Arrangement of the modules

The infeed module should always
be located to the left
of the module group.
1)
Drive bus cable
Equipment bus cable
The shield connecting plates
are necessary to ensure that
the wiring meets EMC
requirements.
1) Note:
A round drive bus cable fed from the module group (6SX2002–xxxx) should preferably
be attached to the 6SN1162–0FA00–0AAx shield connection or clamped to the
provided insert nut on the module housing!

The modules must be arranged in a particular layout. The following criteria must
be taken into account:
S
Function of the module
S
Cross–section of the DC link busbar
The I/R or UI module is always located to the left of the module group at the
beginning. The power modules (PM) are located to the right next to the I/R or UI
modules (refer to Fig. 2-1).
For the NC control system
Due to the limited conductivity of the DC link busbars of the modules with mod-
ule width p150 mm, the DC link power P
55 kW. Larger DC link busbars must be used if this restriction cannot be com-
plied with (refer to Fig. 2-2 and 2-3).
The DC link power P of the subsequent modules is calculated according to
ZK
the engineering rule specified in Chapter 1.3.
The larger DC link busbars can be ordered as a set with
Order No. [MLFB] 6SN1161–1AA02–6AA0. The set includes reinforced DC link
busbars for module widths 50 mm, 100 mm and 150 mm.
The standard DC link brackets between the modules may not be changed, even
when strengthened DC link busbars are used.
SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
The largest power module must be located after
the infeed module; all of the other power
modules are then located to the right
corresponding to their size (power rating).
The capacitor modules
must be located at the
end of the drive line–up
after the power
modules.
of these modules must not exceed
