2 Function and application
A rotating slide spindle converts a motor’s rotation into linear motion. The slide 3
will then move backwards and forwards. The slide is bearing mounted. The
reference position of the slide unit can be determined with the help of proximity
sensors (èchapter 10 “Accessories”) in the slot 5or through homing against a
fixed stop (retracted end position).
The EGSL mini slide is intended to be used for the precise positioning of effective
loads.
Note
The EGSL mini slide does not have automatic locking: When input torque is not
applied, the slide can be moved freely.
A latching function for the entire system can usually be achieved by the use of
motors with an integrated holding brake or by other suitable measures such as,
for example, clamping systems, motors with high gear ratios or automatically
locking gear units. Which measure is appropriate to select basically depends on
the application and the safety requirements.
 Select the corresponding Festo motor from our catalogue.
You will then be operating mating devices, which are especially adapted to
each other (ècatalogue information, www.festo.com/catalogue and design
software “PositioningDrives” èwww.festo.com).
 Observe the limit values for forces and positioning times
èchapter 12 “Technical data”.
3 Transport and storage
 Take the product’s weight into account. It weights up to 8 kg.
 Ensure the following storage conditions are met:
– short storage times
– cool, dry, shaded, corrosion-resistant storage locations.

4 Requirements for product use
Warning
Unexpectedly fast moveable masses can harm people or property (crushing).
 Apply power to the drive motor, at first limited to low speeds and torques.
Note
Particles (e.g. dust, liquids, ...) which penetrate the mechanics of the EGSL can
cause damage or lead to reduced performance.
 Make sure that the dust concentrations for the permitted IP protection class
are complied with (èchapter 12 “Technical data”).
The cover (èAccessories) prevents reaching between guide rail and end
cover, but not penetration of dust and contamination.
Note
Malfunctions will occur if the device is not used correctly.
 Be sure to always comply with the specifications in this chapter. In this way,
the product will perform as intended.
 Compare the limit values specified in these operating instructions with those
of your actual application (e.g.forces, torques, temperatures, masses, speeds).
Only compliance with the load limits allows operation of the product in
compliance with the relevant safety regulations.
 Take into consideration the ambient conditions at the location of use.
Corrosive elements in the environment (e.g.ozone) will reduce the service life of
the product.
 Comply with the regulations of the trade association, the German Technical
Control Board (TÜV) or corresponding national regulations.
 Remove transport packaging such as films and cardboard.
The packaging is intended to be recycled on the basis of its constituent
materials (exception: oiled paper = other waste).
 Use the product in its original condition without any unauthorised
modifications.

EGSL
Festo EGSL 2017-11c English 7
 Note the warnings and instructions on the product and in the relevant
operating instructions.
 Take the tolerance of the tightening torques into account. Unless otherwise
specified, the tolerance is ±20 %.
5 Installation
Mechanical installation
 Do not modify the screws and threaded
pins if not directly requested to do so in
these operating instructions.
 Mount the motor on the mini slide in
accordance with the assembly
instructions for the motor mounting kit
recommended in the catalogue.
For installation in a vertical or sloping position:
Warning
Falling masses can cause personal injury
and material damage (crushing).
If there is a power failure or if the spindle
nut breaks, the work mass will drop.
 Make sure that you use only motors
with an integrated holding brake.
 Check whether additional external
safety measures are required to
prevent damage due to spindle nut
fracture (e.g.toothed latches or
moving bolts).
 Make sure that the device is installed free of mechanical stress and sag
(evenness of bearing surface ≤0.05 % of stroke length).
 Position the EGSL so that its control sections can be reached.

Installing the effective load
Note
If the steel slide becomes bent against a
buckled effective load, the service life of the
guide will be reduced.
 Make sure that the mounting surface of
the effective load is even to within
t ≤ 0.05 mm.
 Place the effective load so that the pull-out torque from the force
(parallel to the axis of motion) and lever arm remains low.
 Check the necessity of adapter plates.
Connection of the EGSL to
Festo handling components is made
possible through adapter plates
(èchapter 10 “Accessories”).
 Fasten the effective load to the slide
unit with screws (A) and, if necessary,
with centring elements (B).
The screw-in depth must be less
than the threaded holes.

For useful load geometries with projection in
the longitudinal direction of the slide:
 Make sure that the useful load does not
strike against the motor.
Electrical installation
If proximity sensors are used:
 Push the proximity sensors through the
cut-out aC on the housing cover into the
upper sensor slot.
The cable of a proximity sensor can be
guided away via the cross groove (C) into
the lower groove.
Protecting the end positions against
uncontrolled overrunning:
 Check whether additional hardware proximity switches are necessary.
 Observe that this reduces the effective stroke (ècatalogue specifications,
www.festo.com/catalogue).
