The LA25 with IO-Link and M12 connector is a
plug-and-play solution.
If flying leads is the preferred option, please be aware that
the LINAK cable colours differ from the IO-Link standard.
The cable colours from the actuator and the M12 port
numbers are specified in the table below.
In a setup where the violet and white wires are not used,
we strongly recommend insulating these to avoid short
circuits and eventually damaging the actuator.

Input/Output Specification Comments
Description IO-Link is standardised IO technology (IEC 61131-9)
for the communication with actuators. The point-to-point
communication is based on the long established actuator
connection without additional requirements regarding the cable
material. IO-Link is no fieldbus but the further development of
the existing, tried-and-tested connection technology for
actuators.

IO-Link is fieldbus independent and can be integrated into all
fieldbus systems worldwide.
Transmission rate: 38.4 kbaud (COM 2)
Max cable length: 15 meters

Violet Service interface Only BusLink can be used as service interface.
Make sure that the violet and white wires are not short-circuited
White Service interface GND
Yellow Not used
Please note that version 1.0 of IO-Link does not support data storage. Therefore, it is recommended to disable the data storage
feature on the PLC/IO-Link master.
Data storage is a recommended feature in IO-Link, which makes it easy to replace an existing device with a substitute.

Parameter and diagnostic data
On the IO-Link master, there are standard IO-Link parameters available such as e.g. Product ID and firmware revi-
sion. There are also LINAK specific parameters available. These include configuration of the beaviour in outwards

Checklist - First time installation
To guide you through the process of integrating the first LA25 IO-Link in your system, here is a checklist
with the most important steps to consider:
Configure the IO-Link master to “Type B / Class B”
Make sure that the amperage rating of the IO-Link master port is sufficient (min. 2 A)
If not, we strongly recommend to power the motor seperately (read more here)
Plug in the M12 connector or wire up the actuator with flying leads to the master
Make sure you receive data from the actuator
Indicating that communication is OK
Make sure that the data order is correct
Read more about this here
Start moving!
Send a “clear error command”
0xFFFC or 65532

FAQs - Troubleshooting
Based on input from our customers, here are some of the frequently asked questions that might help
you to troubleshoot an actuator in an IO-Link network:
Why is the actuator not running despite giving it a run command?
If the actuator is not running when applying a run command (0xFFFD/65533 for out and 0xFFFE/65534
for in), please check the following:
1. Make sure power is applied from the power supply
2. Send a “clear error” (0xFFFC/65532) command before sending a run command
Does the actuator support data storage?
The current version (v.1.1) of LA25 IO-Link supports data storage.
This will make replacements easier, since the parameters are stored directly in the master.
Why do I get feedback (data) but the actuator is unable to run?
The LA25 is designed with a split supply PCB. This means, that an IO-Link master can receive data from the
actuator, despite not supplying 24 VDC to the motor itself from a power supply.
1. Make sure power is applied from the power supply to the brown and blue wires - see port configu-
ration (Class B)
2. If the actuator is powered directly from the master, this must meet the amp requirements as speci-
fied on the product label (max. 2.5 amps on a standard LA25)
Still experiencing problems with your actuator?
Please contact your local LINAK office for technical support.
Where can I find the latest IODD file?
On the official IODD Finder, you can always find the latest version for LA25 - visit ioddfinder.io-link.com
Why does the PLC show a reversed data order?
On most PLCs and IO-Link masters, the IODD file will ensure the correct order of data input/output bytes
according to the table above. However, some controllers may reverse the data order. Please make sure the
correct Most Significant Byte [MSB] and Least Significant Byte [LSB] is matching your configuration.
If you experience maximum feedback data values (position, current and/or speed), 0xFF [255] for byte data
types and 0xFFFF [65535] for integer data types, the order in most likely reversed.
What has the highest priority - process or parameter and diagnostic data?
Commonly referred to as cyclic and acyclic data. For example, current limit value in amps can be set in both
cyclic and acyclic data. In this case the lowest value determine when the actuator will stop.
