Power Connections; Signal Connection - Siemens 1FT6 06 Manual Del Usuario

2.4.1 Power connections

The power is connected via 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.

2.4.2 Signal connection

The sensor system and temperature sensor are connected via the
standard signal connector. Take note of the specifications on the rating
plate and the circuit diagram.
2.4.3 Brake connections
The brake is connected via the power connector. The fail-safe permanent-
magnet holding brake operates according to the closed-circuit principle.
It is released when a current of 24 V DC ± 10% is applied. The voltage
must be between the specified tolerance limits, otherwise reliable operation
may be at risk. When the motor is switched on, the brake must always be
energized, i.e. released. When the brake is switched off (de-energized),
or if there is a power failure, the brake hub is pulled towards the magnet,
thus preventing the motor shaft from moving.
NOTE: In the event of a power failure, the motors can be decelerated by
means of rheostatic-plug braking. In this case, the short-circuit current
must be connected across the R
manual.
2.5 Commissioning
Before putting the motor into operation, check that
- the rotor can be turned without touching the stator (release brake if
necessary);
- the motor is properly fixed and aligned;
- the drive components are correctly adjusted (e.g. belt tension on belt
drive, etc.);
- all electrical connections and connectors match the specifications and
are properly tightened;
- the protective earth is properly connected;
- all attachments (brake,...) are operational
- appropriate measures have been taken to prevent contact with moving
and live parts
- the maximum speed n , if specified (see rating plate), cannot be
max
exceeded
NOTE: The maximum speed n
permissible for a short period.
After installing the motor, check that the
brake (if fitted) works properly! The brake
is only designed to carry out a limited
number of emergency braking operations. It must not be used as
a regular service brake.
This list may be incomplete. Other checks may also be necessary.
Adjustments
If the rotor needs to be turned while the motor is switched off, the brake
must be energized (24 V DC ± 10%, check for correct polarity!), i.e. the
brake must be released.

3 Maintenance
Safety precautions
disconnect the motor from the power supply. Remember to
disconnect any supplementary or auxiliary circuits as well as
the main circuits.
The standard "5 safety rules" according to DIN VDE 0105
apply:
- Disconnect from the power supply
- Secure against reconnection
- Check that equipment is dead
- Earth and short-circuit
- Cover or screen off all live adjacent parts
The above actions may only be reversed when all repair work
has been completed and the motor has been completely re-
assembled.
motors contain permanent magnets, a voltage is generated at the
motor terminals when the rotor is turned.
Replacing the bearings, types of grease
We recommend that the bearings be replaced after approx. 20,000 hours
of operation or after 3 years at the latest. The motors have permanently
lubricated bearings with radial clearance C3 and seals or covers at both
ends. The bearings must be suitable for operation at temperatures
between -15°C and +150°C.
Types of grease for standard motors: UNIREX N3 (Esso); replacement
grease must conform to DIN 51825/K3N.
NOTE: When replacing bearings, the new bearings should have
good seals which match the quality of the original bearings. Check
the bearing inscription and orientation of D-end and N-end bearings!
We recommend that replacement bearings be ordered from the
manufacturer so that special requirements such as bearing clearance
and/or seal material can be taken into account.
Note on Maintenance
We recommend that repair work be carried out by a SIEMENS
Service Center!
A maintenance manual with detailed instructions for qualified
personnel (for definition of qualified personnel, see DIN VDE 0105
or IEC 364) can be ordered from the manufacturer under
Order No. 610.43411.02
Edition: GERMAN-ENGLISH
This maintenance manual contains instructions for removing/
installing
- the separately driven fan
- the resolver and encoder sensor systems
- the motor rotor, including bearing replacement
- the motor rotor, including bearing replacement for motors with
brake
- adjustment of the resolver, encoder.
Before carrying out any work on
the motor or unit, and especially
before uncovering live parts,
The system must be disconnected from
the power supply before any work is
carried out! Due to the fact that the
