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.
If the infeed modules are connected to a line supply other than a TN line supply,
or a line supply that is not equipped with suitable residual current protective
devices, then an additional transformer with separate windings in vector group
yn is required according to selection table 7-8.
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 necessary cooling components, such as externally mounted fan and/or air
baffle plates for a module width of 100 mm to guide the air at the module heat
sinks must be separately ordered when required. For other module widths, the
baffle plates should be appropriately produced according to the drawing, see
the dimension drawing in Chapter 12.
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, that can be or-
dered for pipe cooling, also offer the option of connecting a pipe for direct air
cooling.
S
External cooling
Alternatively, infeed modules with heat sinks outside the housing for external
cooling are available. When mounting, the heatsinks are inserted through
the openings at the rear of the cabinet. Cooling is then realized on the cus-
tomer side. For this type of configuration, a mounting frame is required for
each module (refer to Fig. 2-9).
