电机马达维修_技术支持无拔刀动作，分析原因，有几种可能：SQ2无信号，所以未输出松刀电磁阀YV2的电压，主轴仍处于抓刀状态，换刀臂不能下移。松刀接近开关SQ4无信号，则换刀臂升降电磁阀YVl状态不变，换刀臂不下降。电磁阀有故障，给予信号也不动作。逐步检查，发现SQ4未发出信号。进一步对SQ4进行检查，发现感应间隙过大，导致接近开关无信号输出，产生动作障碍。将感应间隙δ调至故障消除。换刀臂平移至C位置时.3根据控制对象的工作原理诊断故障。根据PLC的梯形图来分析和诊断故障是解决数控机床故障的基本方法。用这种方法诊断机床故障，首先应搞清机床的工作原理，动作顺序和联锁关系，然后利用系统的自诊断功能或通过机外编程器，根据PLC梯形图查看相关的输入输出及标志位的状态，从而确定故障原因。

13，故障报警代码：F2074故障描述：电机当前位置超出绝对编码器窗口，断电时的位置与重新上电后的位置偏差太大，超过了窗口 值 P。对策：复位重启或者重新建立位置参考点。
14，故障报警代码：F2048。，四，电动机空载电流不平衡，三相相差大.故障原因绕组首尾端接错，电源电压不平衡，绕组存在匝间短路，线圈反接等故障。.故障处理检查并纠正，测量电源电压，设法消除不平衡，消除绕组故障。五，电动机运行时响声不正常，有异响.故障原因轴承磨损或油内有砂粒等异物，转子铁芯松动，轴承缺油，电源电压过高或不平衡。.故障处理更换轴承或清洗轴承，检修转子铁芯，加油，检查并调整电源电压
电机马达维修_技术支持,例4：配备SIN810数控系统的加工中心，出现分度工作台不分度的故障且无报警。根据工作原理，分度的齿条和齿轮啮合，这个动作是靠液压装置来完成的，由PLC输出Q1.4控制电磁阀YVl4来执行。
