既然要看大全，那就要看全面，而不是抓一部分出来钻牛角尖。6Se70分为AC-AC和DC-AC两种型号，你说的x1.34估计是指Ac-AC部分的。

P071 Line Volts

Function parameter for entering the line voltage of the converter or inverter.

Converter (AC/AC): rms value of the line AC voltage

Inverter (DC/AC): input direct voltage

The value is for calculating the rated DC link voltage as a basis for the voltage limits of the Vd(max) and Vd(min) [KIB) controller

(e.g. undervoltage failure limit).
