1 General safety instructions
The servomotors correspond to the harmonized standards of the
EN 60034-1, EN 60034-9 and EN 60204-1.
The three-phase servomotors 1FS6 confirm:
73/23/EWG Low Voltage Directive
98/37/EG EC-regulation for machines, appendix II, letter B
(Declaration of manufacturer)
89/336/EWG EC regulation for EMC
94/9/EG ATEX 100a
Ensure that your end product conforms to all currently valid legal requirements.
Follow the compulsory national, local and installation-specific regulations.
Three –phase servomotors are exclusively intended for fitting in another machine or
machines.
These motors must be brought into use it has been established that the end product
conforms to the currently valid directives.
All safety instructions must be observed during the transport, storage, assembly,
disassembly and operation of the servomotors!
The motors rotors contain permanent magnets with high magnetic flux densities which exert
strong attractive forces on ferromagnetic bodies. People fitted with a heart pacemaker are
at risk in the vicinity of a disassembled rotor. Data stored on electronic data media may be
destroyed.
Failure to observe the instructions can lead to serious personal injuries or property
damage.
Thermal hazards
The surface temperatures of the motors can reach up to 140 °C (284 °F).
Do not touch hot surfaces!
Temperature-sensitive components (electric lines, electronic components) must not touch
hot surfaces.
Overheating in the motors may destroy the windings and bearings, and demagnetize the
permanent magnets.
Only operate the motors with effective temperature control!
DANGER
Dismantling motors is strictly forbidden.
All repair and service work will be done exclusive by the
manufacturer.
WARNING
For the operation the internal PTC (DIN 44082) must be connected to
an external and valided cut-off device.

4.1 Transport, storage
Use suitable load suspension devices for transport and assembly. Use lifting eyes for
transporting the motors where these are provided by the manufacturer.
Lifting tackles are per 98/37/EU Directive for machines. Appendix I.
The motors weigh up to 50 kg. For exact details, please refer to the catalog or dimensional
sheet.
Observe the transport regulations applying in the country/countries concerned.
Store in a try-dust and low-vibration place (veff < 0,2 mms-1) .
4.2 Installation
Fig. 2 Types of construction
- Take note of and observe the information on the rating plate and warning and informative
notice on the motor.
- Observe the permitted transverse and axial forces (see enclosure 1).
- Check for compliance with the conditions (e.g. temperature, site altitude) at the assembly
site (see section 3.2).
- Remove all anti-corrosion agents from the shaft end (use commercially available
solvent).
WARNING
Danger during lifting and transporting procedures!
Improper handling, unsuitable or defective devices, tools etc. can
cause injuries and / or property damage.
Lifting devices, ground conveyors and lifting tackle must correspond
to the valid regulations.

- Ensure the waste heat is adequately dissipated.
- It is recommended to maintain a clearance of 100 mm from adjacent parts on the least
three sides.
- Tighten the flange equally, avoid distortions when tightening fixing screws. Use hexagon
socket head cap screws, strength class at least 8.8.
- In the case of a vertical installation with the shaft end at the top, ensure that no fluid
penetrates into the upper bearing.
- Turn the output elements by hand. If grinding noises occur, eliminate the cause or
contact the manufacturer.
Precheck for explosion proof
After checking all datas in the technical standard manuals it is recommended to check all
datas according to regulation of explosion proof e.g.
a) gas group
b) temperatur class
Please note that the motors are classified and certificated according to their group. The
respective group result from the environment gas and the temperature class and is
calculated as a function of the environment temperature of 40°C (104°F).
Vibrations, balancing
Motors with a keyway are balanced by the manufacturer with a half feather key. The site
vibrations 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.
The vibrations immited in the fitted state must not exceed acceleration of 5 g.

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. 3).
- 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 pulling output elements off.
- If necessary, fully balance the motor with the output elements according to ISO1940.

5 Electrical connections
5.1 Important instructions
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.
Assembly requirements
- 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 wring
diagrams (Fig. 4 and 5).
- Connecting leads must be suitable for the type of application and for the anticipated
currents and voltages.
Danger
Electric shock hazard! When the rotor is rotating, the motor
terminals carry a voltage of up to approx. 300V.
Stop the motor before commencing any electrical work. Only use
trained, qualified personnel for assembly work on the converters
an plugs. Observe the regulations for working in electronical
plants and explosion proof !
WARNING
According to the explosion proof regulation the protective conductor
in terminal box as well as the earth terminal on the stator must be
connected.
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!
CAUTION
Encoder systems and temperature sensor contain electrostatically
endangered components (EGB)
. Do not touch the connections with your hands or tools which could be
electrostatically charged!

- For the operation the internal PTC (DIN 44082) must be connected to an external and
valided cut-off device.
- In case of loss of the original screws are only certificated screws permitted.
- The used connecting line have to be certificated for an operation temperature of 100°C
(212°F).
- 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 manufacurer.
- Avoid protruding wire ends.

8 Inspection, maintaince, disposal
Clean according to the degree of local contamination in order to ensure that the waste heat
is adequately dissipated.
As the operating conditions very greatly, one can only cite general intervals for fault-free
operations.
Guidelines:
