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.

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 uncon-
trolled into the lower end position.
Bring moving parts of the product into a safe end position or secure them against falling.
6.2 Mounting motor
Observe the limit values for forces, torques and speeds if a non-recommended motor and motor
mounting kit are used.

Sufficient space for maintenance work.
A payload mounting surface flatness of 0.01mm above the slide surface.
Minimise the guide load. Short lever arms from the guide centre to the force application points and
centres of gravity of the payload.
1.
Place centring components in the centring holes.
2.
Position the payload at the intended location.
For cantilever operation position the payload on the end cap or place it on the profile.
For slide operation position the payload on the slide. In the delivery status the centring ele-
ments are placed in centring holes.

For vertical or slanted mounting position: when power is off, moving parts can travel or fall uncon-
trolled into the lower end position.
Bring moving parts of the product into a safe end position or secure them against falling.
When using an additional external guide, ensure that the axes and guide are precisely parallel and
aligned.
Recommendation: use guide mountings with tolerance compensation.
Tension due to manufacturing tolerances may be encountered with axes with additional slides when
mounting an adapter plate supplied by the customer.

6.8 Connecting sealing air or clamping unit
The supply ports of the axis can be used as follows, depending on the product variant:
Sealing air connection: for axes with strip cover ELCC-...-70/90/110-P9.
Clamping unit connection: for axes with attached clamping unit ELCC-...-70/90/110-C.
The use of sealing air at approx. ±0.02MPa (±0.2bar, ±2.9psi) reduces or prevents the following
contamination:
The application of negative pressure minimises the release of abraded particles into the environ-
ment.
The application of overpressure reduces the penetration of dirt into the drive train.
Always use Loctite 222 to seal an open supply port.

1. Remove one plug screw from the threaded hole of the slide or drive head.
2.
Mount the fitting (M5; 0.5 Nm) and connect the tubing.
