Tab. 5 Information on attachment components
7.6 Fasten accessories
Requirement
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
– Protection against uncontrolled overtravel of the end positions.
– Homing to reference switch or end position.
– Query of end positions or intermediate positions.
– Avoidance of hard impacts at the end positions.
– Prevention of contamination in the slots.
1. Select accessories è www.festo.com/catalogue.
2. Mount mechanical end position protection:
– Mount shock absorber retainer.
– Mount shock absorber or emergency buffer.
3. Mount the sensor (reference or query):
– Mount the sensor bracket and switch lug (depending on the type of
mounting).
– Mount the sensor.
– Fasten the cable with clips.
4. Mount the slot cover.

(not ELGA­TB­...­F1) (only ELGA­TB­...­F1)
– Mounting via profile
groove – Switch lug: mounting on
slide
– Sensor bracket: mounting
via profile groove
For axes with ELGA­TB­M1/M2
measuring system, mounting is
only possible on the side
without measuring system.
– Switch lug: mounting on
slide
– Mounting kit: mounting
via profile groove
– Protect the sensor from external magnetic or ferritic influences (e.g . min. 10 mm distance to
slot nuts).
– Preferably use hardware limit switches with normally closed function (protection guaranteed
even in case of sensor failure).
– Query switch lug only with inductive sensor (not ELGA­TB­...­F1).
– Mounting the measuring system.

Connecting sealing air
The use of sealing air reduces or prevents subsequent contamination:
–
The application of negative pressure minimises the release of abraded
particles into the environment.
– Applying overpressure reduces the penetration of dirt into the drive train.
Fig. 5 Remove the plug screw
1. Remove the sealing air plug screw from the threaded hole.
2. Mount the screw fitting and connect the hose.

8.1 Safety
WARNING!
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.
8.2 Performing commissioning
Performing commissioning
NOTICE!
Elasticity of the toothed belt
The elasticity of the toothed belt generates an additional spring effect at high
acceleration and deceleration, which can lead to an inadmissible nominal/actual
deviation when the slide is moved or when the end position is reached.
•
Consider the setpoint deviation determined during the test run during para­
meterisation of position setpoint values.
When the motor is removed, the motor encoder loses its absolute reference to the
reference mark (e.g. by turning the motor drive shaft).
•
Carry out a homing run after every motor mounting in order to establish the
absolute reference between the motor encoder and the reference mark.
High noise emission
Identically constructed axes can generate different running noises depending on
the parameterisation, mode of operation, type of mounting, installation environ­
ment and components.
Requirement
–
Mounting of the drive system checked.
– The protective cover of the cover strip is removed.
– Installation and wiring of the motor checked.
– No foreign objects in the movement space of the propulsion system.
– No exceeding of the max. permissible feed force and drive torque as a func­
tion of acceleration, deceleration (e. g. stop function, quick stop), velocity,
moving mass and mounting position.
– No mechanical overload of the axis and dynamic setpoint deviation not
exceeded (e. g. overrunning the end position) due to force and torque peaks
or overshoot effects.
Limit overloads and overruns by jerk limitation, lower acceleration and decel­
eration setpoints or optimised controller settings.
– Control and homing travel at reduced velocity, acceleration and deceleration
setpoints.
– No test drive to mechanical end stops.
Proced-
ure Purpose Note
1. Check
run Determining the direction of travel
of the slide – The direction of movement of the slide for
positive and negative position values
depends on the mounting position of the
motor on the axis.
– Adapt a required reversal of direction of
rotation via parameters in the servo drive or
in the controller.
2. Homing Determination of the reference
point and adjustment of the dimen­
sional reference system
–
during the initial start­up pro­
cedure
– after replacement of the motor
Permissible reference points:
–
towards reference switch.

drive system, www.festo.com/sp.
3. Test run Checking the operating conditions Check application requirements:
–
Slide travels through the complete travel
cycle in the specified time.
– Slide stops moving when a limit switch is
reached.
After a successful test run, the drive system is ready for operation.

10.1 Safety
WARNING!
Unexpected movement of components.
Injury due to impacts or crushing.
•
Before working on the product, switch off the control and secure it to prevent
it from being switched back on accidentally.
