DC voltage detection gain: L-00
This parameter indicates detection adjustment gain of DC voltage detected by the converter.
By inputting the voltage between the DC terminals [+] and [-] during converter initialization, this DC voltage
detection gain is back calculated and the resulted value is set to this parameter. Normally, use it without
changing the initialized value.
When the gate board <GAC66>, etc. is replaced, an error may occur between "Vdc" display on the console and the
actual voltage between the DC terminals [+] and [-]. In this case, to adjust DC voltage detection gain without
initializing memory, refer to {5.4.3. DC Voltage Detection Gain Adjustment}.
Also, when the control board <VFC66R-Z> is replaced, refer to {5.4.3. DC Voltage Detection Gain Adjustment}
and perform adjustment.

Analog output selection: L-01 and L-02
With these parameters, select the analog output between the analog output (2) terminal [AOT2]/analog output
(3) terminal [AOT3] and the terminal [G-OT]. Install an optional board to use the analog output.
