</span></span>接口的变频器进行连接，实现数据通讯和控制任务。</div><div class="t m0 x1 h2 y5 ff2 fs0 fc0 sc0 ls0 ws0">一、通讯基础</div><div class="t m0 x1 h2 y6 ff2 fs0 fc0 sc0 ls0 ws0">台达<span class="_ _0"> </span><span

class="ff2">发送启动命令给变频器，<span class="_ _7"></span>变频器接收到命令后开始工作，<span class="_ _7"></span>驱动电机运转。<span class="_ _7"></span>同样地，</span></span></div><div class="t m0 x1 h2 y14 ff2 fs0 fc0 sc0 ls0 ws0">当需要停止电机时，<span class="_ _4"></span><span class="ff1">PLC<span class="_ _0"> </span><span class="ff2">发送停止命令给变频器，<span class="_ _4"></span>变频器则根据命令停止工作，<span class="_
