楼上的大侠太谦虚.大家知道95%以上的应用采用电机上的编码器信号,就可获得满意的控制精度.您是指负载与电机位置之间的偏差吧?例如通过滚珠丝杠方式把电机与负载联上.如是这种情况而且您的位置精度要求特高,您就可在负载所在位置加另外一个编码器.Triomotion有专门的指令来实现全闭环控制.
指令可简化为: ADD_DAC(Axis)
The ADD_DAC command is provided to allow a secondary encoder to be used on a servo axis to implement dual feedback control. This would typically be used in applications such as a roll-feed where you need a secondary encoder to compensate for slippage. The ADD_DAC function allows the output of 2 servo loops to be summed on to the speed demand output to a drive.
如果我理解错了您的原意,请指教,谢谢!
