EtherCAT igh主站控制3个台达asdaa2伺服转圈圈_台达伺服烧写xml

1.查看ASDA的PDO映射

打开ASDA的Delta_ASDA2-E_rev4-00_XML_TSE_20160620.xml文件

修改main.c的pdo部分

2.使能伺服

设置0x6060和0x60C2

    for(int i=0;i<3;i++)
    {
        ecrt_slave_config_sdo8(sc_asda[i], 0x6060, 0, 8);//设置为csp模式
        ecrt_slave_config_sdo8(sc_asda[i], 0x60C2, 1, 1);//设置插补周期为1ms
    }

设置伺服DC，我写了篇文章有谈到这个函数EtherCAT igh源码的ecrt_slave_config_dc（）函数的理解。
https://blog.csdn.net/cln512/article/details/103365240

    ecrt_slave_config_dc(sc_asda[0], 0x0300, 1000000, 0, 0, 0);
    ecrt_slave_config_dc(sc_asda[1], 0x0300, 1000000, 0, 0, 0);
    ecrt_slave_config_dc(sc_asda[2], 0x0300, 1000000, 0, 0, 0);

将【Controlword:6040h】依序设定为 (0x06 > 0x07 > 0x0F)，使驱动器 Servo On 并让电机开始运作。

                switch (ecstate){
                case 1:
                    EC_WRITE_U16(domainOutput_pd + cntlwd[i], 0x80);       
                    break;
                case 7:
                    curpos = EC_READ_S32(domainInput_pd + actpos[i]);       
                    EC_WRITE_S32(domainOutput_pd + ipData[i], EC_READ_S32(domainInput_pd + actpos[i])); 
                    printf("x@rtITP >>> Axis %d current position = %d\n", i, curpos);
                    break;
                case 9:
                    EC_WRITE_U16(domainOutput_pd + cntlwd[i], 0x06);
                    break;
                case 11:
                    EC_WRITE_U16(domainOutput_pd + cntlwd[i], 0x07);
                    break;
                case 13:
                    EC_WRITE_U16(domainOutput_pd + cntlwd[i], 0xF);
                    break;
