Safety instructions
–
Observe labelling on the product.
–
Prior to assembly, installation and maintenance work: Switch off power supply,
ensure that it is off and secure it against being switched back on.
–
Store the product in a cool, dry, UV-protected and corrosion-protected environ-
ment. Ensure that storage times are kept to a minimum.
–
Observe tightening torques. Unless otherwise specified, the tolerance
is ± 20 %.
2.2
Intended Use
The electric cylinder is intended to be used for positioning payloads in combina-
tion with tools or as a drive when external guides are used.
2.3
Training of qualified personnel

Product overview
4.1
Function
The electric cylinder converts the rotary motion of the mounted motor into a linear
motion of the non-rotating piston rod. The lead screw converts the torque of the
motor into a feed force. The linear movement of the piston rod is guided by the
guide in the guide ring. Sensors enable the monitoring of end positions, reference
position and intermediate position.

Assembly
6.1
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 uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
6.2
Unpacking
1. Open packaging.
2. Remove all transport materials (e.g. foils, caps, cardboard boxes).
3. Remove the product from the packaging and place it on the mounting surface.
4. Dispose of packaging and transport materials.
6.3
Mounting the motor
Transverse load on the drive hub
When mounting the motor and motor mounting kit, do not exceed the maximum
transverse load F
R
of the drive hub (e.g. toothed belt tension when mounting the
parallel kit)

Tab. 1: Overview of motor mountings
Requirement
–
Only loosen screws or threaded pins that are described in the directions in the
instruction manuals.
–
Sufficient space for reaching and securing the sealing air connection
1. Select the motor and motor mounting kit from
Festo
If other motors are used: observe the critical limits for forces, torques and
velocities.
2. Fasten motor mounting kit, observe instruction manual
3. Fasten the motor without tension. Support large and heavy motors.
Connect motor cables only on completion of mounting.
6.4
Mounting the cylinder
High mechanical loads on the mounting connections
If high parallel torques are applied to the drive system at the same time, this leads
to high mechanical loads at the mounting interfaces.
• If the mounting position is inclined or horizontal mounting position with direct
mounting, the drive system requires additional support near the motor
mounting.
Requirement
–
No collision with mounting and sensor components in the movement space of
the attachment component.
–
Sufficient space to reach maintenance interfaces.
–
Sufficient space for reaching and securing the sealing air connection.
–
Flat mounting surface maximum 0.2 mm over the stroke length of the bearing
surface.
–
No distortion or bending when installing the product.
1. Select mounting attachments
2. Place the mounting attachments on the support points.
3. Tighten retaining screws.
Observe the maximum tightening torque and screw-in depth.
