伺服驱动器是用来控制伺服电机的一种控制器,其作用类似于变频器作用于普通交流马达,属于伺服系统的一部分,主要应用于高精度的定位系统。一般是通过位置、速度和力矩三种方式对伺服马达进行控制,实现高精度的传动系统定位,目前是传动技术的高端产品。
相关区别
1、伺服控制器通过自动化接口可很方便地进行操作模块和现场总线模块的转换,同时使用不同的现场总线模块实现不同的控制模式(RS232、RS485、光纤、InterBus、ProfiBus),而通用变频器的控制方式比较单一。
2、伺服控制器直接连接旋转变压器或编码器,构成速度、位移控制闭环。而通用变频器只能组成开环控制系统。
3、伺服控制器的各项控制指标(如稳态精度和动态性能等)优于通用变频器。
伺服控制器的基本要求
伺服进给系统的要求
1、调速范围宽
2、定位精度高
3、有足够的传动刚性和高的速度稳定性
4、快速响应,无超调
为了保证生产率和加工质量,除了要求有较高的定位精度外,还要求有良好的快速响应特性,即要求跟踪指令信号的响应要快,因为数控系统在启动、制动时,要求加、减加速度足够大,缩短进给系统的过渡过程时间,减小轮廓过渡误差。
5、低速大转矩,过载能力强
一般来说,伺服驱动器具有数分钟甚至半小时内1.5倍以上的过载能力,在短时间内可以过载4~6倍而不损坏。
6、可靠性高
要求数控机床的进给驱动系统可靠性高、工作稳定性好,具有较强的温度、湿度、振动等环境适应能力和很强的抗干扰的能力。
