54 Electrical installation: AC input / DC input, motor and brake
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 on
e 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 li
nked as shown in the
diagram below.

DC supply
MicroFlex e190 can use a DC supply as the primary power source (see page 154).
Each drive is powered from the DC supply a
nd has its own brake resistor. There is no
AC supply.
