Incorrect set values for the braking ramp during STOP conditions (e.g. emergency stop, quick stop) result in overload-
ing of the toothed belt axis and can destroy it or dramatically reduce its service life.
– Check the settings for all braking ramps in your controller or the higher-order control system (deceleration values
and jerk).
– Make sure that the deceleration values (braking deceleration, deceleration times) for the speed, the load to be
moved and the mounting position (horizontal/vertical) as well as the specified maximum driving torque or the
feed force correspond to the permissible values for the toothed belt axis used.
– Use the Festo “Positioning Drives” sizing software, available via the Festo website ( www.Festo.com ).
• Ambient conditions/material resistance
Check whether the ambient temperature is within the permissible range.
Check the chemical and physical ambient conditions for hazardous substances such as dust, abrasive particles, cool-
ing lubricants, solvents, ozone, radiation, water-soluble greases and oils, etc.
4.1.1 Replacing the toothed belt
Note
This description presupposes that the toothed belt is not torn or that the
tear is located in the visible area. The drive covers must be removed if the
tear is located in the drive covers or the cylinder barrel (see section
4.2.1
“Removing the drive covers” ).
Do not pull the old toothed belt out of the axis before you have joined it to
the new toothed belt, as otherwise you will also need to remove the drive
covers.
• Place the toothed belt axis on the work surface as shown with the slide
facing upwards.
• Lever off the cover caps at both ends from the drive covers.
Note
The screw heads of the socket head screws are filled with locking paint. You
can ensure a secure fit for the Allen key by carefully tapping it into the screw
head using a hammer.
• Loosen the socket head screw in the clamping bodies and unscrew it.
• Move the slide to the left and right to release the clamping bodies from the
slide.
