• The logic uses an Internal Relay (R100.0) to remember the state.
• The coil ( ) for R100.0 turns ON if:

  FANUC FAPT Ladder is the specialized engineering software used to create, edit, and maintain the Programmable Machine Controller (PMC) logic that powers FANUC CNC systems. While modern users often refer to it as FANUC Ladder-III, the "FAPT" (Fanuc Automated Programming Tool) branding remains a hallmark of its evolution from legacy DOS-based systems to the current Windows-based environment. The Core Role of FAPT Ladder Fanuc Fapt Ladder

  It is not a separate software, but a built-in machine tool builder's ladder programming and monitoring tool. Here are its key features: A very specific topic

  The Evolution: From FAPT to Ladder Editor III

  To fully understand the "Fanuc Fapt Ladder," you must understand its generational evolution, as this affects how you access it. The logic uses an Internal Relay (R100

  FAPT Ladder II – An improved version with better on-screen graphics, symbol tables, and support for higher-level PMCs (e.g., PMC-RB, RC). It introduced rudimentary commenting and cross-referencing.

  • If the CNC sends an M09 command (Coolant Off) via F7.1, it triggers a RESET coil (or a SET/RESET logic pair).
  • This forces R100.0 to OFF, which breaks the seal, turns off Y0.0, and stops the coolant.
