Configuring SIP planetary geared motors and SIP planetary gear units
Configuring sequence – overview

■
Overview
General configuring information is provided for the standard
version in this catalog.
SIP planetary gear units/geared motors permit individual solu-
tions to be created for a wide range of drive applications. In
order to select the correct drive, specific data for the application
must be known or determined in advance.
For drives operating under special conditions, e.g. frequent re-
versing, short-time or intermittent duty, abnormal temperatures,
reversal braking, extreme cantilever forces at the gear unit out-
put shaft, etc. please contact your Siemens contact person with
all technical questions.
Installation in potentially explosive areas (ATEX)
SIP planetary gear units designed for operation in potentially
explosive areas are available. The explosion-proof versions
conform to Directive 94/9/EC. The drive motor must be selected
separately and must satisfy the same environmental conditions
as the SIP planetary gear unit.

Configuring
There are basically two methods of configuring a drive system:
1. Start the process on the basis of the required operational
torque and the driven machine speed for the customer's
process.
2. Start the process on the basis of a specified power output and
the speed for the customer's process.
The configuring sequence for both methods is described on the
following pages, in one case for planetary geared motors and, in
the other, for planetary gear units without a motor.
The flow chart below illustrates how to select the appropriate
configuring sequence:
When the process is started by specifying a power output, there
is a risk that
P
N
(motor nominal power) will be mistakenly inter-
preted as
P
2
. This could result in an overdimensioned gear unit.
Siemens therefore recommends that
P
2
or
T
2
(drive operating
point) should be used as the starting point for the design
process.
