且工作正常，证明数控装置的位置反馈信号接口电路无故障。但操作数控系统，手动移动X轴，机床Y轴不运动，同时数控显示“ERR21，X轴测量系统错误”报警。由此确认，报警是由位置测量系统不良引起的，与数控装置的接口电路无关。检查测量系统电缆连接正确、可靠，排除了电缆连接的问题。利用示波器检查位置测量系统的前置放大器EXE601/5-F的Ual和Ua2、*Ua1和Ua2输出波形，发现Ua1相无输出。进一步检查光栅输出(前置放大器EXE601/5-F的输入)信号波形，发现Ie1无信号输入。检查本机床光栅安装正确，确认故障是由于光栅不良引起的：更换光栅LS903后，机床恢复正常工作。故障现象：某配套SIEMENSPRIMOS系统
