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。
Structure and control mode of the CNC Servo System based on Clipper was expounded,the fully closed-loop control is carried out by using the speed mode connection. Have a research on the limit and home,the soft limit and hard limit combination of the doubl-limit mode was proposed,the logical combination of homing switch and the index channel as a double-trigger homing condition. Sending online instructions、writing motion program or PLC program in the slave computer software windowfor motor move,observe the motor status bit to determine the axis limit and homing function was completed,collecting homing search real-time data test homing trajectory. The system has overrun protection and accurate homing according to the limit and home mode,which provides the basis for high precision position control.
