2.12 Fundamental dangers
General
• Observe safety distances.
• Never deactivate safety devices.
• Before commissioning the product, take appropriate protective
measures to secure the danger zone.
• Disconnect power sources before installation, modification,
maintenance, or calibration. Ensure that no residual energy
remains in the system.
• If the energy supply is connected, do not move any parts by
hand.
• Do not reach into the open mechanism or movement area of
the product during operation.
2.12.1 Protection during handling and assembly
Incorrect handling and assembly
Incorrect handling and assembly may impair the product's safety
and cause serious injuries and considerable material damage.
• Have all work carried out by appropriately qualified personnel.
• For all work, secure the product against accidental operation.
• Observe the relevant accident prevention rules.
• Use suitable assembly and transport equipment and take
precautions to prevent jamming and crushing.
Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
• Stand clear of suspended loads and do not step into their
swiveling range.
• Never move loads without supervision.
• Do not leave suspended loads unattended.
2.12.2 Protection during commissioning and operation
Falling or violently ejected components

04.00 | LM | Assembly and operating manual | en | 389291
2.12.3 Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy re-
mains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its ac-
tion being dependent on the control unit and the current oper-
ating condition of the drive. Perform maintenance work, modi-
fications, and attachments outside the danger zone defined by
the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or auto-
mated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.
2.12.4 Protection against electric shock
Possible electrostatic energy
Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
• The operator must ensure that all components and assembly
groups are included in the local potential equalisation in
accordance with the applicable regulations.
• While paying attention to the actual conditions of the working
environment, the potential equalisation must be implemented
by a specialist electrician according to the applicable
regulations.
• The effectiveness of the potential equalisation must be verified
by executing regular safety measurements.

If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
•Before starting any work on the product: Switch off the power
supply and secure against restarting.
•Make sure, that no residual energy remains in the system.
WARNING
Risk of injury when the machine/system moves unexpectedly in
the case of a loss of power supply or control system
malfunction.
Use of a holding brake on the linear axis.

•A linear movement alway must reach the end position without
jerk or bounce.
•Therefore flow control valves and shock absorbers must be
used, Setting the speed [}20] and Adjustment of the shock
absorber strocke [}21].
•Please observe the diagrams and information in the catalog
pages.

2. 2 Set the damping adjustment set screw to the desired
dimension. Caution, observe the setting range!
3. Secure the set screw again.
Damping adjustment The set screw of the damping adjustment LMD (2) can be used to
adjust the stroke of the shock absorber and therefore the
absorption characteristic to the kinetic energy occurring during
operation.
To do this, loosen the counter nut and adjust the setting
dimension by turning the set screw (2).
The minimum and maximum setting dimensions for end position
adjustment can be found in the catalog.

4.4 Setting the speed
NOTICE
Risk of damage to the product!
If the end position is approached too hard, the product may be
damaged.
•Adjust exhaust throttle valve and shock absorber so that the
movement is braked smoothly.
ØClose exhaust throttle valve completely.
ØOpen exhaust throttle valve until the product starts to move.
ØContinue to open the exhaust throttle valve incrementally until
the movement decelerates smoothly.
✓If the speed is too low, the product will brake too soon and
the end position will be reached too slowly.
✓If the speed is too high, the product will impact against the
end position and the shock absorber will be overloaded.
NOTE
A smooth motion may also be too slow in many use-cases.
Further settings can be made via the shock absorbers, Adjustment
of the shock absorber strocke [}21].
