4.2 Function
The electric cylinder unit 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.

8 Commissioning
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.
WARNING!
Severe, irreversible injuries from accidental movements of the connected actu-
ator technology.
Unintentional movements of the connected actuator technology can result from
exchanging the connecting cables of a servo drive or between servo drives.
• Before commissioning: All cables must be correctly assigned and connected.
WARNING!
Danger of burns from hot housing surfaces.
Metallic housing parts can reach high temperatures during operation.
Contact with metal housing parts can cause burn injuries.
• Do not touch metallic housing parts.
• After the power supply is switched off, let the device cool down to room tem-
perature.
• A new homing is only necessary if the reference end position Ref or the useful
range is changed.
• When homing, the Start Press Position PosStart Press is equated with the new
end position LimOut.
8.1 Commissioning "DIO Operation (digital I/O)"
Preparation
1. Check the mounting of the drive system.
2. Check wiring of power supplies [Power], [Logic] and digital I/O (DIO) [Logic].
Processing
1. Switch on load voltage.
2. Switch on logic voltage.
3. Wait for initialisation until LED C/Q lights yellow.
4. Parameterise (optional): Velocities (Speed In/Speed Out), Force/Torque
(Force), Reference End Position Ref (Reference) or Start Press Position PosStart
Press (Start Press).

è Tab. 3 Parameterise and Control Homing
è Tab. 4 Parameterise and Control End-to-End Operation
The drive system is ready for operation and can be controlled via the DIO control
interface (digital I/O). With the first motion task and after each restart, the posi-
tion of the reference end position "Ref" is re-initialised (drive first moves to the
reference end position "Ref" before the actual motion task is executed), LED C/Q
lights green.
8.2 Commissioning: IO-Link Operation
Preparation
1. Check the assembly of the drive unit.
2. Check the wiring of the power supplies [Power] and the IO-Link interface
[Logic].
3. Install the application software.
4. Open IODD file in the application software èwww.festo.com/sp.
Processing
1. Switch on load voltage.
2. Switch on logic voltage via IO-Link master.
3. Wait for initialisation until LED C/Q lights yellow.
4. Establish IO-Link connection with the drive system.
5. Parameterise (optional):

Force, Start Press PositionPosStart Press (PositionStartPress) or End posi-
tionLimOut (End PositionOut)
è Tab. 3 Parameterise and Control Homing
è Tab. 4 Parameterise and Control End-to-End Operation
The drive system is ready for operation and can be controlled via the IO-Link inter-
face. With the first motion task and after each restart, the position of the refer-
ence end position "Ref" is re-initialised (drive first moves to the reference end
position "Ref" independently of the motion task before the actual motion task is
executed), LED C/Q flashes green.

Fig. 7 HMI menu
9.4 Homing
During homing, the positions of the mechanical stops MechIn/ MechOut are
determined in order to calculate the end positions LimIn (Ref)/LimOut for the
dimension reference system.
Before the homing run is carried out, the drive is de-energised for a required re-
initialisation. Then the power supply is restored and the homing process starts.
WARNING!
Risk of injury due to unexpected movement of components.
When starting the homing run, the drive is disconnected from the power supply
for a short time. This can cause unexpected movements of the connected mechan-
ics and crush parts of the body.
• Bring moving parts of the connected mechanical system into a safe position.
• A new homing is only necessary if the reference end position Ref or the useful
range is changed.
• When homing, the Start Press Position PosStart Press is equated with the new
end position LimOut.

9.5 End-to-end Operation
In end-to-end operation with or without press function, the unit can be moved
between the end positions LimIn/LimOut.

Automatic Saving of Device Data
Changes to device data are automatically saved permanently (flash memory). The
flash memory is designed for 100,000 write cycles. Frequent changes to the
device data (e.g.when using the device for positioning tasks via IO-Link) can
cause damage to the device.
Every time the logic voltage is switched on, the position of the reference end posi-
tion"Ref" is re-initialised with SpeedRef with the first motion task. When moving
to theLimOut end position, theLimOut end position is approached at
theSpeedOut velocity.

Diagnostic messages "Warnings and Errors" are displayed by the LED C/Q and
menu and parameters LED displays.
In DIO mode, errors are reported to the controller via the sensor signal combina-
tion "1–1".
Errors can be reset as follows:
– DIO mode èreset of logic voltage
– IO-Link operatingèparameter "Quit Error" (0x0029.3 or 0x0107.0)
The first error that occurred is always displayed.

1) Maximum value for Speed In/Speed Out at level10
2) Maximum value for force at level10
3) The force is controlled and evaluated by regulating the motor current. Depending on the mechanism of the
drive, a linear force can be determined from the level of current measured. The target is set as a percent-
age of the rated motor current and may differ from the actual force at the electric cylinder. In the case of
low set force levels, the influence of friction in the system on the running behaviour and the actual force on
the electric cylinder must also be taken into account.
