Warning
Moving masses can cause personal injury and ma-
terial damage (risk of crushing).
• Make sure that, in the travel range,
– nobody can place his/her hand in the path
of the moving components (e.g. through a
protective guard),
– there are no foreign objects in the path of
the moving components.
It should not be possible to touch the ESBF un-
til the mass has come to a complete standstill.

Note
Incorrect set values for the braking ramp in STOP statuses
(e.g. EMERGENCY OFF, Quick Stop) result in an overloading of the spindle axis and can
destroy it or drastically reduce its service life.
• Check the settings for all braking ramps in your controller or the higher-order control
system (deceleration values and jerk).
• Taking the travel speed, moving mass and mounting position into account, make
sure that the delay values (brake delay and time delays) are set in such a way that
the maximum actuation moment or feed force of the spindle axis used is not ex-
ceeded.
• To design the spindle axis use the Festo sizing software
“PositioningDrives” ( www.festo.com).
Note
Block-shaped acceleration profiles (without jolt limitation) cause high peaks in the
motive force that can lead to an overloading of the drive. In addition, positions outside
the permissible range may occur as a result of overswing effects. A jolt-limited accelera-
tion specification reduces vibrations in the entire system and has a positive effect on
stress in the mechanical system.
• Check which closed-loop controller settings can be adapted (e.g. jerk limitation,
smoothing of the acceleration profile).
