DC power cable connection diagram (optional)
The UDC+ and UDC- terminals are intended for common DC configurations of a
number of MicroFlex e190 drives.
AC supply (DC sharing)
DC sharing allows regenerative energy from one drive to be utilized by other drives
that are in motoring mode. Each drive is connected to the AC supply* and has its own
brake resistor. The MicroFlex e190 drives’ DC connections are linked as shown in the
diagram below.
