For your safety
Version: 2.2 ─── 13AS2000
Read this chapter containing general safety information. The chap-
ters in these operating instructions also contain warning notices. Al-
ways observe the safety instructions for your own safety, the safety
of other persons and the safety of the product.
When working with control and automation products, many dangers
can result from careless or incorrect use. Work particularly thor-
oughly, not under time pressure and responsibly towards other peo-
ple.
2.1Safety pictograms
On Beckhoff products you will find attached or lasered safety pic-
tograms, which vary depending on the product. They serve to pro-
tect people and to prevent damage to the products. Safety pic-
tograms must not be removed and must be legible for the user.
Warning of a hot surface
During and after operation there is a risk of burns at the motor hous-
ing due to hot surfaces over 60°C. Allow the motor housing to cool
down for the specified time, at least 15 minutes.
Avoid shocks to the shaft
on the shaft may cause the maximum permissible axial and radial
values to be exceeded. Optical encoder systems can thus be de-
stroyed.

For your safety
14 ─── Version: 2.2AS2000
2.2General safety instruc-
tions
In this chapter you will find notes on safety when handling the mo-
tors. They cannot run independently. The motors are therefore re-
garded as incomplete machines. They must be installed in a ma-
chine / plant by the machine manufacturer. The documentation cre-
ated by the machine manufacturer must be read.
2.2.1Before operation
Protective equipment
Do not remove or bypass any protective devices. Check all protec-
tive devices before operation. Make sure that all emergency
switches are present at all times and can be reached by you and
other people. People could be seriously or fatally injured by unpro-
tected machine parts.
Shut down and secure the machine or plant
Shut down the machine or plant. Secure the machine or plant
against being inadvertently started up.
Correctly ground electrical components or modules
Avoid electric shocks due to improper grounding of electrical compo-
nents or modules. Ground all conductive components according to
the specifications in the chapters "Electrical Installation" and "Me-
chanical Installation".
Keep the immediate environment clean
Keep your workplace and the surrounding area clean. Ensure safe
working.
Check safety pictograms
Check whether the designated pictograms are on the product. Re-
place missing or illegible stickers.
Observe tightening torques
Mount and repeatedly check connections and components, comply-
ing with the prescribed tightening torques.
Use the original packaging only
When shipping, transporting, storing and packing, use the original
packaging or conductive materials.

For your safety
Version: 2.2 ─── 15AS2000
2.2.2During operation
Do not work on live electrical parts
Do not open the motor while it is live. Ensure that the protective con-
ductor is connected properly. Never loosen electrical connections
when live. Only work on the motor when the voltage has dropped to
<50V. Disconnect all components from the mains and secure them
against being switched on again.
Do not touch hot surfaces
Check the cooling of the surfaces with a thermometer. Do not touch
the components during and immediately after operation. Allow the
components to cool sufficiently after switching off.
Avoid overheating
Operate the motor according to the technical specifications. Please
refer to chapter: "Technical data". Activate and monitor the tempera-
ture contact of the motor. Provide for sufficient cooling. Switch the
components off immediately if the temperature is too high.
Do not touch any moving or rotating components
Do not touch any moving or rotating components. Fasten all parts or
components on the machine or plant.
2.2.3After operation
De-energize and switch off components before working on
them
Check the functionality of all safety-relevant devices. Secure the
working environment. Secure the machine or plant against being in-
advertently started up. See chapter: "Decommissioning"

3.3Product characteristics
Standardized NEMA flange sizes
Adaptation to international standards through flange sizes N2,
NEMA23 and N3, NEMA34.
Step angle and power range
The power gap to the AM8000 synchronous servomotor is consider-
ably reduced through a step angle of 1.8°.
High protection class
The IP54 protection class protects the stepper motors against
splash water, contact and dust.
Extended features
• Integrated M12 power connector and feedback socket
• Integrated torsion-proof encoder, 1024 inc/rev, for closed-loop
control
By means of the field-oriented control, resonances are significantly
decreased and the development of heat and noise on the motor is
reduced.
Stepper motor terminals and stepper motor modules
All motors from the AS2000 series are to be put into operation with
Beckhoff motor terminals and modules for stepper motors. For fur-
ther details at chapter "Electrical installation", [Page61].

3.5Intended use
Beckhoff stepper motors from the AS2000 series are specially de-
signed for use as actuators in handling devices, textile machines,
machine tools, packaging machines and similar machines. They are
intended to be controlled and operated in terms of speed and posi-
tion by Beckhoff stepper motor output stages.
The stepper motors from the AS2000 series may be operated exclu-
sively for the activities foreseen and defined in this documentation,
taking into account the prescribed environmental conditions.
The components are to be installed in electrical systems or ma-
chines and only put into operation as integrated components of the
system or machine.
