2.1 General safety instructions for drive com ponents
А Danger!
Disregarding the follo w in g basic safety measures may lead to severe
personal injury and damage to m aterial assets!
1Note!
Safety-related param eters o f 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 autom ation com ponents ...
... m ust only be used for the intended purpose.
... m ust never be operated if damaged.
... m ust never be subjected to technical modifications.
... m ust never be operated unless com pletely assembled.
... m ust never be operated w ithou t 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 environm ent w ithout aggressive
atm osphere; preferably in the packaging provided by the m anufacturer.
- Protect against dust and im pacts.
- Observe clim atic conditions according to the technical data.
Lenze drive and autom ation com ponents ...
... m ust only be used as intended.
... m ust never be com missioned despite noticeable damage.
... m ust never be technically changed.
... m ust never be com m issioned in an incom pletely m ounted state.
... m ust never be operated w ithou t the required covers.
... m ay have live, m oving or rotary parts during and after operation - corresponding
to their type of protection. Surfaces m ay be hot.
... m ust not be operated w ith large vibrations.
... m ust not be operated in the frequency range of a plant or the drive system.
All specifications of the corresponding enclosed docum entation must be
observed.
This is vital for a safe and trouble-free operation and for achieving the specified
product features.

Safety instructions 2
Application as directed
O n ly qualified skilled personnel are perm itted to w ork w ith or on Lenze drive and
autom ation components.
According to IEC 60364 or CENELEC HD 384, these are persons ...
... w ho are fam iliar w ith the installation, assembly, comm issioning and operation of
the product,
... possess the appropriate qualifications for their work,
... and are acquainted w ith 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 com ponents
tha t are only applied for re-use for industrial or professional purposes in term s of
IEC/EN 61000-3-2.
They meet the requirem ents of the Low -Voltage Directive 2006/95/EC and the
harmonised standards o f the IEC/EN 60034 series.
It is permissible to use low-voltage machines w ith 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 w ill be reduced due to disruptive factors that cannot be influenced.
Drives
- . .. m ust only be operated under the operating conditions and power lim its
specified in this docum entation.
- . .. com ply w ith the protection requirem ents of the EC Low -Voltage Directive.
1Note!
Generally, all products this docum entation is valid for meet the
requirem ents of the Low -Voltage Directive 2006/95/EC. Products that do
not meet the m inim um efficiencies o f the EU Directive 640/2009 (and
hence the ErP Directive 2009/125/EC), w ill not be CE-com pliant as of
16th June 2011 and thus do not receive a CE designation.
In that case, the product m ay o nly be used outside the EEA.
A n y other use shall be deemed inappropriate!

Foreseeable misuse
2.3 Foreseeable misuse
Do not operate the motors
- . .. in explosion-protected areas
- . .. in aggressive environm ents (acid, gas, vapour, dust, oil)
- . .. in w ater
- . .. in radiation environm ents
1Note!
Increased surface and corrosion protection can be achieved by using
adapted coating systems.
2.4 Residual hazards
Protection o f persons
The m otor 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 m otor housing
through the inverter supply.
- Earth m otor housing carefully.
Danger of unintentional starting or electrical shocks
- Connections m ust only be made when the equipm ent is deenergised and the
m otor is at standstill.
- Installed brakes are no fail-safe brakes.
10 Lenze BA 33.0006 3.0
Safety instructions 2
Residual hazards
M o tor protection
Installed therm al detectors are no full protection for the machine.
- If required, lim it the m axim um current, param eterise the controller such th at it
w ill be switched off after some seconds of operation w ith I > In, especially if
there is the danger o f 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 m otor protection.
- Use current-dependent m otor protection switches at average operating
frequency.
- Use installed therm al detectors at high operating frequency.
Too high torques cause a fraction of the m otor shaft.
- The m axim um torques according to catalogue must not be exceeded.
Lateral forces from the m otor shaft m ay occur.
-A lig n shafts o f m otor and driving m achine exactly to each other.
If deviations from normal operation occur, e.g. increased tem perature, noise,
vibration, determine the cause and, if necessary, contact the manufacturer. If in
doubt, switch o ff the m otor.
Fire protection
Fire hazard
- Prevent contact w ith flam m able substances.

General data and operating conditions
Setting the sw itching frequency to the rated m otor data
4.1.1 Setting the sw itching frequency to the rated m otor data
The rated data are valid for operation on an inverter w ith a switching frequency of at
least 8 kHz. If operated at a sw itching frequency of fch=4 kHz, the follow in g
consequences must be observed.
Motor type Consequences
MDFQA 160 At fch = 4 kHz, the motor continuously reaches only approx. 95 %
of its rated torque.
Strongly increased noise emission
MQA 20, 22, 26
MCA 20, 22, 26 At fch = 4 kHz, the motor continuously reaches only approx. 95 %
of its rated torque.
Increased noise emission
MCS
MCA 10, 13, 14, 17, 19, 21

Im portant notes
5.1 Im p ortant notes
Some of the m otors m ounted to the gearboxes are equipped w ith
transport aids. They are o n ly intended for the m ounting/dism ounting of
the m otor to the gearbox and must not be used for the entire geared
m otor!
O nly move the drive w ith means o f transport or hoists th at have sufficient
load-bearing capacity.
Ensure safe fixin g.
Avoid shocks!
5.2 Preparation
Remove the corrosion protection from the shaft ends and flanges. If necessary, rem ove
dirt using standard cleaning solvents.
@ Stop!
Bearings or seals must not come into contact w ith the solvent - m aterial
damages.
Afte r a long storage period (> 1 year) you have to check w hether m oisture has
entered the m otor. For this purpose, measure the insulation resistance (m easuring
voltage 500 Vdc). In case o f values <1kQper volt of rated voltage, dry the w inding.
5.3 Assem bly o f built-on accessories
Follow the instructions below carefully. Please note that, in the event of im perm issible
alteration or m odification of the motor, you w ill lose all entitlem ents to make claim s
under w arranty and to benefit from product liability obligations.
M ount the transm ission elem ents:
- Shocks and im pacts must be avoided! They could destroy the m otor.
-A lw a y s use the centre bore in the m otor shaft (in accordance w ith DIN 332,
design D) for m ounting.
- Tolerances of the shaft ends:
<0
50 mm: ISO k6, >
0
50 mm: ISO m6.
O nly use an extractor fo r the disassembly.
W hen using belts for torque/pow er transm ission:
- Tension the belts in a controlled manner.
- Provide protection against accidental contact! During operation, surface
tem peratures of up to 140°C are possible.
