Infeed modules

The infeed modules are used to connect the drive group to the line supply.
The infeed modules generate the DC voltage for the DC link from the following
possible line supply voltages:
S
3–ph. 400 V AC $10% 50 Hz/60 Hz,
S
3–ph. 415 V AC $10% 50/60 Hz,
S
3–ph. 480 V AC + 6% –10% 50 Hz/60 Hz
In addition, the electronic voltages ($24 V, $15 V +5 V, etc.) are made avail-
able centrally to the drive modules and to the SINUMERIK 840D or SINUMERIK
810D – arranged as group – via the equipment bus.
A transformer with separate windings in vector group yn in accordance with the
selection table 7-6 is required if the infeed modules are connected to a line sup-
ply that is different from a TN line supply or a line supply not equipped with di-
rect–current–sensitive residual–current devices.
The HF commutating reactor is also required for the regulated infeed/regenera-
tive feedback module when there are upstream transformers.
An appropriate matching transformer is also required for line supply voltages of
3–ph. 200 V/220 V/240 V/440 V/500 V/575 V AC 10% 50 Hz/60 Hz.
Please observe the appropriate information and instructions for the 300 mm
modules.
For the arrangement of the infeed module, see Chapter 2.1.1.
A minimum lateral clearance of 50 mm must be maintained between the module
groups mounted at the same height.
The required cooling components, such as separate fan and/or air baffle plates
to guide the cooling air to the module heatsinks, are included in the standard
packages for modules with a width of up to 200 mm for both the internally and
externally cooled versions.
S
Internal cooling
The infeed modules can be ordered with module–internal heatsinks for cool-
ing inside the control cabinet. The 300 mm wide modules also provide the
option of connecting a hose for use as a targeted air guide.
S
External cooling
Alternatively, the infeed modules are available with a heatsink that extends
outside the module for external heat dissipation. In this case, the modules
are mounted on the rear cabinet panel with the heatsink extending through
the panel. Heat dissipation is provided by the customer. For this type of con-
figuration, a mounting frame is required for each module (refer to Fig. 2-9).
