Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, commissioning and maintenance. Properly qualified personnel are
persons who are familiar with the transport, assembly, installation, commissioning
and operation of motors, and who have the appropriate qualifications for their jobs.
The qualified personnel must know and observe the following standards and
regulations:
IEC 364 resp. CENELEC HD 384 or DIN VDE 0100
IEC-report 664 or DIN VDE 0110
national regulations for safety and accident prevention or BGV A2

Read the available documentation before assembly and commissioning. Incorrect
handling of the motors can result in injury and damage to persons and machinery.
Keep strictly to the technical data and the information on the connection
requirements (nameplate and documentation).
It is vital that you ensure that the motor housing is safely earthed to the
PE(protective earth) busbar in the switch cabinet. Electrical safety is impossible
without a low-resistance earth connection.
Do not unplug any connectors during operation. This creates the danger of death,
severe injury, or extensive material damage.
Power connections may be live even when the motor is not rotating. Never
disconnect the power connections of the motor while the equipment is energised.
This can cause flashovers with resulting injuries to persons and damage to the
contacts.
After disconnecting the servo-amplifier from the supply voltage, wait at least five
minutes before touching any components which are normally live (e.g. contacts,
screw connections) or opening any connections.
The capacitors in the servo-amplifier can still carry a dangerous voltage up to five
minutes after switching off the supply voltages. To be quite safe, measure the
DC-link voltage and wait until the voltage has fallen below 40V.
The surfaces of the motors can be very hot in operation, according to their
protection category. The surface temperature can reach 100°C. Measure the
temperature, and wait until the motor has cooled down below 40°C before touching
it.
l
Remove any fitted key (if present) from the shaft before letting the motor run
independently, to avoid the dangerous results of the key being thrown out by
centrifugal forces.

Important Notes

l
Servomotors are precision equipment. The flange and shaft are especially
vulnerable during storage and assembly — so avoid brute force. Precision requires
delicacy. It is important to use the locking thread which is provided to tighten up
couplings, gear wheels or pulley wheels and warm up the drive components, where
possible. Blows or the use of force will lead to damage to the bearings and the
shaft.
Wherever possible, use only backlash-free, frictionally-locking collets or couplings,
e.g. from the manufacturers Baumann & Cie, Gerwah, Jacob, KTR or Ringspann.
Ensure correct alignment of the couplings. A displacement will cause unacceptable
vibration and the destruction of the bearings and the coupling.
l
l

l
For toothed belts, it is vital to observe the permissible radial forces. An excessive
radial load on the shaft will significantly shorten the life of the motor.
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly
shortens the life of the motor.
In all cases, do not create a mechanically constrained motor shaft mounting by
using a rigid coupling with additional external bearings (e.g. in a gearbox).
For mounting style V3 (shaft end upwards), make sure that no liquid can enter the
upper bearing.
Take note of the no. of motor poles (6-pole) and the no. of resolver poles (2-pole),
and ensure that the correct setting is made in the servo-amplifier which is used. An
incorrect setting can lead to the destruction of the motor, especially with small
motors.

This Manual is intended for the use of qualified staff with professional knowledge
of electrical and mechanical engineering.
The motors are operated in drive systems together with servo-amplifiers SERVOSTAR™
600. Please observe the entire system documentation, consisting of:
— Installation and commissioning instructions for the servo-amplifier
— Installation and commissioning instructions for any expansion card which is connected
— Operating manual for the Operator Software of the servo-amplifier
— Technical description of the DBL/DBK series of motors
I.2Prescribed usage
The DBL/DBK series of synchronous servomotors is designed especially for drives for
industrial robots, machine tools, textile and packing machinery and similar with high
requirements for dynamics.
The user is only permitted to operate the motors under the ambient conditions which are
defined in this documentation.
The DBL/DBK series of motors is exclusively intended to be driven by servo-amplifiers
from the SERVOSTAR™ 600 series under speed and / or torque control.
The motors are installed as components in electrical apparatus or machines and can only
be commissioned and put into operation as integral components of such apparatus or
machines.
The motors must never be connected directly to the mains supply.
The thermal contact which is integrated in the motor windings must be observed and
evaluated.
The conformity of the servo-system to the standards mentioned in the manufacturers
declaration on page 6 is only guaranteed when the components (servo-amplifier, motor,
leads etc.) that are used have been supplied by us.
Motor series DBL/DBK7
General05/2001Danaher Motion
I.3Design of the motors
Synchronous servomotors in the DBL/DBK series are brushless DC motors for demand
ing servo applications. When combined with our digital servo-amplifiers they are espe
cially suited for positioning tasks in industrial robots, machine tools, transfer lines etc.
With high requirements for dynamics and stability.
The servomotors have permanent magnets in the rotor. The rare earth neodymium
-iron-boron magnetic material is an important factor in making it possible to drive these
motors in a highly dynamic fashion. A three-phase winding which is driven by the
servo-amplifier is integrated into the stator. The motor does not have any brushes since
commutation is performed electronically by the servo-amplifier.
The temperature of the winding is monitored by temperature sensors in the stator wind
ings and is signalled via an electrically isolated contact (normally closed).
A resolver is built into the motors as standard feedback element. The servo-amplifiers in
the SERVOSTAR™ 600 series evaluate the resolver position and supply sinusoidal cur
rents to the motors.
The motors can be delivered with or without a built-in holding brake. Retrofitting of the
brake is not possible.
The motors are enamelled in matt black (RAL 9005). This finish is not resistant against
solvents (e.g. trichlorethylene, nitro-thinners, or similar).

I.5Standard features
I.5.1Style
The basic style for the DBL/DBK synchronous motors is style IM B5 according to
DIN42950. The permitted mounting positions may be read from the technical data of the
motor series.
I.5.2Shaft end, A-side
Power transmission is made through the cylindrical shaft end A (fit k6) to DIN 748, with a
locking thread (except DBL1/DBL2) but without a fitted-keyway.
If the motors drive via pinions or toothed belts, then high radial forces will occur. The per
missible values at the end of the shaft may be read from the diagrams in chapter III. The
maximum values at rated speed you will find at the technical data. Power take-off from
the middle of the free end of the shaft allows a 10% increase in F
The curves are based on a bearing life of 20.000 operating hours.

The standard version of each motor is fitted with a thermostat (electrically isolated,
normally closed). You will find the switching point at the technical data. The thermostat
does not provide any protection against short, heavy overloading. Provided that our pre
assembled resolver cable is used, the thermostat contact is integrated into the monitoring
system of the digital servo-amplifier SERVOSTAR™ 600.
The flange temperature must not exceed 65°C in rated operation.

Motor series DBL/DBK9
General05/2001 - A.4.031.1/35Danaher Motion
I.5.6Insulation material class
The motors come up to insulation material class F according to DIN 57530.
I.5.7Vibration class
The motors are made to vibration class N according to DIN ISO 2373.
The mating connectors are not part of the delivery package. We can supply preassem
bled resolver and power leads.
In Chapter II.2.1 you will find notes on the cable materials.
I.5.9Feedback unit
The motors are equipped with two-pole hollow-shaft resolvers as standard.
As an option, the motors (except DBL1) are available with built in single- (ECN1313) or
multiturn (EQN1325) EnDat-encoders (DBL2: ECN 1113 / EQN 1125).
The motor length changes when an encoder is mounted. Retrofitting is not possible.
I.5.10Holding brake
The motors are optionally available with a holding brake (except DBL1).
A permanent magnet brake (24V DC) is integrated into the G-motors. When this brake is
de-energized it blocks the rotor. The holding brakes are designed as standstill brakes
and are not suited for repeated operational braking. If the brake is released then the rotor
can be moved without a remanent torque, the operation is free from backlash! The motor
length increases when a holding brake is mounted.
The holding brake can be controlled directly by SERVOSTAR™ 600-servo-amplifier (no
personal safety !), the winding is suppressed in the servo-amplifier — additional circuitry
is not required.
-
If the holding brake is not controlled directly by the servo-amplifier, an additional wiring
(e.g. varistor) is required. Consult our applications department beforehand.
A personal safe operation of the holding brake requires an additional contact (normally
opened) in the braking circuit and an anti-surge-device (e.g. Varistor) for the brake.

— Radial shaft-sealing rings
A radial shaft-sealing ring can be supplied at extra charge to seal against oil mist
and oil spray. This increases the protection rating of the shaft bushing to IP65. The
sealing ring is not suitable for dry running. When a holding brake is built in, the
motor length increases by a sealing ring for approximately 10mm.
— Vertical mounting sockets
If fitted with angular sockets for feedback and power connectors, the motors are
also available with vertical sockets.
— Keyway
The motors are available with keyway and key inserted according to DIN748
The shaft is balanced with a short (half) key.
— EnDat
A high resolution EnDat-encoder is mounted instead of the resolver (Þ I.5.9).
the motor length increases by the encoder.
— 2nd Thermostat
An additional thermostat can be applied to the motor winding. The connection
takes place via the power connector resp. the terminal box.
— Forced ventilation
For some motors ventilation bonnets are available wich cool the motor electrically.
Connection takes place via a 6-pole angular socket
With the ventilation bonnet mounted, the dimensions and nominal data of the
motors vary. Please consult our applications department.
All options can not be retrofitted.
I.7Selection criteria
The three-phase servomotors are designed to operate with SERVOSTAR™ 600
servo-amplifiers. Together, both units form a closed speed or torque control loop.
The most important selection criteria are:
—Standstill torqueM
—Rated speedn
—Moment of inertia of motor and loadJ[kgcm²]
—Effective torque (calculated)M
When calculating the motors and servo-amplifiers which are required, take account of the
static load and the dynamic load (acceleration/braking). Collected formulae and examples
of the calculations are available from our applications department.

II.1Important notes
Check that the servo-amplifier and motor match each other. Compare the rated
l
voltage and rated current of the unit. Carry out the wiring according to the wiring
diagram in the Installation and Commissioning Instructions for the servo-amplifier.
The connections to the motor are shown on pages 17f. Notes on the connection
methods can be found on page 16.
Ensure that there is proper earthing of the servo-amplifier and the motor.
l
Route the power and control cables as separately as possible from one another
l
(separation > 20 cm). This will improve the immunity of the system to electromag
netic interference.
If a motor power cable is used which includes integral brake control leads, then
these brake control leads must be shielded. The shielding must be connected at
both ends (see under Installation Instructions for the servo-amplifier).
Install all cables carrying a heavy current with an adequate cross-section, as per
l
EN 60204. The recommended cross-section can be found in the Technical data.
-
Caution!
If a servo-amplifier of the series SERVOSTAR™ 601 ..620 is used and the mo
tor cable exceeds 25m, a boxed choke (type 3YL-xx, manufactured by
Danaher Motion) and motor leads with the following diameters must be used:

l
and setting (observe the permissible radial and axial forces).
lCheck the wiring and connections to the motor and the servo-amplifier. Check that
the earthing is correct.
lTest the function of the holding brake, if used. (apply 24V, the brake must be re-
leased).
lCheck whether the rotor of the motor revolves freely (release the brake, if neces-
sary). Listen out for grinding noises.
lCheck that all the required measures against accidental contact with live and mov-
ing parts have been carried out.
