FANUC 报警 459「HI HRV SETTING ERROR / 高速 HRV 设定错误」由伺服轴号（参数 1023）相邻的奇-偶轴对引起：一台 SVM 支持高速 HRV、另一台不支持。本文讲清根因、定位方法、处理步骤，并区分 ...

FANUC alarm 459 'HI HRV SETTING ERROR' is raised when two axes whose servo axis numbers (parameter 1023) are an odd/even pair have mismatched high-speed HRV capability — one SVM s...

828D 接变频器 / 模拟驱动时，要把轴配成「模拟轴（模拟量给定输出）」而不是数字轴。本文给出 MD30100 / 30110 / 30120 / 30130 / 30134 与 MD30200 / 30220 / 30230 / 30240 的取值口径，X252...

When an 828D drives an inverter or analog drive, the axis must be configured as an analog (analog setpoint output) axis rather than a digital one. This guide gives the values for M...

海德汉 TNC 报「防护门未关 / DOOR OPEN / GUARD NOT CLOSED」，本质不是 NC 软件故障，而是 PLC 把「门关闭条件」判成 false。本文按安全链四层（门开关机械 → 安全继电器 → PLC 数字量输入 ...

When a Heidenhain TNC reports 'guard doors are open' / 'DOOR OPEN' / 'GUARD NOT CLOSED', the root cause is not faulty NC software - the PLC has evaluated the door-closed condition ...

828D 换完伺服电机或编码器，轴上电后往往报 25022「轴编码器警告 0」或直接要重新回零——丢的不是程序，而是「编码器零点与机床零点之间的对应关系」。本文按官方 Function Manual 给出增量式...

After swapping a servo motor or encoder on an 828D, the axis often comes up with alarm 25022 'Axis Encoder Warning 0' or demands referencing again. What was lost is the corresponde...

FANUC 备份分三条路：0i-F / 0i-F Plus 的一键全备份必须走两段并断电重启一次；BOOT 画面下的 SRAM 备份先于 NC 启动、不受报警影响、可整块恢复；单项数据走各自画面的 PUNCH→EXEC，每次只输...

FANUC backup has three routes: the 0i-F / 0i-F Plus one-click full backup runs in two stages and needs one power cycle; the BOOT-screen SRAM backup starts before the NC, needs no p...
