5 4 Service Contact your regional Festo contact person if you have technical questions: 5 Product overview 5.1 Function A rotating ball screw converts the rotation of a motor into straight-line motion. As a result, the slide 5 moves backwards and forwards. The slide is ball bearing guided. The reference position of the carriage can be determined using proximity sensors ( 7.4 Mounting accessories) or by referencing a fixed stop (retracted end position). 5.2 Configuration aj aa Drive hub 2 Motor mounting kit interface 3 Guide rail 4 Venting hole with filter element 5 Slide with ball bearing guide 6 Thread/centring holes for attachment components Fig. 2 7 Drill hole for accessories, at both ends (e.g.,clamping unit) 8 Thread for optional switch lug 9 Slot for sensor bracket aj Slots for mounting aa Profile housing Festo EGSC-BS-KF b English 5

6 6 Transport Note Unexpected movement of components. The mini slide is unbraked. Without input torque, the slide is freely movable. Secure slide during transport. Take product weight into account 13 Technical data. 7 Mounting 7.1 Preparation Do not modify the screws and threaded pins. Exception: immediate requirement for change in these operating instructions. Select the motor and motor attachment kit from the Festocatalogue: When using other motors, observe the limit values for forces, torques and speeds 13 Technical data. When mounting the motor: Follow the assembly instructions for the mounting attachment kit. Connect motor cables only after the mini slide is mounted. Fig. 3 Note The reference position is lost when the motor is dismantled (e.g. when turning the motor around). Start the homing procedure 8 Commissioning. Caution In case of a vertical or slanted mounting position: When de-energised, the slide can move or fall to the lower end position in an uncontrolled manner. Injury due to impacts or pinching. Bring moving parts of the product into a safe end position or secure them against falling. 6 Festo EGSC-BS-KF b English

7 Place the product in such a way that the operating elements can be reached. Install product without tension or distortion. Fasten product to a mounting surface with flatness of 0.05 % ofthe stoke length, but max. 0.5 mm. For gantry applications, attention must also be paid to parallel alignment or product heights in alignment of the axes. For additional information, contact your local Festo Service.

8 7.3 Attachment Prerequisites Note A warped attachment component bends the slide and shortens the service life of the guide. Use an attachment component with an even surface. Evenness: t = 0.01 mm Mount only to the mounting surface (B) Fig. 8. Fig. 6 Place the rated load in such a way that the break-down torque resulting from the force (parallel to the axis of motion) and the lever arm is kept as small as possible. Prevent collisions of the attachment element and the payload with other attachments Fig. 7. Fig. 7 Mounting Fasten the attachment to the slide with screws and centring sleeves. Observe the maximum screw-in depth D and tightening torque Tab. 2. For attachment components with their own guide: Precisely adjust the additional guide and mini slide or use a connection that enables a tolerance compensation. The guide isnot overloaded in this manner. (B) Fig. 8 Size Screw M3 M4 M5 M5 Max. screw-in depth D [mm] Tightening torque [Nm] Centring H7 7 Tab. 2 8 Festo EGSC-BS-KF b English

9 7.4 Mounting accessories To protect the end positions against uncontrolled excess travel: Check the necessity of proximity sensors (hardware limit switches). If proximity sensors are used as limit switches: Preferably use proximity sensors with normally closed contact function. This protects against excess travel beyond the end position, if the proximity sensor cable is broken. If proximity switches are used as reference switches: Use proximity sensors that correspond to the input of the control system being used. Mounting of the proximity sensor Use the proximity sensor with the sensor bracket (A) in the groove 9 Assembly instructions of the accessories. 9 (A) Fig. 9 Avoidance of contamination Connect sealing air. To do so, remove the filter element 4 from the housing and connect the compressed air/vacuum. 4 Fig. 10 Festo EGSC-BS-KF b English 9

10 8 Commissioning Caution Risk of injury due to unexpected movement of components. Protect the positioning range from intervention. Keep foreign objects out of the positioning range. Perform commissioning at low speed. Fig. 11 Note Incorrect set values for the braking ramp in STOP statuses (e.g. EMERGENCY OFF, QuickStop) result in an overloading of the spindle axis and can destroy it or drastically reduce its service life. Check the settings for all braking ramps in the controller or the higher-order control system (deceleration values and jerk). Set delay values (braking delay, time delays) in such a way that the maximum driving torque, acceleration or maximum feed force is not exceeded. In the process, take the following into consideration: Travel speed Moving mass Mounting position Use the Festo PositioningDrives engineering software to design the spindle axis Note Block-shaped acceleration profiles (without jerk limitation) cause high peaks in the drive force that can lead to an overloading of the drive. Due to overshooting effects, positions outside of the permissible range may also occur. A jerk-limited acceleration specification reduces vibrations in the entire system and has a positive effect on stress in the mechanical system. Check the controller settings and adapt them if necessary (e.g., jerk limitation, smoothing of the acceleration profile). 10 Festo EGSC-BS-KF b English

11 Note Axes with the same design may have different running noises due to the components used. The following factors can also influence this situation: Parameterisation Operating mode Type of mounting Installation situation (e.g, rigidity of the foundation, vibration behaviour, resonance frequencies) Procedure Purpose Note 1. Monitored run Determining the approach direction of the motor 2. Homing run Comparison of real situation to the control system mapping Even with identical control, motors of the same design can turn in opposite directions due to different wiring. Homing takes place: Against the reference switch Against an end stop Observe the maximum impact energy Tab. 4. Observe additional information Operating instructions of the drive system. 3. Test run Checking the overall behaviour Check the following requirements: The slide moves through the intended positioning cycle completely. The slide stops as soon as a limit switch is reached. After a successful test run, the slide is ready for operation.

12 9 Service Caution Unexpected movement of components. Injury due to shocks, impacts or pinching. Before working on the product, switch off the control system and secure it to prevent it from being switched back on accidentally. Check wear Regularly check the reversing backlash of the slide for spindle nut wear. The wear on the ball screw will lead to increased noise in the long term and eventually cause the ball screw to block or the spindle nut to break. The maximum permissible reversing backlash is 0.2 mm. Cleaning Clean the mini slide with a soft cloth if necessary. Do not use aggressive cleaning agents. 10 Dismounting Caution Unexpected movement of components. Injury due to shocks, impacts or pinching. Before working on the product, switch off the control system and secure it to prevent it from being switched back on accidentally. Observe information on transport 6 Transport. Remove motor cables and mounting components. 11 Disposal Dispose of the packaging and slide at the end of the production service life according to the valid provisions for environmentally sound recycling. 12 Festo EGSC-BS-KF b English

13 12 Fault clearance Malfunction Possible cause Remedy Squealing noises or vibrations and/or the mini slide runs roughly. Coupling spacing is wrong. Observe the permissible coupling distances Assembly instructions of the motor mounting kit. Tensions Install the mini slide in a tension-free manner. Observe the evenness of the bearing surface 7.1 Preparation. Resonance position of theactuator Rotational speed exceeded Controller is set incorrectly. Guide is defective or worn. Change arrangement of the tool/payload. Align the mini slide precisely parallel to the second mini slide. Change travel speed. Change parameters. Exchange the mini slide. Slide does not move. Coupling spins. Check the assembly of the motor mounting set Assembly instructions of the motor mounting set. Load levels are too high. Reduce load mass/torques. The reversing backlash is too large ( 9 Service). The no-load torque increases. Slide travels over end position. Tab. 5 Mounting screws on tool are too long. Wear Proximity sensor does not switch. Observe the maximum screw-in depth 7.3 Attachment. Exchange the mini slide. Check proximity sensor, connections and control system. Festo EGSC-BS-KF b English 13
