目前实际情况是输出没有电抗 直接接到负载 电缆长度超过5米
-----> 按照SINAMICS S120工程手册上的规则, 输出侧可以不考虑平衡电抗器!

引用原文如下:
In the case of motors with a common winding system, the minimum cable lengths
between Motor Module and motor stated below must be observed for the purpose
of decoupling the parallel-connected Motor Modules. The specified output powers
refer in each case to one of the Motor Modules of the parallel connection. If it is
not possible to realize cabling with the minimum required cable length, motor
reactors or filters must be installed.
