Model Definition

• JANCD: Yaskawa CNC/robot control board series

• 10: 10‑series high‑speed I/O & servo platform

• 03: 3rd‑gen hardware (high‑density I/O + servo processing)

• C: Upgraded industrial grade (reinforced isolation, extended temp, ESD/surge hardening)

Technical Specifications

Electrical

• Power Consumption: ≤ 40 W

• Isolation: Optocoupler, 1500 V AC withstand

• Digital I/O: 64‑in / 32‑out (24 V DC, sink/source selectable)

• Output Rating: 0.5 A/channel, 16 A total max

• Encoder: Differential A/B/Z‑phase (MDD/MKD compatible)

• Logic/Field: 5 V DC / 24 V DC

Communication & Interfaces

• System Bus: High‑speed backplane, 20 Mbps

• I/O Connectors: 3 × 50‑pin ribbon ports (J1/J2/J3)

• Expansion: U1 slot (analog I/O or PROFIBUS)

• Diagnostics: 16‑LED array (power, run, alarm, comms, I/O status)

Mechanical & Environmental

• Cooling: Natural convection (fanless)

• Protection: IP20

• Operating Temp: −10 °C to +55 °C (wider than 1003B)

• Storage Temp: −30 °C to +85 °C

• Humidity: 10%–85% RH (non‑condensing)

• Dimensions (W×H×D): 245 mm × 155 mm × 30 mm

• Weight: ~0.7 kg

Key Differences (1003C vs 1003B)

• Temperature Range: 1003C extends low end to −10 °C (vs 0 °C)

• Surge/ESD: Enhanced TVS diodes and PCB shielding for better noise immunity

• Signal Integrity: Refined encoder circuit for lower jitter at high speeds

• Lifecycle: C‑revision components for longer MTBF and obsolescence mitigation

Applications

• YASNAC i80/i90 CNC machine tools (milling, turning, machining centers)

• Motoman NX100/XRC robot controllers (welding, handling, assembly)

• Multi‑axis automation (printing, packaging, textile machinery)

• Retrofits & replacements for legacy Yaskawa systems

Compatibility & Installation

• Direct Swap: Pin‑to‑pin compatible with JANCD-1003B; no wiring changes required

• Software: Configured via Yaskawa MotionWorks (same as 1003B)

• Mounting: Standard rack‑mount; fits existing 10‑series slots
