DC connection
The UDC+ and UDC– terminals are intended for common DC configurations of a
number of ACSM1 drives, allowing regenerative energy from one drive to be utilised
by the other drives in motoring mode.
One or more drives are connected to the AC supply depending on the power
requirement. In case two or more drives are connected to the AC supply, each AC
connection must be equipped with a mains choke to ensure even current distribution
between the rectifiers. The diagram below shows two configuration examples.
