Vibrations, balancing
Motors with a keyway are balanced by the manufacturer with a half feather key.
The site vibration response of the system is determined by the output elements, the
mounting conditions, the alignment, the installation and the effects of external vibrations.
This may cause a modification of the motor vibration values.
Output elements
Suitable devices should always be used to push on or pull off the output elements (e.g. the
coupler, gear wheel, belt pulley, Fig. 4).
- Use the tapped hole in the shaft end.
- Heat up the output elements if necessary.
- Use a shim to protect the centering in the shaft end when pulling output elements off.
- If necessary, fully balance the motor with the output elements according to ISO1940
Fig. 4 Pulling off and putting on output elements.

ENGLISH
16 610.40 700.21 Siemens AG
Safety rules for working in electrical installations as per
EN 50110-1 (DIN VDE 0105-100):
- Work always with the equipment electrically dead.
- Isolate from electrical supply.
- Secure against switching on again.
- Check electrical deadness.
- Earth and short-circuit.
- Cover or cordon off adjacent parts which are electrically live.
- Release for work.
- Connect the PE conductor to
Assembly requirements
Pre-assembled cables from SIEMENS are recommended (not included in scope of delivery).
These cables reduce the assembly time and increase operational safety (see project
planning instructions).
- Proper installation is the responsibility of the manufacturer of the system / machine.
- Observe the data on the type plate (Section 3.1)and the information in the wiring
diagrams (Fig. 5).
- Connecting leads must be suitable for the type of application and for the anticipated
currents and voltages.
- If the motor is supplied by means of converters, high-frequency current and voltage
harmonics in the motor supply leads can cause electromagnetic interference to be
emitted.
Use shielded power and signal lines.
Observe the EMC instructions of the converter manufacturer.
- The inside of the plug must be kept clean and free from cable residues and moisture.
- Avoid protruding wire ends.
- Check the seals and sealing surfaces of plug to ensure that the degree of protection is
maintained.
- The connecting leads are to be equipped with the strain relief device and the devices
which protect against rotation and transverse forces, and must be prevented from
kinking. The plugs must not be subjected to continuous forces.
- The coding slot on the plug connector must be aligned when inserted into the female
connector in each case, and the union nut tightened up to the stop by hand.
The protective function with a fitted temperature sensor is inadequate for high thermal loads,
e.g. overload with the motor at a standstill. Additional protective measures are to be provided
for such cases, e.g. a i²t monitoring.
CAUTION
Warning of motor damage!
Connecting the motor directly to a three-phase system will destroy it.
Motors may only be driven with configured converters!
Ensure that the phase sequence is correct.
Encoder systems and temperature sensor contain electrostatically
endangered components (EEC).
Do not touch the connections with your hands or tools which could be
electrostatically charged!

5.3 Motors with DRIVE-CLiQ interface
Motors for the SINAMICS S120 drive system are equipped with a sensor module (electronic
module) which contains the encoder and temperature evaluation and an electronic rating
plate. This sensor module is mounted instead of the signal connector, and has a 10-pole
RJ45plus socket that is known as the DRIVE-CLiQ interface. The pin assignment is
independent of the encoder inside the motor.
Fig. 7 Motor with sensor modul (example)
The signal link between motor and converter is made by a DRIVE-CLiQ cable MOTION-
CONNECT. Only SIEMENS pre-assembled cables may be used. These cables reduce the
assembly time and increase operational safety.
The plug of the DRIVE-CLiQ cable must be pushed on until the catch springs slot in, pay
attention to the plug coding.
WARNING
The motor must not be lifted or transported by the sensor module.
CAUTION
The sensor module has direct contact to electrostatically sensitive devices

- the feather keys in the shaft end (if present) are secured against being thrown out.
6.2 Commissioning procedure
Observe the start up and commissioning instructions for the converter (e.g. SIMODRIVE,
MASTERDRIVES MC, SINAMICS).
1. Release brake, in as far as this is necessary.
2. Check the brake function (open and close).
Apply 24 V DC ±10% to the pins +BD1, -BD2 (Fig. 5), and ensure that the rotor is
running freely (no rubbing noises).
3. Check the mounting, seating and alignment of the motor.
4. Check the suitability and setting of the output elements for the intended conditions of
use, for example belt tension.
5. Check the power and signal plug connections.
6. Check the functional condition of the auxiliary devices present.
7. Check the protection against accidental contact with moving and live parts.
8. Bring the drive system into operation in accordance with the operating manual for the
converter or inverse rectifier.
9. Check that the maximum permissible speed nmax is observed (see type plate for
details). The maximum permissible speed is the highest permissible, short-term
operating speed.
10. The fitted temperature sensor cannot cater for all possible faults (note the instructions
in the Configuration Manual).
WARNING
Hazard from rotating rotor!
Protect the output elements against accidental contact!
Secure feather key (if present) against being thrown out.
NOTICE
The brake is designed as a holding brake. Emergency stops are permitted;
see project planning instructions.
It is not permitted to be used as a working brake.

7 Instructions in case of faults
In case of deviation from normal operation or faults, proceed first according to the following
list:
In this connection, please also refer to the relevant section of the operating manual for the
components of the entire drive system.
Do not disable the protective devices, even in trial operation.
Consult the manufacturer or the SIEMENS service center when necessary.
For start up, system motor converter: A&D Hotline [phone]
For motor / motor components: Contact in the works [phone]
Fault Cause Remedy
Irregular running Inadequate screening of the
motor or encoder cable.
Check screening and grounding (see
Section 5.1)
Amplification of the drive control-
ler too high
Adjust controller (see converter operat-
ing manual)
Vibrations Coupling elements or driven
machine are badly balanced
Rebalance
Inadequate alignment of the drive
train
Realign the machine set
Fixing screws are loose Check and tighten screw connections
Running noises Foreign bodies inside the motor Repair by the manufacturer
Bearing damage Repair by the manufacturer
Motor overheats
(surface temperature
> 140 °C (284 °F))
Temperature monitoring
responds
Drive overloaded Check load (see type plate)
Heat dissipation impaired by
deposits
Clean surface of drives.
Ensure that the cooling air can flow
freely in and out

8 Inspection, maintenance, disposal
Clean according to the degree of local contamination in order to ensure that the waste heat
is adequately dissipated.
As the operating conditions vary greatly, one can only cite general intervals for fault-free
operation.
Also replace the encoders whenever the motor ball bearings are replaced as the encoder
bearings wear out too.
Guidelines:
- Bearing service life 25 000 hours
- Radial shaft seals approx. 10 000 hours with oil lubrication.
Motors must be disposed of carefully taking into account domestic and local regulations in
the normal recycling process or by returning to the manufacturer.
The following must be taken into account when disposing of the motor:
- Oil according to the regulations for disposing of old oil
- Not mixed with solvents, cold cleaning agents of remains of paint
- Components that are to be recycled should be separated according to:
-. Electronics waste (e.g. sensor electronics, sensor modules)
-. Iron to be recycled
-. Aluminum
-. Non-ferrous metal (gearwheels, motor windings)
WARNING
Motor servicing is prohibited unless performed by an approved service work-
shop.
