✅ Replacement Rules

Fully Replaceable with FC250: Pin / Installation / Program Compatibility, Direct Replacement (Requires Firmware Update)

Downward Compatibility: Can be used for the original FC250 Configuration, Automatically Identify and Enable High-Performance Mode

Incompatible with Old Systems: Only I80/I80M, Cannot be Used for I60/C70

IV. Common Fault Phenomena

High-speed Machining with Large Profile Error / Jitter → CPU Frequency Aging or Interpolation Module Failure 12. Bus alarm during 12-axis expansion → CN21 interface damage or insufficient bandwidth

System high-temperature alarm (>55°C) → Poor heat dissipation or excessive environmental temperature

Slow program loading / Transmission timeout → Gigabit network port failure or Flash bad block
