步骤如下： 1．将控制输出禁止输出到端口 MD30130 CTRLOUT_TYPE =0 2．将位置和速度反馈设为模拟反馈和无编码器 MD30200 NUM_ENCS=0 MD30240 ENC_TYPE =0 3．驱动配置中，屏蔽控制模块 到驱动配置画面中，将相应的轴控制激活状态改为“NO” 图2 - 3 驱动模块n o t A c t i v e 图2 - 3 驱动模块n o t A c t i v e ------------------------------------------------------------------------------------------------------------------------------------------ BeiJing CAPE Precision Mechanical’4?:)?$0?m7H?*5 ------------------------------------------------------------------------------------------------------------------------------------------ BeiJing CAPE Precision Mechanical?9.13? ???q????????i¯??fi *5 6?9F?0$1) ????›??i¯??fi *5 ,$):5?????*5 +?$@F9)*?????*5 +/$:??:£???z{kl]?*5 +74A*F ?)5??7??48 ??????]^_‘ ??.?/,???2? +0:1F:5??????*5 /*??? 13 ?W*5 75:?? 13 ?W*5 85?F)0?5? ?I*5 -*?*: ?? *: ?W*5 ?5?F)0?/?? 5? ?I*5 /,??????????????*5 7#?.?+/??d ??9???????HIe? 7#??.?/--?d ?????????????HIe? ??? ?? ------------------------------------------------------------------------------------------------------------------------------------------ BeiJing CAPE Precision MechanicalAŁØ??@?+13 ??]?*5 7+?.?#+$??)?+????R????? + ? 7+ ]?2?*5 #/?.???HI?CD ?+?.??8????›?*5 ?-?.??#9 ?#Z*5 ????›??¡? ?6?.?6????2? 6+?.?6,??Ł?6 )???9????“ 9????????????
