4 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.

Axial kit EAMM-A Parallel kit EAMM-U
Tab. 1: Overview of motor mountings
Requirement
–Only loosen screws or threaded pins that are described in the directions in the
instruction manuals.

6.4 Mounting cylinder
High mechanical loads on the mounting connections
If high parallel torques are applied to the drive system at the same time, this will
result in high mechanical loads at the mounting interfaces.
• If the mounting position is inclined or horizontal with direct fastening, the drive
system will require additional support near the motor mounting.
Requirement

Torque on the Piston Rod
During commissioning and operation, the piston rod may only be operated
without torque.
If external torques occur, an external guide must be used.
Mounting the attachment component on the piston rod
When mounting the attachment component, do not exceed the maximum torque
of the piston rod. The maximum torque of the piston rod may only be used for a
short time during mounting è Tab. 7 Information on attachment components.
Collision-free Torque-free Guide load
Tab. 5: Requirement for attachment components
Requirement:
–No collision in the range of motion of the attachment component with motor,
mounting components and sensor components.
–No transverse load or torque on the piston rod.
Absorb external forces and torques by an external guide.
–Minimise guide load. Short lever arms from the piston rod thread to the
force application points and centre of gravity of the add-on elements.
1. Select accessories è www.festo.com/catalogue.
2. Screw the lock nut onto the male thread of the piston rod or attachment
component.
3. Rotate or place the attachment component on the piston rod.
4. Tighten lock nut.
The tightening torque must not act on the piston rod. Counterhold with a
suitable tool on the spanner flat of the piston rod.
Observe maximum tightening torque.

–Referencing to reference switch or end position.
–Query of end positions or intermediate positions.
–Prevention of hard impacts at the end positions.
–Prevention of contamination in the slots.
1. Select accessories è www.festo.com/catalogue.
2. Mount the sensor (reference or query):

–Fasten cable.
Instruction manuals è www.festo.com/sp.
Sensor bracket EAPM
Mounting via profile groove
–Protect the sensor from external magnetic or
ferritic influences, e.g. min. 10 mm distance
to slot nuts.
–Preferably use hardware limit switches with
N/C contact function to guarantee protection
in the event of a sensor failure.

Tab. 8: Overview of sensor mountings
Connecting sealing air
The use of sealing air at approx. ± 0.02 MPa (± 0.2 bar, ± 2.9 psi) reduces or
prevents subsequent contamination:
–The application of negative pressure minimises the release of abraded particles
into the environment.
–The application of overpressure reduces the penetration of dirt into the
drivetrain.

7 Commissioning
7.1 Safety
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.
7.2 Commissioning procedure
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.
When the motor is removed, the motor encoder loses its absolute reference to the
reference mark, e.g. by turning the motor drive shaft.
• Carry out a homing run every time the motor is mounted in order to establish
the absolute reference between the motor encoder and the reference mark.
Torque on the Piston Rod
During commissioning and operation, the piston rod may only be operated
without torque.
If external torques occur, an external guide must be used.
Running noises during operation
Identically constructed axes can generate different running noises depending on
the parameterisation, mode of operation, type of mounting, installation environ-
ment and components.
For use with reduced particle emission
Clean product è 9.2 Cleaning.
Requirement
–Mounting of the drive system is checked.
–Installation and wiring of the motor is checked.
–No foreign objects in the movement space of the drive system.
–Maximum permissible feed force and drive torque not exceeded as a function
of acceleration, deceleration (e.g. stop function, quick stop), velocity, moving
mass and mounting position.
–Cylinder not mechanically overloaded and dynamic setpoint deviation not
exceeded due to force peaks and torque peaks or overshoot effects, e.g. over-
running the end position.
Limit overloads and overruns by jerk limitation, reduced acceleration and decel-
eration setpoints or optimised controller settings.
–Control run and homing with reduced setpoint values for speed, acceleration
and deceleration.
–No test run to mechanical end stops.
–Software end positions ≥ 0.25 mm away from the mechanical stops.
Steps Purpose Note
1. Check
travel
Determine the direc-
tion of travel of the
piston rod
–Direction of movement of piston rod, clockwise spindle:
–Retracting: rotate drive shaft clockwise.
–Advancing: rotate drive shaft anti-clockwise.
–The direction of movement of the piston rod for positive
and negative position values depends on the mounting
position of the motor on the cylinder, e.g. parallel or axial
kit.
–Set a required reversal of direction of rotation via param-
eters in the servo drive or controller.
2. Homing Determination of
the reference point
and adjustment of
the dimensional ref-
erence system
–during the initial
start-up proce-
dure
–after replacement
of the motor
Permissible reference points:
–towards reference switch:
Travel at reduced velocity è
12 Technical data.
–towards end position:
do not exceed maximum values
è Tab. 11 Speed and
energy at the end positions.
Additional information Instruction manual of the driveè
system, è
www.festo.com/sp.
3. Test run Checking the oper-
ating conditions
Check application requirements:
–Piston rod runs through the complete travel cycle in the
specified time.
–The piston rod stops travel when a limit switch or soft-
ware end position is reached.
After a successful test run, the drive system is ready for operation.

8 Operation
WARNING
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.

• With working stroke less than 2 x spindle pitch... P:
• Perform a lubrication run within 10 travel cycles with a minimum stroke of
≥ 2 x spindle pitch.
