Safety information/instructions
This manual contains information which you should carefully observe to ensure your own personal safety and to
prevent material damage. The notices referring to your personal safety are highlighted in the manual by a safety
alert symbol, notices referring to property damage only, have no safety alert symbol The warnings appear in
decreasing order of risk as given below.
If several hazards of different degrees occur, the hazard with the highest degree must always be given priority. If a
warning note with a warning triangle warns of personal injury, the same warning note can also contain a warning of
material damage.
Qualified personnel
The associated device/system may only be set up and operated using this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Qualified persons are defined as
persons who are authorized to commission, to ground, and to tag circuits, equipment, and systems in accordance
with established safety practices and standards.
Correct usage

Danger
indicates that death or severe personal injury will result if proper precautions are not taken.
Warning
indicates that death or severe personal injury may result if proper precautions are not taken.
Caution
with a warning triangle indicates that minor personal injury can result if proper precautions are not taken.

Foreword
Table -2: Danger and warning information
Danger and warning information
Danger
Start-up/commissioning is absolutely prohibited until it has been completely ensured that the
machine, in which the components described here are to be installed, is in full compliance
with the specifications of Directive 98/37/EC.
Only appropriately qualified personnel may commission SIMODRIVE and SIMOVERT
MASTERDRIVES drive units and the motors.
This personnel must carefully observe the technical customer documentation associated with
this product and be knowledgeable about and carefully observe the danger and warning infor-
mation.
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels.
When the machine or system is operated, hazardous axis movements can occur.
All of the work carried-out on the electrical machine or system must be carried-out with it in a
no-voltage condition.
SIMODRIVE and SIMOVERT MASTERDRIVES drive units have been designed to be con-
nected to line supplies grounded through a low-ohmic connection (TN line supplies). For addi-
tional information please refer to the appropriate documentation for the drive converter
systems.
Warning
The successful and safe operation ofthis equipment and motors is dependent on professional
transport, storage, installation and mounting as well as careful operator control, service and
maintenance.
For special versions of the drive units and motors, information and data in the catalogs and
quotations additionally apply.
In addition to the danger and warning information/instructions in the technical customer docu-
mentation supplied, the applicable domestic, local and plant-specific regulations and require-
ments must be carefully taken into account.
Caution
The motors can have surface temperatures of over +100 °C.
This is the reason that temperature-sensitive components, e.g. cables or electronic compo-
nents may neither be in contact nor be attached to the motor.
When connecting-up cables, please observe that they
– are not damaged
– are not subject to tensile stress
– cannot be touched by rotating components.

Table -3: ESDS information and instructions
Caution
Motors should be connected-up according to the circuit diagram provided. They must not be
connected directly to the three-phase supply because this will damage them.
SIMODRIVE and SIMOVERT MASTERDRIVES drive units with AC motors are subject, as
part of the type test, to a voltage test corresponding to EN 50178. According to EN 60204-1,
Section 19.4, while electrical equipment of industrial machines are being subject to a voltage
test, all of the SIMODRIVE and SIMOVERT MASTERDRIVES drive unit connections must be
disconnected/withdrawn in order to avoid damaging the SIMODRIVE and SIMOVERT
MASTERDRIVES drive units.
Note
SIMODRIVE and SIMOVERT MASTERDRIVES drive units with motors fulfill, when opera-
tional and in dry equipment rooms, the Low-Voltage Directive 73/23/EEC.
SIMODRIVE and SIMOVERT MASTERDRIVES drive units with motors fulfill, in the configura-
tions specified in the associated EC Declaration of Conformity, EMC Directive 89/336/EEC.

ESDS instructions
Standards, regulations
The appropriate standards, regulations are directly assigned to the functional
requirements.
Caution
An electrostatic-sensitive device (ESDS) is an individual component, integrated circuit, or
module that can be damaged by electrostatic fields or discharges.
ESDS regulations for handling boards and equipment:
When handling components, make sure that personnel, workplaces, and packaging are well
earthed.
Personnel in ESD zones with conductive floors may only touch electronic components if they
are
– grounded through an ESDS bracelet and
– wearing ESDS shoes or ESDS shoe grounding strips.
Electronic boards should only be touched if absolutely necessary.
Electronic boards must not come into contact with plastics or items of clothing containing
synthetic fibers.
Electronic boards may only be placed on conductive surfaces (table with ESDS surface,
conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers).
Electronic boards may not be brought close to data terminals, monitors or television sets.
(minimum clearance >10 cm).
Measurements may only be carried-out on electronic boards and modules if
– the measuring instrument is grounded (e.g. via a protective conductor) or
– before making measurements with a potential-free measuring device, the measuring head
is briefly discharged (e.g. by touching an unpainted blank piece of metal on the control
cabinet).

Motor Description 1
1.1 Overview
Table 1-1: Overview 1FK7 motors are extremely compact, permanently excited synchronous motors. The available
options, gearboxes 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 per-
manently increasing demands of state-of-the-art machine generations.
Together with the SIMODRIVE 611, SIMOVERT MASTERDRIVES MC drive systems, the
1FK7 motors comprise a powerful system with high functionality. The integrated encoder sys-
tems for speed and position control can be selected depending on the application.
The motors are designed for operation without external cooling and the heat is dissipated
through the motor surface. 1FK7 motors have a high overload capability.

1) With SIMODRIVE universal HR, it is important that the maximum encoder frequency of 432 Hz is maintained
(encoder frequency = speed x pole pair number / 60).
Caution
The motors can have surface temperatures of over +100 °C.
Note
The motors must be ordered with a special paint finish if they are to be used in sub-tropical
regions and if they are to be transported by sea. This paint finish prevents the stator core from
corroding.

Motor Description
Cooling, 1FK7
1FK7 Synchronous Motors
1-8 Configuration Manual (PFK7), 10/2005 Edition, 6SN1197-0AD06-0BP1
1.4 Cooling, 1FK7
Cooling version
The cooling version is defined at the 9th position of the motor Order No. (MLFB).
1FK7 motors can be supplied in the natural cooling version:
Natural cooling
Operating temperature range: -15 °C to +40 °C (without any restrictions).
The power loss is dissipated through radiation and natural convection which means that ade-
quate heat dissipation must be ensured by suitably mounting the motor (refer to Chapter
"Motor components (options)").
All of the Catalog data refer to an ambient temperature of 40 °C, mounted so that the motors
are not thermally insulated and an installation altitude up to 1000 m above sea level.
If other conditions prevail (ambient temperature > 40 °C or installation altitude > 1000 m
above sea level), the permissible torque/power must be defined using the factors from the
following table (torque/power reduction according to EN 60034-6).
Ambient temperatures and installation altitudes are rounded-off to 5 °C or 500 m respectively.
