I. Basic Information

Material Number: DF9200710-A0 (Exclusive to FC242)

Compatible System: YASNAC I80 / I80M Full Series CNC (Must be paired with FC230B)

Assembly Backplate: JANCD-FC001 (Standard Backplate for I80)

Board Card Size: 267 × 152 mm (General Size for I80)

Weight: Approximately 0.32 kg

Power Supply: DC 5V ±5%, approximately 1.5 A (Backplate Power Supply, Power Consumption ≈ 7.5W)

Operating Temperature: 0°C ~ +55°C

Version: Rev.A (Unique Hardware Version, No Derivative Models)

II. Core Functions (FC240 Enhanced Version)

High-speed Multi-Axis Data Routing (Core Upgrade)

Designed specifically for ultra-large-scale axis groups with more than 12 axes, sharing the data load of FC230B

Manages 12-axis servo + 3-axis spindle instructions / feedback data, with bandwidth increased by 30% compared to FC240

Bus Rate: 130 Mbps, Supports Hard Real-Time Transmission of Real-Time Data

Enhanced Expansion Interfaces

CN28: Servo Expansion Interface (6 Axes, FC240 is 4 Axes)

CN29: Spindle Expansion Interface (3 Axes, FC240 is 2 Axes)

CN30: High-Speed Parallel Bus with FC230B (64-bit), Delay < 1μs

Signal Processing and Anti-Interference (Enhanced)

Full Channel Photoelectric Isolation + Differential Filtering, EMI Protection Level Enhancement

Supports Long Distance (Up to 50m) Servo Bus Transmission, Signal No Decrement

Onboard Hardware Data Verification, Transmission Error Rate Reduced to 10⁻⁹

System Monitoring and Diagnosis (Enhanced)

Onboard 6-Lane LED Status Lights (Power, Bus, Transmit, Receive, Error, Ready)

Real-time Monitoring of Bus Timeout, Data Verification Error, Signal Loss, Axis Synchronization Offset

Precise Fault Code Location to Channel Level, Facilitating Quick Troubleshooting

Cascading Expansion Capability

I80 System Supports Up to 3 FC242 Cascades, Maximum Expansion to 24 Axis Servo + 6 Axis Spindle

Cascading Automatically Allocates Bandwidth, No Data Bottleneck

III. Compatibility and Pairing

✅ Required Board Cards (High-end Extended Configuration for I80)

CPU Board: JANCD-FC200 (SMON Main Control Board)

Motion Management Board: JANCD-FC230B (MMON, Core, Must)

Data Distribution Board: JANCD-FC242 (DDB, High-End Extended)

Servo Interface Board: JANCD-FC226 (Signal Conversion)

PLC Board: JANCD-FC210 / FC211

✅ Replacement and Compatibility Rules

Fully Compatible with FC240: Pin / Installation / Program / Parameters Common, Can Be Directly Replaced

More Powerful Performance: Higher Bandwidth, More Axes, Better Anti-Interference

Incompatible with Old Systems: Only for I80/I80M, Does Not Support I60/C70

No Alternative Models: Exclusive High-End Extended Board for I80, No Other Compatible Models

IV. Common Fault Phenomena

System Reports "Insufficient Servo Bus Bandwidth" → FC242 Bandwidth Module Aging or Overload

Random Step Loss / Alarm for Extended Axes (After 7 Axes) → Poor Contact of CN28/CN29 Interface or Differential Circuit Damage

Profile Distortion (High Speed) During Multi-Axis Interpolation → FC242 Data Distribution Delay or Verification Circuit Failure

System Startup Reports "DDB Board Version Mismatch" → Inconsistent Firmware Versions of FC242 and FC230B
