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 ...

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...

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...

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...

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...

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...

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...

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 ...

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...

二手加工中心验收最容易踩的坑在电气。这份 30 项现场检查清单，从履历核对、断电检查、上电测试到隐瞒手段识别，帮你在付尾款前把问题找出来。
