Supply Infeed (NE)
The infeed/regenerative feedback module (I/R module) and the module for the
uncontrolled infeed (UE module), is used to feed the DC link. Beyond this, the
I/R–, UE–, and the monitoring module (monitoring module) also provide the
electronics power supply for the connected modules.
For the I/R module, when braking, the kinetic energy of the drives, fed back into
the DC link, is fed back into the line supply.
For the UE module, when braking, the drive kinetic energy, fed back into the DC
link, is converted into heat in the brake resistors which are either integrated or
mounted. This heat is then dissipated to the environment. When required, addi-
tional single or several pulsed resistor modules can be used within the configu-
ring limits (pulsed resistor modules) (a pulsed resistor is not integrated in all of
the modules).
The I/R–, UE module is located as the first module to the left in the drive group.
The monitoring module is located in the drive group, to the left of the modules to
be supplied.
To fulfill the CE conformance for the radio interference voltage limit values, filter
modules, line filters and screen cables are available.
