从符号、线号、页次到主回路、控制回路，再到 PMC 地址怎么对应回图纸上的那根线——手把手教你把一张数控机床电气原理图读明白，并顺着报警号反查故障点。

A practical method for reading any CNC electrical schematic - common symbols and designations, wire/sheet numbers as coordinates, how to read the power and control circuits, and ho...

海德汉 TNC 的刀具管理靠两张表：TOOL.T 存每把刀的长度/半径/寿命，TOOL_P.TCH 存刀库每个刀套对应哪把刀。本文讲清两张表怎么填、L/R 刀补怎么自动生效、刀具寿命怎么设，以及 tool_p.tch 读...

HEIDENHAIN TNC manages tools with two tables: TOOL.T holds each tool's length/radius/life, TOOL_P.TCH maps each magazine pocket to a tool. This guide explains both tables, how L/R ...

撞刀后先保现场：别回零、别清报警、别动工件、别改参数，拍三张照片记 G54 与刀补。再按机械/参数坐标系/程序操作三分排查，最后回零对刀空运行复校，并用对刀仪、仿真、软限位、首件单段四件...

FANUC 一键设定（参数设定支援）把轴数/轴名/轴号一次配好，伺服初始化（SV SET）按电机 ID 2020 自动算脉冲数/齿轮比/方向，FSSB 自动设定（1902#0）认放大器。本文讲清三步顺序与 417/5136/PW...

FANUC One-Touch Setting (Parameter Setting Support) sets axis count/name/assignment at once; Servo Initialization (SV SET) computes pulses/gear/direction from motor ID 2020; FSSB a...

PMC 强制输出（FORCE）能在不依赖梯形图逻辑的情况下把信号强行钉在 1/0，用来判断'是阀坏了、线断了还是逻辑没到'。本文讲清入口 PMC→PMCDGN→STATUS→FORCE、可强制地址 G/R/C/A/T/E/D/Y 与 ...

FANUC PMC force output (FORCE) pins a signal to 1 or 0 regardless of ladder logic, telling whether 'the valve is bad, the wire is broken, or the logic never arrived'. This guide co...

总线掉站别急着换模块：FANUC I/O Link 是链式串联，断一站后面整串全掉，报警点名的站往往不是坏的那个；PROFIBUS-DP 看 BF 灯闪烁（掉部分站）还是常亮（整段瘫）。本文讲清 ER97 的 CH/GROUP...
