4.2 Function
The axis converts the rotary motion of the mounted motor into a linear motion of the slide. The
screw drive converts the torque of the motor into a feed force. The linear movement of the slide is
precisely guided by the guide. Sensors enable the monitoring of end positions, reference position and
intermediate position.
5 Transport
WARNING
Risk of injury due to falling product
If the product is lifted incorrectly, it may fall and cut, crush or separate body parts.
• Lift the product only with suitable load-bearing equipment.
–Store and transport the product in its original packaging. Observe the weight, the dimensions and
the ambient conditions.
–Take the centre of gravity of the product into consideration.

Tab. 2: Overview of mounting components
Requirements:
–Adequate clearance for payload to avoid collisions with motor, mounting components and sensor
components.
–Sufficient space for maintenance work.
–Flatness of the mounting surface of 0.05%of the stroke length or maximum 0.5mm over the stroke
length of the bearing surface.
–Required support points lie within the specified support clearances è10.2 Characteristic curves
of support distances. Compliance with the support clearances prevents the axis from excessive
bending.
1. Place the mounting components on the support points.
2. Tighten the screws. Observe the maximum tightening torque and maximum screw-in depth.
When used in multi-axis systems: align to the first axis and install without tension.

Requirements:
–Protect the sensor from external magnetic or ferritic influences with min. 10 mm distance from slot
nuts.
–Use a hardware limit switch with N/C contact function to guarantee protection in the event of a
sensor failure.
1. If necessary, mount the switch lug.
2. If necessary, mount the sensor bracket.
3. Mount the sensor.
7 Commissioning
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.
Festo — ELGT-BS — 2023-07a

Block-shaped acceleration profiles without jerk limitation can have the following effects:
• High mechanical loads on the lead screw due to high force peaks.
• Overshooting effects during positioning.
• Rise of the entire system.
Recommendation: reduce high force peaks in the acceleration and deceleration phases by using the
jerk limitation.
Identical axes can generate different running noises depending on the parameterisation, mode of
operation, type of mounting, installation environment and components.
For use with reduced particle emission:
• Clean product è8.3 Cleaning axis.
Requirements:
–The motor encoder is referenced to the reference mark by a homing run.
–The motor encoder has the absolute reference to the reference mark.
–The direction of movement of the slide is determined by the direction of rotation of the motor.
–The mounting of the drive system has been checked.
–The installation on the motor has been checked.
–There are no foreign objects within the range of motion of the drive system.
–Maximum permissible feed force and drive torque as a function of acceleration, deceleration,
e.g.with stop function or quick stop, speed, moving mass and mounting position, are not exceeded.
–Axis is not mechanically overloaded and dynamic setpoint deviation is not exceeded as a result of
force peaks, torque peaks or overshoot effects, e.g.overrunning the end position.
Overloads and overruns as a result of jerk limitation must be restricted by reduced acceleration and
deceleration setpoints or optimised controller settings.
–The software end positions are not within the effective range of the mechanical stops.
–No homing or test run to mechanical end stops.
1. Start check run.
2. Select permissible reference points "against reference switch" for the homing.
3. Start the homing run with reduced speed setpoints, acceleration setpoints and deceleration
setpoints.
4. Start the test run with reduced speed setpoints, acceleration setpoints and deceleration set-
points.
5. Check that the slide completes the entire travel cycle within the specified time.
ÄThe slide stops its travel when it reaches a limit switch and the drive system is ready for
operation.

8.1 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.
8.2 Check reversing backlash
• Check the reversing backlash (reversal error) of the slide at every maintenance interval, e.g.lubri-
cation interval. If the maximum permissible reversing backlash is exceeded, replace the axis.

8.3 Cleaning axis
–If the guide rail is dirty, clean it with a clean, soft and lint-free cloth without cleaning agents and
then apply the lubricant thinly to the guide rail.
–Clean the other product components with a clean, soft cloth and non-abrasive cleaning agents.
For use with reduced particle emission:
–Remove abraded particles and dirt from the product:
–Prior to initial commissioning.
–Regularly during operation.
8.4 Lubricating axis
Requirements:
–The pressure grease gun LUB-1, 647958, is available.
–The roller bearing grease LUB-KC1, 684474, Elkalub VP 922, is available.
–The lubrication adapter, axial output, LUB-1-KE, 744167, is available.
1. Calculate the load comparison factor fv with the formula for combined loads è10.1 Technical
data, mechanical.
Festo — ELGT-BS — 2023-07a

2. Take the lubrication interval Sint as a function of the load comparison factor fv from the character-
istic curve.
3. Determine the load factors:
–Dusty and dirty environment.
–Nominal stroke 300 mm or 2000 mm.< >
–Ambient temperature +40 °C.>
–Service age 3 years.>
–The travel profile matches triangular operation, e.g.frequent acceleration and braking.
4. If there is a load factor, halve the lubrication interval S
int. If there are multiple load factors, reduce
the lubrication interval Sint to a quarter of the standard interval.
5. If necessary, replace the needle point of the pressure grease gun with the lubrication adapter with
axial or radial outlet.
6. Press the pressure grease gun onto the lubrication nipple for the ball screw. Press in the roller
bearing grease at the rear.
