【摘要】：对基于Clipper数控伺服系统的构成和控制方式进行阐述,采用速度模式连接,进行全闭环控制。并对限位和回零进行研究,提出软限位与硬限位结合的双重限位方式,回零开关和索引通道的逻辑组合作为双触发回零条件。在下位机软件窗口发送在线指令、编写运动程序或PLC程序进行移动,观察电机状态位判断各轴限位和回零功能是否完成,采集回零搜索的实时数据检验回零轨迹。系统根据该限位和回零方式,实现了超程保护和精确回零,为高精度位置控制提供了基础。
[Abstract]:The structure and control mode of CNC servo system based on Clipper are described. The speed mode is used to control the whole closed loop. The double limit mode of soft limit and hard limit is put forward. The logic combination of zero return switch and index channel is used as double trigger zero back condition. The on-line instruction is sent in the software window of the lower computer, the motion program or PLC program is written to move, the motor state position is observed to judge whether the function of limiting and returning zero is completed or not, and the real time data of zero back search is collected to check the trace of return zero. According to the method of limit and return, the system realizes over-range protection and accurate return to zero, which provides the foundation for high precision position control.
