Assembly
4.2 Function
Fig. 2: Functional principle of toothed belt drive with fixed toothed belt
The axis converts the rotary motion of the mounted motor into a linear motion of the cantilever or
slide. The toothed belt drive converts the torque of the motor into a feed force. The linear movement
of the cantilever or slide is accurately guided by the guide. The integrated cover strip prevents abraded
particles from penetrating the immediate vicinity of the drive. The clamping unit is used for holding
loads at standstill or for emergency braking in the event of a power failure. Sensors and displacement
encoder enable query of end positions, reference position and intermediate position.

Commissioning

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.
NOTICE
Elasticity of the toothed belt
The elasticity of the toothed belt generates an additional spring effect at high acceleration and
deceleration, which can lead to an inadmissible nominal/actual deviation when the slide is moved or
when the end position is reached.
• Consider the setpoint deviation determined during the test run during parameterisation of position
setpoint values.
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.
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 protective cover of the cover strip is removed.
–The installation on the motor has been checked.
–There are no foreign objects in the movement space 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.
16
Festo — ELCC-TB — 2023-05c
Maintenance
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 Maintenance
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 Checking toothed belt wear
Checking toothed belt wear
The toothed belt is tensioned for its entire service life.
The toothed belt must not be retensioned.
1. ELCC-...-PU1:
–Initial check: after 1000km.
–Periodic check: every 500km.
ELCC-...-CR/-PU2:
–Initial check: after 5000km.
–Periodic check: every 1000km.
2. If the toothed belt shows visible wear: send the axis to Festo or contact Festo Service
èwww.festo.com.
8.3 Checking cover strip
1. Check the cover strip for wave formation every 2000km.
2. Retension the cover strip as follows if waves are detected.
3. Replace the belt reversals and the cover strip if retension is no longer possible.

3. Tighten the cover strip with a clamping element .1
4. Tighten the screws to 6Nm±10%.
8.4 Checking clamping unit
Clamping unit ELCC-...-C
Check the holding force of the clamping unit at every maintenance interval or after every emergency
braking in the event of a power failure.
The clamping unit must be replaced after 1000 emergency braking operations or after 50,000
clamping operations Contact your local Festo service centre.è
–Check holding function as follows:
1. Move the cantilever or slide to an end position.
2. Exhaust the clamping unit connection
3. Allow the test force (the test pressure) to act on the drive for at least 5s. During this time, the
cantilever or the slide must not move.
The test force and the tolerance window can be taken from the risk assessment of the application.
8.5 Cleaning axis
Clean the product with a clean, soft cloth and non-abrasive cleaning agents.
Removing abraded particles in the drive head
At every maintenance interval remove the particles from the toothed belt and cover strip wear on the
axis or in the drive head as required.
18
Festo — ELCC-TB — 2023-05c
Maintenance
1. Press both interlocks (1) simultaneously up to the stop.
2. With the interlocks (1) pressed, pull the housing (2) off the drive head.
3. Remove abraded particles in the drive head if necessary.
4. Insert the housing into the guide of the interlock and push it onto the drive head until the
interlocks engage.

4. If there is a load factor, halve the lubrication interval Sint. 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,
axial outlet or radial outlet.
6. Press the pressure grease gun on the lubrication nipple of the recirculating ball bearing guide.
Press in the roller bearing grease at the front or left and right.
