例1 [机型] V-95C [现象]不能装带,只要一通电,便立即加载,加载完毕,自动保护断电,显示屏无任何显示。 [分析与检查]通电即加载,说明电源部分和加载驱动部分等都正常。首先检查方式开关位置与出盒停止位置,经仔细核对标记号位置,都正常,排除了是方式开关和机械错位造成该故障。接着检查伺服电路IT01(ZC93190P)各脚电压,发现⑦(工作电压输入)只有2V(正常时为4.9V)。顺此线路检查,发现此电
Example 1 [Model] V-95C [Phenomenon] Can not be loaded, as soon as it is energized, it is loaded immediately. After loading, automatic power-off protection is displayed without any display. [Analysis and inspection] Power is loaded, indicating that the power part and load the driver part are normal. First check the mode switch position and out of the box to stop the position, after careful check mark location, are normal, ruled out the way the switch and mechanical dislocation caused the fault. Then check the servo circuit IT01 (ZC93190P) the voltage of each pin and found ⑦ (operating voltage input) only 2V (normal 4.9V). Follow this route check and found this electricity
