The control system of the compressor adopts frequency conversion to control, its frequency setting value is decided by the non-linear link.
压缩机控制系统采用变频控制，其频率给定值由非线性环节来决定。
This setting can be set to a value between 1 and 1000 which will result in a 0.1 percent to 100 percent reduction in frequency.
这个设置可以设置为1到1000之间的值，这会使频率下降百分之0.1到百分之百。
