SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
2.4.3
Drive module
The drive modules comprise the following components: Power module, control
unit, equipment bus cable and where relevant, a drive bus cable and option
module.
The permissible combinations of power module and control unit are saved in the
engineering tables (refer to Chapter C.1.1). Depending on the cooling method
employed or the power module’s size, additional cooling components have to
be ordered or be provided by the user.
Depending on the application, the drive modules of the SIMODRIVE 611 con-
verter system can function as feed, main spindle or induction motors, and com-
prise the power module, control unit, and drive bus cable components. Option
modules can be added where applicable.
A drive module is created by inserting the control unit into the power module,
e.g. for feed or main spindle applications.
The modular design of the drive modules allows a large number of applications
to be implemented using only a small number of individual components.
Note
Combinations that differ from the engineering information and instructions –
where relevant, also in conjunction with third–party products, require a special,
contractual agreement.
We accept a warranty for our scope of supply up to the system interfaces that
we have defined.

Power modules
A wide range of 1–axis or 2–axis power modules is available. These modules
are graded according to the current ratings and can be supplied with three dif-
ferent cooling techniques. The range of power modules allows a seamless,
modular and space–saving drive solution for:
S
Small, compact machines (required feed torques and main spindle power
ratings – e.g. 80 Nm at 500 RPM and 11 kW S1 at 1500 RPM) up to
S
complex machining centers and automatic lathes – e.g. 115 Nm or 145 Nm
at 2000 RPM and 100 kW S1 at 1500 RPM.
The current–related data refers to the series–preset values. The output currents
can be limited by the control unit being used. After the control unit has been
inserted, the retaining screws of the control unit front panel must be tightened in
order to establish a good electrical connection to the module housing.
At higher clock cycle frequencies, ambient temperatures and installation alti-
tudes above 1000 m above sea level, the modules must be derated. The ap-
propriate pre–assembled cables are available to connect–up the motors. The
ordering data is provided in Catalog NC 60, in the Motors Section.
Shield terminal plates are available to meet EMC requirements when using
shielded power cables.
The equipment bus cable is included in the scope of supply of the power mod-
ule. The drive bus cables must be ordered separately for the digital system.
