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.

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.

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. 9 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. 10 Maintenance 10.1 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 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.

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. 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. 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. Tab. 9 Overview of fault clearance
