Danger!
Disregarding the following basic safety measures may lead to severe
personal injury and damage to material assets!
Note!
Safety−related parameters of safety encoders used can be obtained from
the SISTEMA database, the Lenze AKB (Application Knowledge Base) or
the data sheet of the encoder manufacturer.
¯ Lenze drive and automation components ...
... must only be used for the intended purpose.
... must never be operated if damaged.
... must never be subjected to technical modifications.
... must never be operated unless completely assembled.
... must never be operated without the covers/guards.
... can − depending on their degree of protection − have live, movable or rotating parts
during or after operation. Surfaces can be hot.
¯ Transport and storage in a dry, low−vibration environment without aggressive
atmosphere; preferably in the packaging provided by the manufacturer.
– Protect against dust and impacts.
– Observe climatic conditions according to the technical data.
¯ Lenze drive and automation components ...
... must only be used as intended.
... must never be commissioned despite noticeable damage.
... must never be technically changed.
... must never be commissioned in an incompletely mounted state.
... must never be operated without the required covers.
... may have live, moving or rotary parts during and after operation − corresponding
to their type of protection. Surfaces may be hot.
... must not be operated with large vibrations.

Safety instructions
Application as directed
¯ Only qualified skilled personnel are permitted to work with or on Lenze drive and
automation components.
According to IEC 60364 or CENELEC HD 384, these are persons ...
... who are familiar with the installation, assembly, commissioning and operation of
the product,
... possess the appropriate qualifications for their work,
... and are acquainted with and can apply all the accident prevent regulations,
directives and laws applicable at the place of use.
2.2 Application as directed
Low−voltage machines are not household appliances, but are intended as components
that are only applied for re−use for industrial or professional purposes in terms of
IEC/EN 61000−3−2.
They meet the requirements of the Low−Voltage Directive 2006/95/EC and the
harmonised standards of the IEC/EN60034 series.
2
It is permissible to use low−voltage machines with IP23 protection or less outdoors only
if special protective measures are taken.
Do not use the integrated brakes as fail−safe brakes. It cannot be ruled out that the
braking torque will be reduced due to disruptive factors that cannot be influenced.
¯ Drives
– ... must only be operated under the operating conditions and power limits
specified in this documentation.
– ... comply with the protection requirements of the EC Low−Voltage Directive.
Note!
Generally, all products this documentation is valid for meet the
requirements of the Low−Voltage Directive 2006/95/EC. Products that do
not meet the minimum efficiencies of the EU Directive 640/2009 (and
hence the ErP Directive 2009/125/EC), will not be CE−compliant as of
16th June 2011 and thus do not receive a CE designation.
In that case, the product may only be used outside the EEA.
Any other use shall be deemed inappropriate!

2.3 Foreseeable misuse
¯ Do not operate the motors
Safety instructions
Foreseeable misuse
– ... in explosion−protected areas
– ... in aggressive environments (acid, gas, vapour, dust, oil)
– ... in water
– ... in radiation environments
Note!
Increased surface and corrosion protection can be achieved by using
adapted coating systems.
2.4 Residual hazards
EN
Protection of persons
¯ The motor surfaces can become very hot. Danger of burns when touching!
– Provide protection against accidental contact, if necessary.
¯ Highfrequency voltages can be capacitively transferred to the motor housing
through the inverter supply.
– Earth motor housing carefully.
¯ Danger of unintentional starting or electrical shocks
– Connections must only be made when the equipment is deenergised and the
motor is at standstill.
– Installed brakes are no fail−safe brakes.

Lenze ¯ BA 33.0006 ¯ 3.0
Safety instructions
Motor protection
¯ Installed thermal detectors are no full protection for the machine.
– If required, limit the maximum current, parameterise the controller such that it
will be switched off after some seconds of operation with I > I
there is the danger of blocking.
– Installed overload protection does not prevent an overload under any
conditions.
¯ Installed brakes are no fail−safe brakes.
– The torque can be reduced due to disruptive factors that cannot be influenced,
e.g. by ingressing oil due to a defect shaft sealing ring on the A side.
¯ Fuses are no motor protection.
– Use current−dependent motor protection switches at average operating
frequency.
– Use installed thermal detectors at high operating frequency.
¯ Too high torques cause a fraction of the motor shaft.
– The maximum torques according to catalogue must not be exceeded.
, especially if
N
2
Residual hazards
¯ Lateral forces from the motor shaft may occur.
– Align shafts of motor and driving machine exactly to each other.
¯ If deviations from normal operation occur, e.g. increased temperature, noise,
vibration, determine the cause and, if necessary, contact the manufacturer. If in
doubt, switch off the motor.
Fire protection
¯ Fire hazard
– Prevent contact with flammable substances.

5.1 Important notes
Danger!
Some of the motors mounted to the gearboxes are equipped with
transport aids. They are only intended for the mounting/dismounting of
the motor to the gearbox and must not be used for the entire geared
motor!
¯ Only move the drive with means of transport or hoists that have sufficient
load−bearing capacity.
¯ Ensure safe fixing.
¯ Avoid shocks!
5.2 Preparation

Important notes
Remove the corrosion protection from the shaft ends and flanges. If necessary, remove
dirt using standard cleaning solvents.
Stop!
Bearings or seals must not come into contact with the solvent − material
damages.
After a long storage period (> 1 year) you have to check whether moisture has
entered the motor. For this purpose, measure the insulation resistance (measuring
voltage 500 VDC). In case of values £1kWper volt of rated voltage, dry the winding.
5.3 Assembly of built−on accessories
Follow the instructions below carefully. Please note that, in the event of impermissible
alteration or modification of the motor, you will lose all entitlements to make claims
under warranty and to benefit from product liability obligations.
¯ Mount the transmission elements:
– Shocks and impacts must be avoided! They could destroy the motor.
– Always use the centre bore in the motor shaft (in accordance with DIN 332,
design D) for mounting.
– Tolerances of the shaft ends:
£ Æ 50 mm: ISO k6, > Æ 50 mm: ISO m6.
EN
¯ Only use an extractor for the disassembly.
¯ When using belts for torque/power transmission:
– Tension the belts in a controlled manner.
– Provide protection against accidental contact! During operation, surface
temperatures of up to 140°C are possible.

– Incorrect motor alignment reduces the service life of the roller bearings and
transmission elements.
Impacts on shafts can cause bearing damage.
¯ Do not exceed the permissible range of ambient operating temperature ( 19).
¯ Fasten the motor securely.
¯ Ensure that the ventilation is not impeded. The exhaust air, also the exhaust air of
other machines next to the drive system, must not be taken in immediately.
¯ During operation, surfaces are hot, up to 140 °C! Ensure that guard preventing
accidental contact is in place!
EN
Ensure an even surface, solid foot/flange mounting and exact alignment if a direct
clutch is connected. Avoid resonances with the rotational frequency and double mains
frequency which may be caused by the assembly.
Use appropriate means to mount or remove transmission elements (heating) and cover
belt pulleys and clutches with a touch guard. Avoid impermissible belt tensions.
Stop!
The machines are halfkey balanced. The clutch must be halfkey balanced, too. The
visible jutting out part of the key must be removed.
Designs with shaft end at the bottom must be protected with a cover which prevents
the ingress of foreign particles into the fan.
5.4 Holding brake (option)
Important notes
As an option, the motors can be fitted with a brake. The installation of brakes (in or on
the motor) increases the length of the motor.
Ensure a correct belt tension!
Note!
The brakes used are not fail−safe because interference factors, which
cannot be influenced (e.g. oil ingress), can lead to a reduction in torque.
The brakes are used as holding brakes and serve to hold the axes at standstill or in the
deenergised state.
Emergency stops at higher speeds are possible, but high switching energy increases
wear on the friction surfaces and the hub (see wear of brakes, page 25 and 26).

The brakes operate according to the closed−circuit principle, i.e. the brake is closed in the
deenergised state. The brakes for DC supply can be fed with a bridge−rectified DC
voltage (bridge rectifier) or with a smoothed DC voltage. Information on the permissible
voltage tolerance is provided in the respective motor catalogue.
If long motor supply cables are used, pay attention to the ohmic voltage drop along the
cable and compensate for it with a higher voltage at the input end of the cable.

Stop!
If no suitable voltage (incorrect value, incorrect polarity) is applied to the
brake, the brake will be applied and can be overheated and destroyed by
the motor continuing to rotate.
The shortest operating times of the brakes are achieved by DC switching of the voltage
and a suppressor circuit (varistor or spark suppressor). Without suppressor circuit, the
operating times may increase. A varistor/spark suppressor limits the breaking voltage
peaks. It must be ensured that the power limit of the suppressor circuit is not exceeded.
This limit depends on the brake current, brake voltage, disengagement time and the
switching operations per time unit.
Furthermore, the suppressor circuit is necessary for interference suppression and also
increases the service life of the relay contacts (external, not integrated in the motor).
Please refer to the catalogue for servo motors for detailed information
about holding brakes.

Note!
The brake cannot be readjusted. When the wear limit is reached, the
brake has to be replaced.

5.4.1 Permanent magnet holding brakes
These brakes are used as holding brakes and serve to hold the axes without backlash at
standstill or in the deenergised state.
When activating the brake, it must be ensured that the brake is released or engaged at
zero speed to avoid unnecessary and rapid wear of the brake.
When used solely as holding brakes, the brakes are virtually wear free on their friction
surfaces. If the max. permissible switching energy per emergency stop (see catalogue)
is not exceeded, at least 2000 emergency stop functions from a speed of 3000 rpm are
possible.

These brakes operate according to the closed−circuit principle, i.e. the brake is closed in
the deenergised state.
Brakes with a rated voltage of DC 24 V are designed for smoothed DC voltages with a
ripple of <1 %. It must be ensured that the connector on the motor side is supplied with
the minimum voltage of DC 24 V −10 %. If necessary, the voltage drop in the cable should
also be considered. If the maximum voltage DC 24 V + 5 % is exceeded, the brake can
close again. Supplying the brake with bridge−rectified DC voltage (bridge rectifier
without additional smoothing) or a DC voltage with a ripple of >1 % can lead to a
malfunctioning of the brake or an increase in the engagement and disengagement
times.
Brakes with a rated voltage of DC 205 V are designed for bridge−rectified DC voltage, i.e.
for supply via a bridge rectifier from the 230 V mains (half−wave rectifiers are not
permissible). Supplying the brake with smoothed DC voltage can lead to
malfunctioning or an increase in the engagement and disengagement times. With
regard to the minimum and maximum voltages, the same conditions apply as for brakes
with 24 V, i.e. the permissible voltage tolerance is 205 V DC +5 %, −10 %.

Wear on spring−applied brakes
Spring−applied brakes of the INTORQ BFK458, BFK460 series and the spring−applied
brake of the MQA motors are wear resistant and designed for long maintenance
intervals.
However, the friction lining, the teeth between the brake rotor and the hub, and also the
braking mechanism are naturally subject to function−related wear which depends on
the application case (see table). In order to ensure safe and problem−free operation, the
brake must therefore be checked and maintained regularly and, if necessary, replaced
(see brake maintenance and inspection).
The following table describes the different causes of wear and their effect on the
components of the spring−applied brake. In order to calculate the useful life of the rotor
and brake and determine the maintenance intervals to be prescribed, the relevant
influencing factors must be quantified. The most important factors are the applied
friction energy, the starting speed of braking and the switching frequency. If several of
the indicated causes of wear on the friction lining occur in an application, their effects
are to be added together.

– Safe stop 1 (SS1)
– Safe operational stop (SOS)
– Safely limited speed (SLS)
– Safe maximum speed (SMS)
– Safe direction (SDI)
– Safe speed monitor (SSM)

A "two−encoder concept" includes e.g. a resolver as motor encoder and, at the same time,
an absolute value encoder (sin/cos), an incremental encoder (TTL), or digital encoder
(SSI/bus) as position encoder on the machine.
In the case of the "2−encoder concept", the achievable risk mitigation (PL/SIL) depends on
the suitability of the encoders used.
Note!
If feedback systems for safety functions are used, the manufacturer’s
documentation must be observed!

8.1 Important notes
For trial run without output elements, lock the featherkey. Do not deactivate the
protective devices, not even in a trial run.
Check the correct operation of the brake before commissioning motors with brakes.
8.2 Before switching on
Note!
Before switch−on, you must ensure that the motor starts with the
intended direction of rotation.
Lenze motors rotate CW (looking at the driven shaft) if a clockwise
three−phase field L1 U1, L2 V1, L3 W1 is applied.
8
Important notes
Before initial commissioning, before commissioning after an extended standstill
period, or before commissioning after an overhaul of the motor, the following must be
checked:
¯ Measure the insulation resistance, in case of values £1 kWper volt of rated
voltage, dry the winding.
¯ Have all screwed connections of the mechanical and electrical parts been firmly
tightened?
¯ Is the unrestricted supply and removal of cooling air ensured?
¯ Has the PE conductor been connected correctly?
¯ Have the protective devices against overheating (temperature sensor evaluation)
been activated?
¯ Is the controller correctly parameterised for the motor?
( Controller operating instructions)
¯ Are the electrical connections o.k.?
¯ Does the motor connection have the correct phase sequence?
¯ Are rotating parts and surfaces which can become very hot protected against
accidental contact?
¯ Is the contact of good electrical conductivity if a PE connection on the motor
housing is used?

9.1 Important notes
Danger!
Hazardous voltage on the power connections even when disconnected
from mains: residual voltage >60 V!
Before working on the power connections, always disconnect the drive
component from the mains and wait until the motor is at standstill.
Verify safe isolation from supply!
Stop!
Repair work or replacement of defective safety encoders must only be
carried out by Lenze service personnel!
Shaft sealing rings and roller bearings have a limited service life.
Regrease bearings with relubricating devices while the low−voltage machine is running.
Only use the grease recommended by the manufacturer. If the grease drain holes are
sealed with a plug, (IP54 drive end; IP23 drive and non−drive end), remove plug before
commissioning. Seal bore holes with grease.

9.2 Maintenance intervals
Inspections
¯ If the machine is exposed to dirt, clean the air channels regularly.
9.2.1 Motor
¯ Only the bearings and shaft sealing rings become worn.
– Check bearings for noise (after approx. 15,000 h at the latest).
¯ In order to prevent overheating, remove dirt deposits on the drives regularly.
¯ We recommend carrying out an inspection after the first 50 operating hours. In
this way, you can detect and correct any irregularities or faults at an early stage.
9.2.2 Safety encoder
After a service life of 10 years, an inspection of the metal elastomer torque plate is
required for the encoders AS1024−8V−K and AM1024−8V−K. If no replacement is
required, an inspection interval of max. 5 years has to be observed.

9.2.3 Holding brake
The brakes need to be checked on a regular basis to ensure safe and trouble−free
operation.
The necessary maintenance intervals primarily depend on the stress to which the brake
is subjected in an application. When a maintenance interval is being calculated, all
causes of wear must be taken into account (see notes "Wear on spring−applied brakes").
In the case of brakes which are subjected to low levels of stress, e.g. holding brakes with
emergency stop function, regular inspections at a fixed time interval are recommended.
In order to reduce the amount of work involved in maintenance, perform the inspection
at the same time as other maintenance work carried out cyclically on the machine if
possible.
If the brakes are not properly serviced, operating faults, production outages or damage
to machinery can occur. A maintenance concept adapted to the operating conditions
and the stresses to which the brakes are subjected must therefore be drawn up for every
application. For brakes, the maintenance intervals and servicing work listed in the
following table are necessary.
Maintenance/repair

The brakes of the MCS, MCA, MQA, and MDKS motors cannot be accessed from the
outside! (Maintenance work on the brakes must be carried out by Lenze Service staff
only!)

¯ Only work on the drive system when it is in a deenergised state!
¯ Hot motor surfaces of up to 150 °C. Observe cooling times!
¯ Remove loads acting on motors or secure loads acting on the drive!
9.3.1 Blower
If the motor is equipped with a dust protection filter, this filter must be cleaned or even
replaced at regular intervals depending on the amount of dust (if necessary, daily).
For motors equipped with a dry filter, the dust must be shaken out completely. If the
dust is wet, the filter mat must be replaced.

Fan with dust protection filter
9.3.2 Fan with dust protection filter
Dry−type filters are used for the motors. Dry dust should be removed completely by
tapping.
Note!
The dust filter is mounted on the ventilation aggregate. Depending on
the amount of dust, the filter must be cleaned and replaced in regular
intervals!
Soiled filters reduce the amount of cooling air significantly. This leads to a higher
winding temperature, reduces its service life and may lead to damages.
When replacing the filter you must take care that all covers and filters are tightly fixed
so that there are no leaks for harmful dust!
In case of wet dust you must install new filter mats. The internal cleanness of the motor
should be checked at the latest when you replace the filter for the first time.
