06.00 | RM-W | Assembly and Operating Manual | en | 389388
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.
2.11.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take appropriate protective measures to secure the danger
zone.
• Never step into the danger zone during operation.
2.11.3 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
remains 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
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, 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
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.

NOTICE
Material damage due to pressure loss!
On delivery, the lock nuts for end position and absorber
adjustment are only hand-tightened. This could lead to a loss in
pressure and cause considerable material damage.
•Tighten the lock nuts for end position and shock absorber
adjustment before commissioning.
NOTICE
Material damage due to improper assembly!
•When mounting loads, do not allow impermissible forces and
moments to be exerted (see catalog data sheet).
•Select a suitable tightening torque when assembling the
product or loads on the product in accordance with the
generally accepted guidelines for screw connections.
•Secure all screws using a suitable chemical screw lock.

• Shock absorber (22)
• Counter nut (23)
Angle of rotation fine
adjustment
ØRelease counter nut (10).
ØBy twisting the stop coupling (13) with the rod (14) and shock
absorber (22) that are integrated in it, the angle of rotation in
both end positions can be set by ±5° from the nominal angle of
rotation. The nominal rotation angle has to be specified for the
order and can be selected without steps between 5° and 180°.
Standard angles are 90° and 180°.
ØTighten the stop coupling again with the counter nut.
Damping adjustment
NOTICE
Use the shock absorber!
Operation without the shock absorber included within the scope
of delivery is not permitted.
•Observe the maximum mass moment of inertia (☞ catalog
data).
•Adjust the dampening at the mass moment of inertia.
■The desired angle of rotation has been set.
ØRelease counter nut (23).
ØBy turning the shock absorber (22) in and out, the stroke of the
shock absorber (and therefore the shock absorber characteristic
curve) can be adjusted to the mass moment of inertia occurring
in operation. The previously adjusted angle of rotation is not
influenced by this.
