Transportation, Storage; Installation; Balancing, Drive Components; Electrical Connections - Siemens 1FT5 062 Manual Del Usuario

Additional fittings and attachments (to order) included
- Encoder systems such as incremental encoders (e.g. ROD 320,
ROD 426), absolute value encoder, etc.
- Separately driven fans
- 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 motors are fitted with lifting lugs, these should be used for lifting and
transporting the motors. 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. In the case of motors with separately driven fans, the filter box
should be cleaned if necessary.
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 or the shaft
end face!
(F = balanced with full featherkey)
(H = balanced with special-design half featherkey)
The balancing code is indicated only if a keyway is provided in the shaft
end. When fitting drive components, check for matching rotor balance
specifications!
Special design
(balanced with half featherkey)
In the case of drive components with a ratio of hub length l to shaft-end
length l of < 0.8 and speeds > 1500 rpm, the motor may run with an
M
unbalance (see Fig. 6.2).

It may be necessary to re-balance the unit, for example by removing that
part of the featherkey, T
P
stands proud of the shaft.
The general safety precautions regarding
prevention of contact with the drive
components. If a motor is put into operation without a drive
component attached, the featherkey must be secured so it is not
thrown out of its slot.
The permissible transverse and axial forces are specified in the diagrams
included in the description of the "SIMODRIVE 1FT5" (if necessary, ask
your local supplier or the manufacturer).
If axial forces act towards the motor, the drive component must rest
against the shoulder of the shaft. If necessary, fit a spacer bush!
There must be no axial forces acting on motors
with an integral brake!

2.4 Electrical connections

The system must be disconnected from the
power supply before any work is carried out!
Due to the fact that the motors contain perma-
nent magnets, a voltage is generated at the motor terminals when
the rotor is turned.
The motor must be connected up as shown in the diagram supplied. For
standard motors, the connections are as shown in Fig. 2.
Basic rules for connecting motors:
- The connecting leads should be suitable for the type of use, as well as
the voltages and amperages concerned.
- The connecting leads should be of sufficient length, and should be
secured against twisting, tensional stress and kinking.
- The protective earth must be connected to the terminal marked
When using a plug connector, make sure that
- the male connector engages properly in the keying slot, and that
- the connector union nut is hand-tight to ensure proper electrical contact
and that the connection is properly sealed.
When connecting to a terminal box, also make sure that
- just enough insulation is removed from the ends of the wires to enable
the wires to fit into the terminals/lugs;
- the size of the lugs matches the dimensions of the terminal board
connections, use parallel connecting wires if necessary;
- the protective earth is connected;
- the inside of the terminal box is clean and free of wire cuttings;
- all electrical screw connections/terminal board connections (except
terminal strips) are tightened to the specified tightening torque, see
Fig. 4;
- the minimum separation of 5.5 mm for non-insulated current-carrying
components is maintained. Check for protruding wire ends!
- unused terminals are sealed and the seals screwed down tightly;
- all sealing faces on the terminal box are in good order to ensure
compliance with the degree of protection!

2.4.1 Power connections

The power is connected via the terminal box or a plug.
Direct connection to the three-phase AC supply
is not allowed and will lead to the destruction
of the motor.
Check for correct phase sequence!
The motor may only be operated from a properly matched pulse-width-
modulation inverter.
