3AFE61101853Hardware Description 1 Introduction with DCV 700 DC drive
The DCV 700 series is a complete range of DC converters intended for
the supply and control of separately excited DC machines in stand-alone
or multi-drive systems. DCV 700 offer a complete enclosed version
including application-, drive- and torque control.
