Do not swap modules the moment a station drops. FANUC I/O Link is a daisy chain: one break takes out everything downstream, so the station named in the alarm is usually not the fau...

回零失败别再靠换件试：先分成'找不到参考点'和'参考点位置不正确'两大类。前者再看回零时有没有减速动作——无减速查减速开关与接线，有减速仍失败查编码器一转信号；后者按偏差形态区分 1850 ...

Stop swapping parts to see what sticks. Split homing failures into two classes: reference not found, and reference position wrong. In the first class, watch whether the axis decele...

尺寸忽大忽小别再靠反复调刀补硬压 —— 刀补只修稳定的系统偏差，修不了随机漂移。用四条线分离法先判断「变化跟着什么走」：随件数走是刀具磨损，随时间走是热变形，随位置走是丝杠/螺距，随...

刚性攻丝调不好的根子，多半不是编程而是参数。本文把 5200–5294 按五类拆开讲：开关位决定走不走刚性攻丝、齿轮比 5221–5224/5231–5234 决定比例、转速上限是 5241–5244（不是 5200）、增...

Bad rigid tapping is usually not the program - it is the parameters nobody explained. This guide splits the 5200-5294 group into five blocks: enable bits that decide whether you ta...

可直接对着机床抄的 FANUC 刚性攻丝参数速查表：5200–5294 按五段归类（开关位 / 齿轮比 / 转速上限 5241–5244 / 增益与时间常数 / 偏差极限），逐条给出含义与常用设定；附诊断号 452/453/45...

A copy-straight-to-the-machine Fanuc rigid tapping reference: 5200-5294 grouped into five blocks (enable bits, gear ratio, speed limit 5241-5244, gains and time constants, deviatio...

模拟主轴的坑不在参数多，而在启用链顺序错、3730 与 3731 填反、JA41 编码器 A/B 接错。本文按接线→启用链→电压标定→功能验证四步走：给出 3717 填 0 时无报警却不转的原因、3731 先 3730 ...

An analog spindle is rarely beaten by the number of parameters. It is beaten by a wrong enable order, 3730 and 3731 swapped, or an inverted coder phase on JA41. Four stages in orde...
