WARNING
Risk of severe burns due to hot surfaces on the linear motor!
During the operation of the system the surface temperature of the linear motors can reach ≥ 50°C. There is
an acute risk of sustaining burns to parts of the body and limbs.
Take the following measures to avert danger:
• Do not touch any components (housing, etc.) shortly after or during operation.
• Wait until all components have cooled sufficiently. At least 15 minutes.
• Check the surface temperature with a thermometer.
•DO NOT wear work gloves with a rubber coating. These can fuse with the skin on account of the high
temperature and cause serious injuries.
Notes on the operation of the AL2xxx linear motors:
• Read this manual carefully and completely before using the linear motor. Notify the responsible
sales office immediately if any passages are not understandable. Do not work on the linear mo-
tor.
• Adhere without fail to the climatic conditions for the installation. Further information can be found
in the Technical data [}46] and Mechanical installation [}20] sections.
NOTE
High temperatures can damage the magnets!
Do not expose the magnets to temperatures ≥ 70°C. This can lead to demagnetization.
Deadly danger due to the magnetic fields of the linear motor!
The AL2xxx linear motors are equipped with permanent magnets in the magnetic plate. Strong
magnetic fields are present here. In the power-off state, the magnetic field strength of the motors re-
sults exclusively from the magnetic fields of the secondary part.
There is a particular danger for:
people fitted with cardiac pacemakers
(The cardiac pacemaker can be switched to test mode and thus cause a cardiac arrest!)
People with implanted defibrillators
(The defibrillators can be rendered inoperative by the magnetic field!)
NOTE
Loss of data due to magnetic fields!
-- Magnetic data storage devices
-- Chip cards with magnetic strips and
-- Electronic devices can be demagnetized by magnetic fields.
There is a risk of the loss of data.
The objects listed above and loose-lying ferromagnetic objects may not be brought any closer than 1 m to
the magnetic plates.
The requirements in BGV B 11 applying to magnetic fields and the national regulations applicable in other
countries must be observed.

For your safety
AL200012 Version: 6.3
CAUTION

4 Handling
4.1 Transport
NOTE
Short-circuit due to moisture in the AL2xxx linear motors!
Condensation may form when transporting in cold weather or in the case of extreme temperature differ-
ences:
• Make sure that no moisture condenses inside the linear motor packaging (bedewing). Equalize the room
temperature slowly. Only switch the linear motor on when it is completely dry.
Despite the sturdy construction, the components are sensitive to strong vibrations and impacts.
During transport, protect the product against:
• high mechanical stress
• large temperature fluctuations (max. 20 K/hour)
• excessively high humidity (max. relative humidity 95%, non-condensing)
For the dispatch, use proper packaging that meets the requirements specified in this chapter for the transport
of the linear motors. This could also be the manufacturer's original packaging.
Since linear motors contain electrostatically sensitive components that can be damaged by improper
treatment:
• Avoid electrostatic charging before you touch the device or components directly.
• Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
• Place the servo drive on a conductive surface.
• If the packaging is damaged, inspect the linear motor and any accessories for visible damage. Inform

6 Technical description
6.1 Design of the motors
The linear servomotors from the AL2xxx series are brushless three-phase motors for high-quality servo
applications. In conjunction with our digital servo drives they are particularly suitable for positioning tasks in
industrial robots, machine tools, transfer lines, handling equipment, textile machines, packaging machines,
etc. with high requirements for dynamics and stability. The motors from the AL2xxx series are intended to be
operated exclusively by a digital servo drive with speed and torque control.
The linear servomotors are equipped with permanent magnets in the magnetic plate. This advanced
neodymium magnetic material makes a significant contribution to the motors' exceptional dynamic
properties. A three-phase coil unit supplied by the servo drive is housed in the coil unit. The motor has no
brushes; the commutation being implemented electronically in the servo drive.
Furthermore, a feedback system is necessary for operation. The suitable feedback system must be selected
on the basis of the application requirements. Dynamics, speed, contamination levels, resolution and the
servo drive must be considered (see also the section entitled Magnetic Encoder System (MES) (optional)
[}18]).

6.3 Standard features
Machine concept
The AL2xxx linear servomotor series from Beckhoff is not a self-contained
system. It includes various components such as a coil unit and magnetic plates
and must be integrated into a complete machine concept or a complete working
unit.
The size and shape of the carrier frame, the design of the carriage, the type of
rail and type of bearings, and the kind of buffer used depend on the application.
The carrier frame and the carriage must be designed such that an air gap is
created between the coil unit and the magnetic plate.
6.3.1 Coil unit, primary part (N/S)
Winding types
The N-type (normal winding) represents the preferred type. The S-
type (speed winding) has a higher maximum speed and a higher
current consumption. The dimensions of the N-type and S-type do not
differ.
6.3.2 Magnetic plate, secondary part
Magnetic plates are available in various lengths and can be combined with one another as desired within a
series. Different series require magnetic plates with different widths.
Magnetic plate without transport plate Magnetic plate with transport plate
In the delivery condition the magnetic plates are covered by a transport plate. It reduces the magnetic field
and thus enables simple mounting and dismounting.
Specifications and dimensional drawings can be found in the chapter: Technical data [}46]

Technical description
AL200018 Version: 6.3
6.3.3 Magnetic Encoder System (MES) (optional)
The Magnetic Encoder System (MES) AL2200-000y is a position measuring system. It has an accuracy of
0.1 mm and works directly on the magnetic plates. There are no further measuring scales. Fastening takes
place on the carriage.
Description of the position measuring system
The MES works absolute within the pole distance (24 mm) and semi-absolute over the entire track. The
distance to the coil part is not relevant. The commutation angle is determined once during commissioning.
The wake & shake at the start of the machine is thus dispensed with. Homing can be carried out if an
absolute synchronization is desired.
Documentation for the Magnetic Encoder System (MES)!
Further information on the Magnetic Encoder System (MES) can be found on the Beckhoff home-
page under: MES Feedback Documentation or in the Beckhoff Online Information System.
6.4 Additional equipment
You require further components for the proper installation of your linear servomotor.
These are not included in the scope of delivery.
Screws and locating pins
The screws and locating pins are needed to position and fasten the coil
unit to the carriage, and also the magnetic plates to the carrier frame.

7.1 Important notes
Installation of the machine bed must be complete before installing the linear motor components. The rails
must be mounted on the machine bed and aligned. The carriage must be equipped with bearings, dampers
and the required lines so that the proper movement of the carriage over the track is ensured.
WARNING
Damage due to uncontrolled magnetic attractive forces
The sequence specified in this introduction for the installation must be followed. A different sequence can
give rise to dangerous situations, and can lead to damage resulting from uncontrolled magnetic attraction.
Damage due to faulty water cooling unit
If a water cooling unit is to be used, read please the section entitled Installation of the water cooling
[}40].
Deadly danger due to the magnetic fields of the linear motor!
The AL2xxx linear motors are equipped with permanent magnets in the magnetic plate. Strong
magnetic fields are present here. In the power-off state, the magnetic field strength of the motors re-
sults exclusively from the magnetic fields of the secondary part.
There is a particular danger for:
people fitted with cardiac pacemakers
(The cardiac pacemaker can be switched to test mode and thus cause a cardiac arrest!)
People with implanted defibrillators
(The defibrillators can be rendered inoperative by the magnetic field!)
NOTE
Loss of data due to magnetic fields!
-- Magnetic data storage devices
-- Chip cards with magnetic strips and
-- Electronic devices can be demagnetized by magnetic fields.
There is a risk of the loss of data.
The objects listed above and loose-lying ferromagnetic objects may not be brought any closer than 1 m to
the magnetic plates.
The requirements in BGV B 11 applying to magnetic fields and the national regulations applicable in other
countries must be observed.
CAUTION
Damage due to a magnetic field that is not neutralized
Use the magnetic plates only when they are covered by the protective plates that reduce the magnetic field.
CAUTION
Damage during dismantling due to the magnetic field
Make sure that the magnetic plates are fastened in your machine before removing the protective plates.
Put the protective plates back onto the magnetic plates before dismantling them.
Do not bring any soft-magnetic objects (iron) closer than 10 cm to the magnetic side of the magnetic plates.
