第四轴加不上的本质不是参数多，而是 FSSB 轴数没告诉系统、轴名 ASCII 填错、1006#0 忘了置 1、柔性齿轮比算错。本文按硬件→FSSB→轴定义→伺服初始化→回零→PMC 六步走：给出 8130/1010/102...

Adding a fourth axis is rarely about having too many parameters - it usually fails because the FSSB axis count was never told to the control, the axis name ASCII is wrong, 1006#0 w...

主轴齿轮换挡（高低档）错得最多的是钳速参数名搞混（标准里没有 3734，最低钳速 3735、最高 3736）、3741-3744 与各档传动比算反、以及 PMC 侧 CTH1A/CTH2A 与 GR 信号没对应。本文按换挡方式...

Gear-shift setup breaks most often because the clamp-speed parameter names are confused (there is no 3734; minimum is 3735, maximum 3736), 3741-3744 is inverted against the gear ra...

749/750/751 都是 CNC 与主轴放大器之间的串行通讯报警，不是电机故障。750 是上电握手失败、749 是就绪后掉链、751 是放大器自身 AL-XX，三者排查起点完全不同。本文给时机区分、诊断 409 四位...

749, 750 and 751 are all serial communication alarms between the CNC and the spindle amplifier - not motor faults. 750 is a failed power-on handshake, 749 a dropped link after read...

三菱 M80 刀库乱刀的本质是系统记录的刀号与实际刀位对不上。不要照搬 M70 的 M77/M74/M79 维修代码，M80 的正确手段是 Setup 下的刀具登录逐位核对 + 主轴同步，再按信号/参数/机械三分法定位...

A scrambled tool magazine on a Mitsubishi M80 is not 'a tool loaded wrong': the recorded tool number no longer matches the physical pot. Do not copy the M70 M77/M74/M79 codes - the...

一页看完三菱 M80 刀库乱刀：按现象对号入座，主轴同步、T 登录四个位置、刀库刀具数据与刀具寿命的 R 寄存器地址一次列清。适合现场贴着机台用。

One page for a scrambled Mitsubishi M80 magazine: match the symptom, then act. Spindle sync, the four Tool Registration targets, and the magazine / tool-life R-register addresses a...
