求翻译：摆频运行时，变频器的输出频率以设定频率为中心进行上下摆动，其中摆频幅度由P0-180设定，当P0-180设定为0时，摆频运行无效。是什么意思？

Pendulum frequency operation, the frequency of the inverter output frequency to set the center up and down swing, the pendulum frequency amplitude set by p0 is-180-180 p0 is set for 0:00, the traverse run is invalid.

When suspends the frequency movement about, the frequency changer output frequency take establishes the frequency to carry on as the center swings, in which suspends the frequency scope by the P0-180 hypothesis, when the P0-180 hypothesis is 0, suspends the frequency movement to be invalid.

Swing frequency running, inverter output frequency setting frequency to the Center up and down, swing set from P0-180, when P0-180 is set to 0 o'clock, and running frequency is not valid.
