Commissioning

Warning
Moving masses can cause personal injury and
material damage (crushing).
• Make sure that, in the positioning range,
– nobody can place his/her hand in the path
of moving components (e.g. by providing a
protective screen),
– there are no foreign objects.
It should not be possible to touch the DNCE
until the mass has come to a complete
standstill.
Note
Incorrect default values of the braking ramp in STOP conditions
(e. g. EMERGENCY STOP, Quick Stop) result in overloading of the spindle axis and can
damage it or drastically reduce its service life.
• Check the settings for all braking ramps on your controller or the higher-order
controller (deceleration values and jerking).
• Taking the travel speed, moveable load and mounting position into account, make
sure that the delay values (brake delay and delay times) are set in such a way that
the max. drive torque or max. feed force of the spindle axis used is not exceeded.
• Use the "PositioningDrives" sizing software to design the spindle axis
( www.festo.com).
Note
Block-step acceleration profiles (without smoothing) cause high peaks in the motive
force that can lead to drive overload. In addition, positions outside the permissible
range may occur as a result of overswing effects. A jerk-limited acceleration
specification reduces vibrations in the entire system and has a positive effect on stress
in the mechanical system.
• Check which controller settings may be adapted (e.g. jerk limitation and smoothing
of the acceleration profile).
