1. General Description

2. Basic Specifications

• Compatible System: YASNAC I80 / I80M (Turn/Mill, high-end)

• Backplane: JANCD-FC001 (1 full slot)

• Dimensions: 267 × 140 mm (form-factor compatible with FC610/FC620)

• Power Supply: DC 24 V ±10%, 1.0 A (higher than FC620)

• Operating Temperature: 0 °C to +45 °C

• Storage Temperature: −20 °C to +60 °C

3. Key Features (vs. FC610 / FC620)

A. Spindle Control (Highest Performance)

• 2 independent high-speed spindle channels (αi-B / βi-B / αi-F compatible)

• Response time ≤1.0 ms (FC620: ≤1.5 ms; FC610: ≤2 ms)

• Positioning accuracy ±0.0001° (FC620: ±0.0005°)

• Dual-spindle synchronous control (for tandem spindle applications)

B. Servo Axis Expansion

• Adds 2 high-precision servo axes (max system axes: 8)

• Servo loop update 1.5 kHz (FC620: 1.2 kHz; FC610: 1 kHz)

• Advanced gantry synchronization (dual-motor, real-time error correction)

• Linear motor compatibility (direct-drive systems)

C. High-Speed Communication

• CN61 bus to FC500 at 12 Mbps (FC620: 10 Mbps)

• Alarm response ≤0.5 ms

• Full compatibility with FC510 (memory), FC520 (communication), and FC6xx series

4. System Configuration & Compatibility

Mandatory Boards

• CPU: FC251 (required for full performance; FC250 limited)

• PLC Core: FC500 (mandatory)

• Expansion: FC510 (opt), FC520 (opt)

• Backplane: FC001 (min. 4 full slots recommended)

Typical Setup

• 6-axis high-precision machining center: FC251 + FC500 + FC510 + FC520 + FC630 + FC440

• 8-axis multi-spindle turn-mill: FC251 + FC500 + FC630 ×1 + custom I/O

Limitations

• Max 1 × FC630 per system

• Occupies 1 full slot; cannot coexist with FC610/FC620

5. Common Faults & Alarms

• A.630 Spindle Bus Critical Error: CN61 connection fault, FC500 communication timeout, or bus IC failure

• Spindle Synchronization Loss: Encoder signal mismatch, dual-spindle parameter drift

• Servo Loop Overflow: Axis tuning mismatch, high-load oscillation

• No LED Indication: 24V power failure, internal fuse (F1) blown, or backplane contact issue

6. Applications

• Ultra-precision 6–8-axis turn-mill centers (dual spindle + B/C/A axes)

• Multi-spindle automated production lathes (3+ spindles)

• High-speed gantry machines (linear motor / dual-motor sync)

• Legacy I80 system performance upgrades (max spindle/servo speed)
