Commissioning

Warning
Moving masses can cause personal injury or dam­
age to material items (crushing).
• Make sure that, in the positioning 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.
It should not be possible to touch the EGC until
the mass has come to a complete standstill.
Note
Incorrect specification values of the braking ramp in STOP statuses
(e.g. EMERGENCY OFF, Quick Stop) result in an overloading of the linear axis and can
destroy it or drastically reduce the 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 linear axis used is not ex­
ceeded.
• Use the "PositioningDrives" design software to design the linear axis
(è www.festo.com).
Note
Block-shaped acceleration profiles (without smoothing) cause high peaks in the drive
force that can lead to overloading of the drive. In addition, positions outside the per­
missible range may occur as a result of overswing effects. A jolt-limited acceleration
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).
Note
The elasticity of the toothed belt delays the acceleration behaviour of the EGC and res­
ults in larger accelerations than are set on the controller (spring effect).
• Take into account possible deviations from the acceleration set at the controller.
