| 摘 要： | 一台HS-200BZ型实验室杯型砂轮自动磨样机砂轮转动正常,磨样机构水平移动也正常,但砂轮磨头始终不能上下移动。检查上下进给机械部分正常无卡阻,但是通电后步进电机始终不工作。在检查电控部分时发现,步进电机驱动器(MS-2HO-90M)无55V交流供电电源,但供电变压器本身输出55V电压正常,最后确认是保护部分UF11熔断器发生断路。在更换之后试运行,磨样机恢复正常。

| Abstract: | A HS-200BZ laboratory cup wheel automatic grinding machine is used, and its grinding wheel as well as horizontal movement works normally, but the grinding head cannot move up and down. The upper and lower feed machinery part works normal without jamming, but with active electricity the stepping motor does not work. By checking the electric control part, it can be found that there is no 55V AC power supply for stepping motor driver (MS-2HO-90M), and the power supply transformer output of 55V voltage is normal. Fianlly, it is confirmed that the break of UF11 fuse in protection section occurs. After the replacement and the trial operation , the grinding machine works normally. |
