In documentation "project planning" ctrlX DRIVE we find XG31 connector as onboard interface on XVR1 device. Usually for control sections XG31 stands for digital and analog I/O. What is the function of XG31 in case of power supply XVR1? No further details are described in the documentation.
XG31 on XVR is for signals LB ("ready for power") and Bb ("ready to run"). See Fig. 4-77 on page 150/431 of manual DOK-XDRV**-X**********-PR06-EN-P (R911386579)
If not controlling the power supply devices by fieldbus the digital I/Os are necessary to do so. A detailed How-to to this topic will be soon published in the dedicated area.
