令牌总线通讯方式令牌总线通讯方式又称为N：N通讯方式是指在总线结构的PLC子网上有N个站，它们地位同等没有主站与从站之分，也可以说N个站都是主站。N：N通讯方式采用令牌总线存取控制技术。在物理总线上组成一个逻辑环，让一个令牌在逻辑环中按一定方向依次活动，获得令牌的站就取得了总线使用权。令牌总线存取控制方式限定每个站的令牌持有时间，保证在令牌循环一周时每个站都有机会获得总线使用权，并提供优先级服务，因此令牌总线存取控制方式具有较好的实时性。

CCW/CW：驱动禁止信号，一般和行程开关配合使用，避免超程，该信号可由参数PA20设置。PA20=0：使用驱动禁止功能；PA20=1：不使用驱动进制功能。RDY：驱动单元准备好信号，当电机通电励磁时该信号有输出。位置指令输入信号这里位置输入信号可以采用差分驱动或者单端驱动接法，由于选用的FBS-24MCT为集电极开路输出形式，所以采用单端驱动接法。伺服驱动单端驱动方式限定外部电源最大电压为25V时，需要串接一个限流电阻R依据：Vcc=24V，R=1.3KΩ~2KΩ；Vcc=12V，R=510KΩ~820KΩ；Vcc=5V，R=0；频率限制为：PLS/DIR：最高脉冲频率500KHZU/D：最高脉冲频率500KHZA/B：最高脉冲频率300KHZ控制线制作GSK随机附带一个44针插座，依据引脚图，把需要的控制信号接线出来。
