Cleaning
–
If the piston rod is dirty, clean it with a clean, soft and lint-free cloth without
cleaning agents and then apply the lubricant thinly to the piston rod.
–
Clean the other product components with a clean, soft cloth and non-abrasive
cleaning agents.

Acknowledge error
With error acknowledgment, active error messages are deleted from the diag-
nostic memory if the cause of the error was remedied before acknowledgment.
Errors can be acknowledged via the following interfaces:
–
Restart:
–
Logic voltage L

, Power OFF/ON [Logic, Pin 1]
–
HMI:
–
Press and hold
for 3 s
–
DIO, digital inputs:

–
IO-Link, device data:
–

–
IO-Link, process data:
–
0x0029.3 Quit Error = true
–
0x0029.1 and 0x0029.2 = true, 0x0029.5 = any
Diagnostic messages and fault clearance
"Information, Warnings and Errors" diagnostic messages are displayed by the
C/Q LED and menu and parameters LED displays.
Errors are reported to the controller as follows:
–
DIO operation: output signals DO1 and DO2 = 1 [Logic, Pin 2/3]
–
IO-Link operation: ProcessDataInput state "In" (0x0028.1) and state "Out"
(0x0028.2) = true
The first error that occurred is always displayed.

Fault clearance
WARNING
Unexpected movement of components.
Injury due to impacts or crushing.
• Before working on the product, switch off the control and secure it to prevent it
from being switched back on accidentally.
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.
Fault description
Cause
Remedy
Loud running noises
or vibrations or rough
running of the cylinder
Torsional stresses
–
Install the cylinder free of tension. Make
sure that the contact surface is flat
–
Change the layout of the attachment compo-
nent (e.g. payload).
–
Align cylinder and attached guide element
parallel to each other.
–
Use external guide.
Resonant vibration of
the cylinder
Change the travel velocity.
Toothed belt wear
–
Contact local Festo Service.
–
Replace cylinder
Insufficient lubrication
of the piston rod
Lubricate the piston rod
lubrication intervals and accessories.
Vibration at the piston
rod
Operation at the reso-
nance point of the cyl-
inder
–
Change the travel velocity.
–
Change the payload geometry.
Piston rod does not
move
Drive pinion slips
–
Contact local Festo Service.
–
Replace cylinder
Loads too high
Reduce forces and torques. Consider dynamics.
Toothed belt ripped
–
Contact local Festo Service.
–
Replace cylinder
