基于Clipper数控伺服系统的限位与回零研究

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 combina-tion of homing switch and the index channel as a double-trigger homing condition. Sending online instruc-tions、writing motion program or PLC program in the slave computer software window for motor move, ob-serve 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 accord-ing to the limit and home mode, which provides the basis for high precision position control.
