平凡的脚步也可以走完伟大的行程。
PLC输人线路与动力线路不能位于同一线槽或电线管内,三相动力线路束在一起走线,并且使两部分尽可能相互垂直走线,输人线也可采用屏蔽线,以防动力线路干扰输入线路。
采用PLC对专用镗床进行电气控制是一种行之有效的技术进步手段实践证明,它降低了专用镗床电控系统的故障率,大大提高了其工作的可靠性,改善了其控制性能,提高了机床的加工精度,与此同时,在一定程度上降低了设备能耗。在实际使用中,效果良好。
PLC(可编程序控制器)是专为工业现场使用的计算机,由于其处理开关量大,多达上千个,且不改变外部接线,只改变程序就可以完成控制系统的修改。省时、省力、编程容易、操作简单,同时PLC具有体积小,功耗低,性价比高。可靠性高,抗干扰能力强,故障率低。维护简单,自动化、集成化程度高,能够完成较复杂的逻辑运算。
