2 Safety
2.1 Safety instructions
–Only mount the product on components that are in a condition to be safely
operated.
–Clean the shafts. The coupling hub [17] will grip without slipping only on a drive
shaft which is dry and free of grease.
–Maintain the alignment of the coupling hub [17].
–If the motor is loosened or turned, homing must be carried out on the axis.
–Select required mounting components. The kit contains all the mounting com-
ponents that may be required.
–Observe tightening torques. Unless otherwise specified, the tolerance is
± 20 %.
2.2 Intended use
2.2.1 Use
The parallel kit connects an axis to a motor in a parallel configuration.
2.2.2 Permissible axes and motors
NOTICE
Overloading can cause malfunction and material damage.
The motor’s output variables must not exceed the permissible values of the
components used.
Permissible values è www.festo.com/catalogue.
• Limit the motor’s output variables accordingly.
•Derive the axis and motor from the interface codes.

Tab. 2: Permissible motors
It is the responsibility of users to qualify third-party motors with the matching
mechanical interface for the combination.
To find out which third-party motors are suitable, contact your regional Festo
contact or call è www.festo.com/sp.
2.3 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can eval-
uate the work and detect dangers. Personnel must have the relevant mechanical
training.

5.1.3 Coupling alignment
NOTICE
Faulty coupling alignment
If dimension Y is incorrectly adjusted, this will cause increased wear of the
toothed belt and may result in mechanical contact between the toothed belt
pulley and the housing or cover.
• Observe distance.
Adjusting dimension Y is measured on the flat face of the mounted adapter
plate [40] with EAMM-U-...-67A.

5.1.5 Tensioning the toothed belt
NOTICE
Toothed belt pretensioning too high.
Impermissible radial loads or shaft break.
Increased wear of the toothed belt and the bearings of axis and motor.
•Avoid excessive toothed belt pretension.
A low toothed belt pretension is recommended.
The toothed belt [5] is tensioned when the strands [D] run approximately parallel:
–Untensioned: y > x
–Tensioned: y L 1 … 1.05 x

6 In operation
CAUTION
Risk of injury from touching hot surfaces.
The motor connecting kit becomes hot due to the heat dissipation of the motor.
• Do not touch the motor connecting kit during operation or immediately after-
ward.
WARNING
Risk of injury due to unexpected movement of components if toothed belt fails.
• Take supplemental safeguarding measures.

7 Maintenance
7.1 Check the toothed belt
The toothed belt [5] is a wearing part è www.festo.com/spareparts.
1. Check toothed belt [5] regularly:
–during maintenance of the machine
–when replacing an axis
2. Replace the toothed belt [5] at the following indicators of wear:
–excessive accumulation of wear particles in the housing
–cracks on the back of the toothed belt
–visible glass fibre cords in the tooth base
7.2 Demounting the toothed belt

With vertical or diagonal mounting position of the axis:
• Observe applicable safety instructions in the instruction manual for the axis.
1. Remove screws [2].
ÄThe motor is movable and can be easily tilted.
2. Move the motor in the direction of the axis up to the stop and tilt it slightly.
