2.2 General Warning Notes
The Module 68 must only be commissioned by specialists who have received safety-technical
instructions and are able to assess potential dangers.
Furthermore, all chapters of these operating instructions must have been read and understood
completely.
DANGER
Warning of dangerous electrical voltage.
The system must be powered down for all assembly, disassembly or repair work.
Non-observance of the safety provisions may cause death.
WARNING
Linear modules must only be operated with their protective device/s.
Linear modules always have to be operated in connection with suitable safety devices
(e.g., safety cell, protective room, protective housing, light curtain).
CAUTION
Warning of hot surface.
During operation, the heated drive, in particular of stepper motors may cause skin burns
when touched. Install a protective device, if possible! Do not touch the marked areas or
wait for an adequate cooling time.
CAUTION
Do not remove plugs or clamps when live.
Motor connectors or clamps must not be inserted or disconnected when live.
Risk of burning of the contacts and risk of flying sparks.

3Intended Use
The linear unit Module 68 and Module 68 D (rotating unit) are precise, linear adjustment units with
toothed belt drive that are used in the commercial area as an attachment part in connection with
other components.
In combination with many standardised installation elements and other linear modules of
IEF-Werner GmbH (e.g. easyLINE, module 105, module 105 S and module 142, module 142 S),
complex multi-axis handling systems can be developed as well.
The areas of application of module 68 or module 68 D are accordingly diverse.
They range from:
■Stop adjustment in the wood industry
■Automated assembly lines
■Joining and press in processes in precision engineering
■Loading and unloading station of machine tools up to
■Manipulators for the packaging industry
Figure 2 Linear unit Module 68
3.1 Reasonably foreseeable misuse
The linear module 68 is not to be used for certain applications such as the transport of persons and
animals or as a pressing/bending device for cold working of metal.
Use of the linear module without additional measures is also not possible in special fields of
application, such as the chemical or food industry or in explosive atmospheres.
In case of doubt, consult the manufacturer.

4Assembly Instructions
4.1 Installation Position
The installation position is optional, this means the linear module 68 can be used horizontally as
well as vertically.
NOTICE
In the vertical installation position, use only motors with spring-operated brake to prevent the
lowering of the drive in de-energized condition!

4.4 Installation of actuators
Actuators (pick-up modules, cylinders, etc.) to be installed on the Module 68 are usually attached to
the linear unit using the drill template (see Figure 6, below) on the end plates.
For module 68 D a shaft stub is available (see Figure 7, below).

4.5 Wiring
4.5.1 Motors
NOTICE
The electrical connection of the motors is performed according to the motor data sheet.
For customer-specific motors, the data sheet must be requested from the respective manufacturer
and the motor connected accordingly.
4.5.2 Initiators
Inductive proximity switches (PNP normally closed) are used as standard stroke limitation switches.
NOTICE
The stroke limitation switches are not safety limitation switches according EN60204-1.
The initiators and their supply lines are protected in the carriage or, for the rotating unit
(Module 68 D), in the motor flange cover of the rotating unit drive.
The respective connections are centrally connected to one plug. If an additional reference point
switch is required, it must be installed externally in a suitable position.
