4 Service
Contact your regional Festo contact person if you have technical questions:

5 Product overview
5.1 Function
A rotating ball screw converts the rotation of a motor into straight-line motion. As a result, the slide 5
moves backwards and forwards. The slide is ball bearing guided. The reference position of the carriage
can be determined using proximity sensors (è7.4 Mounting accessories) or by referencing a fixed stop
(retracted end position).

6 Transport
Note
Unexpected movement of components. The mini slide is unbraked. Without input
torque, the slide is freely movable.
 Secure slide during transport.
 Take product weight into account è13 Technical data.
7 Mounting
7.1 Preparation
 Do not modify the screws and threaded pins.
Exception: immediate requirement for change in these operating instructions.
 Select the motor and motor attachment kit from the
Festocatalogue: èwww.festo.com/catalogue.
When using other motors, observe the limit values for forces,
torques and speeds è13 Technical data.
 When mounting the motor: Follow the assembly instructions for
the mounting attachment kit.
 Connect motor cables only after the mini slide is mounted.
Fig. 3
Note
The reference position is lost when the motor is dismantled (e.g. when turning the
motor around).
 Start the homing procedure è8 Commissioning.
Caution
In case of a vertical or slanted mounting position:
When de-energised, the slide can move or fall to the lower end position in an
uncontrolled manner. Injury due to impacts or pinching.
 Bring moving parts of the product into a safe end position or secure them against falling.

EGSC-BS-KF

 Place the product in such a way that the operating elements can
be reached.
 Install product without tension or distortion.
 Fasten product to a mounting surface with flatness of 0.05 %
ofthe stoke length, but max. 0.5 mm.
For gantry applications, attention must also be paid to parallel
alignment or product heights in alignment of the axes.
For additional information, contact your local Festo Service.

7.3 Attachment
Prerequisites
Note
A warped attachment component bends the slide
and shortens the service life of the guide.
 Use an attachment component with an even
surface.
Evenness: t = 0.01 mm
 Mount only to the mounting surface (B) èFig. 8.
Fig. 6
 Place the rated load in such a way that the break-down torque
resulting from the force (parallel to the axis of motion) and the
lever arm is kept as small as possible.
 Prevent collisions of the attachment element and the payload
with other attachments èFig. 7. Fig. 7
Mounting
 Fasten the attachment to the slide with screws and centring
sleeves. Observe the maximum screw-in depth D and tightening
torque èTab. 2 .
For attachment components with their own guide:
 Precisely adjust the additional guide and mini slide or use a
connection that enables a tolerance compensation. The guide
isnot overloaded in this manner.

7.4 Mounting accessories
To protect the end positions against uncontrolled excess travel:
 Check the necessity of proximity sensors (hardware limit switches).
If proximity sensors are used as limit switches:
 Preferably use proximity sensors with normally closed contact function.
This protects against excess travel beyond the end position, if the proximity sensor cable is broken.
If proximity switches are used as reference switches:
 Use proximity sensors that correspond to the input of the control system being used.
Mounting of the proximity sensor
 Use the proximity sensor with the sensor bracket (A) in the
groove 9 èAssembly instructions of the accessories.

Avoidance of contamination
 Connect sealing air. To do so, remove the filter element 4from
the housing and connect the compressed air/vacuum.

8 Commissioning
Caution
Risk of injury due to unexpected movement of
components.
 Protect the positioning range from intervention.
 Keep foreign objects out of the positioning
range.
 Perform commissioning at low speed.
Fig. 11
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 the controller or the higher-order control
system (deceleration values and jerk).
 Set delay values (braking delay, time delays) in such a way that the maximum driving
torque, acceleration or maximum feed force is not exceeded. In the process, take
the following into consideration:
– Travel speed
– Moving mass
– Mounting position
 Use the Festo “PositioningDrives” engineering software to design the spindle axis
èwww.festo.com.
Note
Block-shaped acceleration profiles (without jerk limitation) cause high peaks in the
drive force that can lead to an overloading of the drive. Due to overshooting effects,
positions outside of the permissible range may also occur. A jerk-limited acceleration
specification reduces vibrations in the entire system and has a positive effect on stress
in the mechanical system.
 Check the controller settings and adapt them if necessary (e.g., jerk limitation,
smoothing of the acceleration profile).
