5 Product overview
5.1 Function
The slide of the axis follows the movement of the parallel mounted drive axis via
the mechanical coupling. The linear movement of the slide is precisely guided by
the guide. Sensors enable the monitoring of end positions, reference position and
intermediate position.

7 Assembly
7.1 Safety
WARNING!
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
7.2 Unpack product
1. Open packaging.
2. Remove all transport materials (e.g.foils, caps, cardboard boxes)
3. Remove the product from the packaging and place it on the mounting surface.
Comply with maximum permitted support clearances when attaching trans
portation aids è 14.2 Characteristic curves.
4. Dispose of packaging and transport materials è 13 Disposal.
7.3 Fasten axis
High mechanical loads on the mounting connections
If high parallel torques are applied to the drive system at the same time, this
leads to high mechanical loads at the mounting interfaces.
• The foot mountingHPE should only be used in combination with the profile
mountingMUE or the slot nutsNST.
Requirement
– No collision in the movement space of the attachment component with
mounting and sensor components.
– Sufficient space to reach maintenance interfaces.
– Flatness of the mounting surface of 0.05%of the stroke length or max.
0.5mm over the stroke length of the bearing surface.
– Required support points lie within the specified support
distancesè 14.2 Characteristic curves.
– No distortion or bending when installing the product.
1. Select mounting attachments èwww.festo.com/catalogue.
2. Place the mounting attachments on the support points.

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
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) èInstruction
manual for drive axis, www.festo.com/sp.

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 lintfree 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 Sint 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 Sint.
If several factors apply at the same time:
• Divide service interval Sint by four.
