Warning
Moving masses can cause personal injury or
material damage (crushing).
S Within the positioning range, make sure
that
nobody can place his/her hand in the path
of the moving parts (e. g. by means of
a protective guard),
there are no foreign objects present.
It should not be possible to touch the DMES
until the mass has come to a complete
standstill.
Note
Incorrect default values of the braking ramp in STOP statuses (e. g. EMER
GENCY STOP and quick stop) result in overloading of the linear axis and can
damage it or drastically reduce its service life.
S Check the settings for all braking ramps in your controller or the higher−order
control system (delay values and jerk).
S Taking the travel speed, moving mass and mounting position into account,
make sure that the delay values (brake delay, time delays) are set in such a
way that the maximum driving torque or feed force of the linear axis being
used is not exceeded.
S Use the Festo PositioningDrives" sizing software to dimension the linear axis

Note
Block−shaped acceleration profiles (without jerk limitation) cause high peaks in
the motive force, which can lead to overloading of the drive. In addition, posi
tions outside the permissible range may occur as a result of overshoot effects.
A jerk−limited acceleration specification reduces the vibrations in the entire
system and has a positive effect on the stress in the mechanical system.
S Check which controller settings may be adapted (e. g. jerk limitation,
smoothing of the acceleration profile).
