPU), JANCD‑XEB01 (backplane), JANCD‑XIO (I/O)

• Not Compatible With: ERC, NX100, DX, YRC controllers; LX/MX CNC systems

• Role: Used alongside SV02/SV02B/SV02C in XRC systems to expand axis count (e.g., 2×SV02 + 1×SV03 = 5 axes)

5. Functional Overview

• Receives motion commands from the XRC CPU via the backplane bus.

• Drives one AC servo motor with PWM power output.

• Closes the control loop using encoder feedback for high‑precision positioning.

• Triggers protective shutdown and alarm reporting under fault conditions.

• Designed for single‑axis expansion in XRC robot systems where 2‑axis boards are insufficient.

6. Key Differences from SV02 Series

• SV02/SV02B/SV02C: 2 axes, up to 5 A, higher power for main robot axes.

• SV03: 1 axis, up to 2 A, lower power, for auxiliary or additional axes in XRC systems.

7. Availability & Notes

• Officially discontinued by Yaskawa; only refurbished/used/NOS units available on the market.

• When replacing, verify DF8202724 revision and backplane slot compatibility.
