Safety instructions 2
2.1 General safety notes
Safety and commissioning information for converter-fed low-voltage three-phase motors
DANGER
All activities associated with transporting, connecting, commissioning, and maintaining the
motors must be carried out by properly trained, responsible personnel (observe DIN EN
50110-1; IEC 60364).
Failure to follow proper procedures may result in injury or material damage.
Special versions and design versions may differ with respect to certain technical aspects. If
in doubt, you are strongly advised to contact the manufacturer, specifying the type
designation and serial number (see rating plate), or arrange for any maintenance work to be
carried out by the SIEMENS Service Center.
Systems and machines with converter-fed low-voltage three-phase motors must fulfill the
protective requirements of the EMC Directive.
The machine manufacturer is responsible for ensuring that installation is carried out properly.
The signal and power cables to the motor must be shielded.
The information provided by the converter manufacturer regarding EMC-compliant
installation must be observed.
Intended use
These motors are designed for use in industrial or commercial systems. They comply with
the EN 60034-1 standards and the relevant associated sections.
WARNING
It is forbidden to install them in hazardous areas unless they are explicitly designed for this.
If more stringent requirements are necessary in special cases (e.g. shock-hazard protection
in non-commercial applications where children are likely to be present), the customer must
implement the relevant measures to ensure that these requirements are fulfilled.
Any alternative data specified on the rating plate must be taken into account. The conditions
at the installation location must comply with the rating plate specifications.
The motors are designed for use in sheltered areas under normal climatic conditions, such
as those found in production environments.

2.2 Safety and application instructions
The safe use of electrical machines
WARNING
Rotating or live parts
Rotating or live parts are dangerous.
Fatal or severe injuries and substantial material damage can occur if the necessary covers
are removed or if the machines are not handled, operated, or maintained properly.
Covers must only be removed and the motor operated in accordance with the relevant
regulations. The motor must be maintained on a regular basis.
Qualified personnel
These operating instructions only contain the information necessary for ensuring that the
motor is operated by properly trained personnel in accordance with its intended purpose.
Those responsible for plant safety must ensure the following:
● The basic planning work for the plant or system and all work relating to transportation,
assembly, installation, commissioning, maintenance and repairs is carried out by qualified
personnel and checked by responsible, suitably skilled personnel.
● The operating instructions and the motor documentation are available at all times.
● The technical data and specifications relating to installation, connection, ambient and
operating conditions are taken into account at all times.
● The system-specific installation and safety regulations are observed.
● Personal protective equipment is used.
● Unqualified persons must not work on or in the vicinity of these motors at any time.
● If the motors are used outside industrial areas, the installation site must be protected
against unauthorized access by means of suitable protective measures (e.g. safety
fences and warning signs).
Note
Siemens Service Center
For any service work you may require, you are advised to contact your nearest Siemens
Service Center to request their services and support for maintenance activities.

2.2 Safety and application instructions
Synchronous Motors 1FK7
Operating Instructions, 03/2011, 610.40700.40c 9
Observing the five safety rules
For your personal safety and to prevent material damage when working on the machine,
always observe the safety instructions and the following five safety rules. Apply the five
safety rules in the order stated before starting work at the machine.
1. Isolate the equipment from the power supply
You must also make sure that the auxiliary circuits are also disconnected.
2. Protect against reconnection.
3. Make sure that the equipment is de-energized and in a no-voltage condition.
4. Ground and short-circuit
5. Cover or enclose adjacent components that are still live.
After the work has been completed, undo the previous measures in the reverse order.
Thermal hazard
CAUTION
The surface temperature of the motors can exceed 100 °C.
Do not touch hot surfaces!
Temperature-sensitive components (electric cables, electronic components) must not be
placed on hot surfaces. If the motors overheat, this can destroy the windings/bearings and
permanent magnets may become demagnetized.
Only operate the motors in conjunction with effective temperature monitoring!

Notes about electromagnetic fields
WARNING
Electromagnetic fields
Electromagnetic fields are generated by the operation of electrical power equipment – such
as transformers, converters or motors.
Electromagnetic fields can destroy electronic devices, which could cause them to
malfunction. For example, the operation of heart pacemakers can be impaired, potentially
leading to personal injury or even death. It is therefore forbidden for persons with heart
pacemakers to enter these areas.
The company operating the plant is responsible for taking appropriate measures (labels
and hazard warnings) to adequately protect operating personnel and others against any
possible risk.
● Observe the relevant local and domestic health and safety regulations. In Germany,
"electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by
the German statutory industrial accident insurance institution.
● Display adequate hazard warning notices.
● Place barriers around hazardous areas.
● Take measures, e.g. using shields, to reduce electromagnetic fields at their source.

Description 3
3.1 Product description
Overview
1FK7 motors are compact permanent-magnet synchronous motors. The available options,
gear units and encoders, together with the expanded product range, mean that the 1FK7
motors can be optimally adapted to any application. They therefore also satisfy the
permanently increasing demands of state-of-the-art machine generations.
1FK7 motors can be combined with the SINAMICS S120 drive system to create a high-
performance system with a high degree of functionality. The integrated encoder systems for
speed and position control can be selected depending on the application.
The motors are designed for operation without external ventilation as the heat is dissipated
through the motor surface. 1FK7 motors have a high overload capability.
Benefits
1FK7 Compact motors offer:
● Space-saving installation thanks to extremely high power density
● Can be universally used for many applications
● Wide range of motors
1FK7 High Inertia motors offer:
● Rugged closed-loop control properties for high or variable load moments of inertia
● Low optimization and commissioning overhead to compensate disturbances
Applications
● Machine tools
● Robots and handling systems
● Wood, glass, ceramics and stone working
● Packaging, plastics and textile machines
● Auxiliary axes
