When the output circuit between the frequency converter and the motor is too long, it will have the following effects:

1．线路压降增大；

1. The line voltage drop increases;

2.线路漏电流增大；

2. The line leakage current increases;

3.长线分布电容和电感方面会产生很高的dv/dt,易损坏电机。

3. High DV / dt will be produced in long line distributed capacitance and inductance, which is easy to damage the motor.

解决方法

Resolution:

1、适配交流输出电抗器；

1. Adapt to AC output reactor;

2、变频器功率放大一档使用。

2. The frequency converter is used in the first gear of power amplification
