为什么选用CANopen?

可支持多轴

CANopen最多支持控制127个轴,且通讯速率可高达1Mbps。

CANopen总线对数据通信数据块进行编码的方式,可以多主方式(Multi-master, 采用可靠的错误处理和检错机制,其协议包含了系统的,专业的工业用设备子协议,是专门为工业控制而发展的总线协议。符合工业控制所要求的高速,稳定可靠,高实时性要求

布线简单

用传统脉冲方向或模拟量来驱动一个直角坐标机构至少需要连接4根线或者更多,CANopen方案布线简单,所有轴并联接入CAN_H和CAN_L信号即可。减少布线,更少出错,减少布线成本,人工成本,后期电缆老化或故障的维护成本,以及由于复杂的线路故障带来的不可估量的损失。


如下一些参考例程,供参考
