Detailed Explanation of Each Parameter
5.3.1.
Basic Setting Area
In the basic setting area, the commonly used basic setting items to operate the converter are summarized.
Settings such as DC voltage command and power-factor angle via the console are performed in this area.
Before operating the converter, be sure to set each parameter according to the power supply specification.
Of the units shown in the table, only "Hz," "A," "V" and "kW" can be displayed on the standard console. Other
units cannot be displayed.

DC voltage setting: 0.VrEF
Set the DC voltage command for the case that the DC voltage command fixed mode selection: <d-00> is set to ON.
With the DC voltage command fixed mode selection: <d-00> set to OFF, the DC voltage command variation mode is
entered and thus this setting is ignored.
For the DC voltage command variation mode, refer to the description of setting items in the area d in this manual.
Setting with the console can be done in increments of 0.1 V for the 400 V class unit. However, the setting is
reflected in increments of 0.2 V internally. Keep this in mind.
* Caution
A DC voltage cannot be made lower than a value obtained by "effective value of AC line voltage x 1.56 (V)."
When a value obtained by "effective value of AC line voltage x 1.56 (V)" becomes higher than the setting of
"0.VrEF," a DC voltage command becomes a value obtained by "effective value of AC line voltage x 1.56 (V)."
Note that the maximum DC voltage command is 358 V (200 V class)/716 V (400 V class).
