Performing commissioning

Running noises during operation

Identical axes can generate different running noises depending on the paramet­
erisation, mode of operation, type of mounting, installation environment and com­
ponents.

Requirement

Mounting of the drive system checked.

No foreign objects in the movement space of the propulsion system.

No mechanical overload of the axis and dynamic setpoint deviation not
exceeded (e.g. overrunning the end position) due to force and torque peaks.

Commissioning of the drive system (e.g. control and homing)

Operation

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.

Safety

WARNING!

Unexpected movement of components

Injury due to impact or crushing.

Before working on the product: secure the slide to prevent unintentional
movement.

CAUTION!

For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.

Injury due to impacts or crushing.

Bring moving parts of the product into a safe end position or secure them
against falling.

10.2

Cleaning

1. Clean the product with a soft cloth. Do not use aggressive cleaning agents.
2. If necessary, clean the guide rail with a soft lint­free cloth without detergent.

Then apply a thin layer of lubricant to the guide rail.

10.3

Lubrication

Lubrication interval and accessories

NOTICE!

The lubrication interval S

int

 is dependent on the load acting on the product.

Load factors include e. g.:

Dusty and dirty environment

Nominal stroke 

>

 2000 mm or 

<

 300 mm

Speed 

>

 2 m/s

Ambient temperature 

>

 +40 °C

Service age of product 

>

 3 years

Travel profile matches triangular operation (frequent acceleration and brak­
ing)

If one of these factors applies:

Halve lubrication interval S

int

.

If several factors apply at the same time:

Divide service interval S

int

 by four.

Malfunction

Possible cause

Remedy

Torsional stresses

Install axis without tension. Note the flat­
ness of the contact surface

è

 7.3 Fasten axis.

Change the layout of the attachment com­
ponent (e.g. payload).

Align axes parallel to one another.

Resonance oscillation
of the axis

Change the travel velocity.

Wear on guide

Contact local Festo Service.

Replace axis 

è

 www.festo.com/catalogue.

Loud running noises,
vibrations or rough
running of the axis

Insufficient lubrication
of guide

Lubricate the guide 

è

 10.3 Lubrication.

Vibrations on the slide

Operation at the reson­
ant frequency of the
axis

Change the travel velocity.

Change the acceleration.

Increase axis stiffness (e.g. shorter support
distances).

Change the payload geometry.

Long oscillations of the
profile

The resonant fre­
quency from the profile
and useful load are too
low

Increase axis stiffness (e.g. shorter support
distances).

Change the payload geometry.

Loads too high

Reduce forces and torques. Consider dynamics.

Slide does not move

Screws too long for fix­
ing the attachment
component (e.g. pay­
load)

Observe the screw­in depth

è

 7.4 Mounting the attachment component.

Overruns the end posi­
tion

Sensor does not switch

Check sensor, installation and parameterisation.
