4軸電壓型步進/伺服電機移動控制卡 主要特點 2/3軸圓弧插補功能 PCI總線接口 可編程T/S曲線加速/減速 異步/同步4軸移動控制 慢進功能 線性/螺旋插補功能 連續(xù)插補功能 內(nèi)容介紹 PCI-1242 applied motion ASIC sends the pulse of each axis with DDA （Digital Differential Analyzer） algorithm to realize 4 axis servo positioning and synchronized control. Under the pulse output control, the encoder value can be read back from the encoder input port. So, it will be easier to carry out the software close loop control in stepping motor application. At the control of each axis, there is one set of sensor input point, including home point, plus limit point and minus limit point. In addition, there are inhibit signal output points, position ready output point, and emergency stop input point. For other input / output points, this board uses wiring saving IO design, which can be expanded to 64 points input and 64 point output maximum.
