General information
All information and instructions contained in
instruction manuals or any other instructions
supplied must be observed.
This is indispensable for the avoidance of risk and damage!
An additional safety information sheet is enclosed (yellow) which
provides supplementary information on the safety of electrical
machinery and equipment. These safety instructions are therefore
also intended to supplement all other instruction manuals or any
other instructions supplied.
Furthermore, the applicable national, local and plant-specific
requirements and regulations must be observed!
The technical specifications of special versions and design
variations may differ from those specified! If you have any doubts
whatsoever, we strongly advise that you consult the manufacturer,
giving details of type designation and serial number, or that you have
the service work carried out by a SIEMENS Service Center.

1 Description
1.1 Range of applications
The 1FT5 motors are designed in particular to be used as drive units for
machine tools, robots, loading equipment and the like. They can be
installed in roofed-over areas with normal climatic conditions. The motors
are designed for ambient temperatures of -10°C to +40°C.
1.2 Mode of operation and construction
The 1FT5 motors are permanent-field three-phase AC synchronous
motors for operation with motor-controlled pulse-width-modulation inverters
according to the block current principle. They are characterised by good
dynamics and a wide speed range.
There is a temperature sensor incorporated in the three-phase motor
stator winding which acts as a motor protector.
The tachogenerator and rotor position encoder integrated in the
standard version serve as a means of identifying the speed and position
of the rotor.
Additional fittings and attachments (to order) included
- Encoder systems such as incremental encoders (e.g.
..), absolute value encoder, etc.
- Fail-safe brake;
NOTE: In principle it is possible to replace or retrofit a fail-safe holding
brake; however, the modification should only be done by a SIEMENS
Service Center.
2 Operation
2.1 Transportation, storage
If a motor is not put into service immediately on receipt, it should be stored
in a dry and dust-free room where it will not be subjected to shocks.
2.2 Installation
Take note of the information regarding type of construction and degree of
protection given on the rating plate and check that these specifications
match the site conditions!
NOTE: In the case of machines where the shaft end points upwards, it is
imperative to ensure that no liquid (water, machining coolant, etc.) can run
into the top bearing.
Never strike or exert pressure on the end of the shaft when installing the
motor!
The motor must be fitted in such a way that heat loss can be adequately
dissipated.
The surfaces of the motors can reach high temperatures of over
100°C. No temperature-sensitive items such
as normal wires or electronic components
should be touching or attached to these
surfaces. If necessary, take precautions to prevent contact!
The system vibration behaviour on site caused by drive elements,
mounting conditions, alignment and installation and by vibration influences
from an external source may increase the vibration values of the motor.
With a view to correct functioning of the motor and long bearing life, the
vibration values shown in Fig. 5 must not be exceeded. Complete
balancing of the rotor together with the drive element may possibly be
necessary.
2.3 Balancing, drive components
The fitting and removal of drive components (e.g. coupling disc, belt
pulley, gearwheel, etc.) must be carried out with suitable equipment. Use
the threaded hole provided in the end of the shaft (see Fig. 6.1)
Standard motors are supplied dynamically balanced with a full featherkey.
NOTE: Observe the balancing code shown on the rating plate!
(F = balanced with full featherkey)
