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 (è chapter 10 “Accessories”) in the slot 5 or 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 (è catalogue information, www.festo.com/catalogue and design
software “PositioningDrives” è www.festo.com).

 Observe the limit values for forces and positioning times

è chapter 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 (è chapter 12 “Technical data”).

The cover (è Accessories) 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

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).

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.

Fig. 5

 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

(A)

Festo handling components is made
possible through adapter plates
(è chapter 10 “Accessories”).

 Fasten the effective load to the slide

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.

Fig. 9

Protecting the end positions against
uncontrolled overrunning:

 Check whether additional hardware proximity switches are necessary

.

 Observe that this reduces the effective stroke (è catalogue specifications,

www.festo.com/catalogue).

Festo EGSL 2017-11c English

EGSL

If proximity sensors are used as hardware limit switches:

 Use proximity switches with normally-closed function.

The normally closed function protects the EGSL against overrunning the end
position if the proximity sensor cable is broken.

 Avoid external influence caused by strong magnetic fields or ferrite parts

in the vicinity of the proximity sensors. The minimum distance is summarised
in the table below:

EGSL-...

Minimum distance [mm] 20 25 20 40

Fig. 10

If proximity sensors are used as reference switches:

 Use the proximity sensors corresponding to the input of the controller used

(è catalogue specifications, www.festo.com/catalogue).

To prevent soiling:

 Use the slot covers from our catalogue.

6 Commissioning

Warning

Moving masses can cause personal injury and
material damage (crushing).

 Make sure that, in the travel range,

– nobody can place his/her hand in the

path of the moving load

(e.g.by use of a protective crate),
– there are no foreign objects.
It should not be possible to touch the EGSL
until the mass has come to a complete
standstill.

Fig. 11

Note

Incorrect default values of the braking ramp in STOP conditions
(e.g. EMERGENCY STOP and quick stop) result in overloading of the linear
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 maximum drive torque or feed force of the linear axis used is
not exceeded.

 Use the Festo “PositioningDrives” sizing software to design the mini slide

è 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 jolt-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. jolt limitation and

smoothing the acceleration profile).

Fig. 12: Definitions

Comparing the real situation
with the image in the controller

Checking the overall
behaviour

1. Start check travel limited to low dynamics.
In spite of equal control, motors of the same type sometimes turn in the
opposite direction due to the circuitry.
The EGSL has a clockwise-rotating spindle: When the drive shaft is rotated
clockwise, the slide moves in the direction of the motor.

2. Start homing in accordance with the operating instructions for your motor
drive system limited to low dynamics (max. speed: 10 mm/s):

– up to the reference switch or
– up to the retracted end position at the fixed stop.

For this, the rubber buffer aB in the slide must be removed.

3. Start a test run and limit it to low dynamic response.

4. Check whether the EGSL fulfils the following requirements:
– The slide must be able to move through the complete intended positioning

cycle.

– The slide must stop as soon as it reaches a limit switch.

5. If the proximity sensors do not respond:
è chapter 11 “Eliminating malfunctions” and the operating instructions for
the proximity switches.

7 Operation

Warning

Moveable masses can cause personal injury and material damage.
 Make sure that, in the travel range,

– nobody can place his/her hand in the path of the moving components

(e.g.by means of a protective guard),
– there are no foreign objects.
It should not be possible to touch the EGSL until the mass has come to a
complete standstill.

Festo EGSL 2017-11c English

EGSL

If the motor turns in the wrong direction:

Note

When the motor is removed
(e.g. turning the motor) the reference
position is lost.

 Start a reference run as detailed in the

chapter 6 “Commissioning”, in order to
reference the new positioning cycle.

8 Service and maintenance

Fig. 13

Warning

Controller signals can cause the EGSL to make unintented movements.
 Switch off the controller before any work on the EGSL and secure the

controller to prevent it from being switched on again.

On cleaning and maintenance:

 If necessary, clean the EGSL with a soft cloth.

Cleaning agents: Any gentle detergent

9 Disassembly and repair
