【英为有你】GD350走开环模式，高速脉冲输出同步的调试方法
<p><span style="font-family: arial, helvetica, sans-serif;">1、将p00.18设为1恢复出厂设置，然后根据电机铭牌设置电机参数，设置P00.15=2进行静态自学习；</span></p><p><span style="font-family: arial, helvetica, sans-serif;">2、根据现场的机械传动比轴径等信息计算出线速度同步时主从机的频率比，</span></p><p><span style="font-family: arial, helvetica, sans-serif;"><strong><span style="font-family: 宋体; font-weight: bold; font-size: 14px;"><span style="font-family: 宋体;">线速度</span><span style="font-family: Times New Roman;">=</span><span style="font-family: 宋体;">最大频率</span><span style="font-family: Times New Roman;">/</span><span style="font-family: 宋体;">额定频率</span><span style="font-family: Times New Roman;">*</span><span style="font-family: 宋体;">额定</span></span></strong><strong><span style="font-family: 宋体; font-weight: bold; font-size: 14px;"><span style="font-family: 宋体;">转速</span><span style="font-family: Times New Roman;">*</span><span style="font-family: 宋体;">Π</span><span style="font-family: Times New Roman;">*</span><span style="font-family: 宋体;">轴径</span><span style="font-family: Times New Roman;">*</span><span style="font-family: 宋体;">齿轮比， </span></span></strong><span style="font-weight: bold; font-size: 14px; font-family: 宋体;"></span><strong><span style="font-weight: bold; font-size: 14px; font-family: 宋体;"><br/></span></strong></span></p><p><span style="font-family: arial, helvetica, sans-serif;">然后根据比率设置变频器的最大频率值，</span></p><p><span style="font-family: arial, helvetica, sans-serif;">3、<span style="font-family: 宋体; font-size: 14px;"><span style="font-family: 宋体;">然后设置主要参数</span><span style="font-family: Times New Roman;">P00.00</span><span style="font-family: 宋体;">为</span><span style="font-family: Times New Roman;">0</span><span style="font-family: 宋体;">开环矢量</span><span style="font-family: Times New Roman;">0</span><span style="font-family: 宋体;">，</span><span style="font-family: Times New Roman;">P00.03</span><span style="font-family: 宋体;">主机为</span><span style="font-family: Times New Roman;">50</span><span style="font-family: 宋体;">，从机为</span><span style="font-family: Times New Roman;">60</span><span style="font-family: 宋体;">，</span><span style="font-family: Times New Roman;">P00.06</span><span style="font-family: 宋体;">主机</span><span style="font-family: Times New Roman;">8 modbus</span><span style="font-family: 宋体;">给定，从机</span><span style="font-family: Times New Roman;">4</span><span style="font-family: 宋体;">高速脉冲输入，</span><span style="font-family: Times New Roman;">P00.11</span><span style="font-family: 宋体;">加减速主机为</span><span style="font-family: Times New Roman;">6</span><span style="font-family: 宋体;">，从机为</span><span style="font-family: Times New Roman;">0</span><span style="font-family: 宋体;">，跟随主机启动，然后主机</span><span style="font-family: Times New Roman;">P6</span><span style="font-family: 宋体;">组在设置高速脉冲输出对应</span><span style="font-family: Times New Roman;">1~21KHz</span><span style="font-family: 宋体;">，从机</span><span style="font-family: Times New Roman;">P5</span><span style="font-family: 宋体;">组高速脉冲输入设置也为</span><span style="font-family: Times New Roman;">1~21KHz</span><span style="font-family: 宋体;">就可以正常上电运行，</span></span></span></p><p><span style="font-size: 14px; font-family: arial, helvetica, sans-serif;">4、运行高速，用测速仪测量主从轴的速度是否一致，然后速度依次降低测量，如果数值差别较大，则需要调整最大频率<br/></span></p><p><span style="font-family: arial, helvetica, sans-serif;">5、<span style="font-family: 宋体; font-size: 14px;"><span style="font-family: 宋体;">如果低速出现并不同步，高速同步则微调</span><span style="font-family: Times New Roman;">P6.27</span><span style="font-family: 宋体;">高速脉冲输出下限百分比，若低速同步高速不同步则调整</span><span style="font-family: Times New Roman;">p6.29</span><span style="font-family: 宋体;">上限百分比，调整幅度尽量小</span></span></span></p>
