Infeed modules
The drive group is connected to the power supply via the infeed modules. The
infeed modules generate the DC voltage for the DC link from the line supply
voltage 3–ph. 400 V AC $10%
50 Hz / 60 Hz, 3–ph. 415 V AC $10 % 50 Hz / 60 Hz, 3–ph. 480 V AC + 6%
–10%
50 Hz / 60 Hz. In addition, the electronic voltages ( $24 V, $15 V +5 V etc.) are
provided centrally to the drive modules, or the SINUMERIK 840D or SINUME-
RIK 810D, in the drive group, via the equipment bus. A transformer with sepa-
rate windings in vector group Yyn0, according to the selection table, is required
if the infeed modules are connected to a line supply other than TN line supply or
to a line supply which is not equipped with DC sensitive residual–current–opera-
ted protective devices. An HF commutating reactor is also required for series
transformers for the controlled infeed/regenerative feedback module.
In addition, an appropriate transformer must be selected to adapt the voltage for
line supply voltages 3–ph. 200 V / 220 V / 240 V / 440 V / 500 V / 575 V AC
10%
50 Hz / 60 Hz.
The necessary cooling components, such as separately–driven fan and/or air
guides to guide the air at the module heatsinks are, for modules up to 200 mm
wide, included in the scope of supply, both for the internally as well as externally
cooled versions.
The appropriate instructions must be observed for the 300 mm modules.
The infeed module must always be located as the first module to the left. This is
then followed, if used, by the NCU box. This is then followed by the main
spindle drive modules (induction motor drive modules) and the feed drive modu-
les which should then be located, with decreasing rated currents from left to
right at the infeed module.
A minimum clearance of 50 mm to the side must be maintained between mo-
dule groups mounted at the same height.
SIMODRIVE 611 modules can be supplied with an internal heatsink for heat
dissipation (cooling) within the cabinet; 300 mm–wide modules also have the
possibility of connecting a hose for hose cooling. All of the module widths are in
a 50 mm grid and all of the modules are 480 mm high. However, it should be
noted that the dimensions for the air guide and shield connection plate, moun-
ted fans and hose cooling must be additionally taken into account. Alternatively,
modules are also available with a heatsink which extends outside the module
so that heat is dissipated externally. In this case, the modules are mounted on
the rear side of the cabinet through which the heatsink extends; cooling is reali-
zed on the customers side. With this configuration, a mounting frame is required
for every module (refer to Fig. 2-7). For internal cooling or hose cooling, all of
the modules are 288 mm deep (without connector and mounted options) refer-
red to the mounting plane; all externally cooled modules are 231 mm deep. The
protrusion depth of the heatsink must be taken into account for the cooling duct.
