Product Description
Device overview

4 Product Description
The inductive linear position sensors of the Li-Q25L series consist of a sensor and a positioning
element. The two components form a measuring system for measuring and converting the
measured variable for length or position.
The sensors are supplied with a measuring length of 100…2000mm: In the 100…1000mm
range, variants are available in 100 mm increments, in the 1000…2000mm range in 250 mm in-
crements. The maximum measuring range of the sensor is determined by its length. However,
the start point of the measuring range can be individually adapted with a teach operation. The
gradient of the output characteristic also stays the same after the start point has been changed.
The sensor is housed in a rectangular aluminum profile. The positioning element is available in
different variants in a plastic housing (cf. Accessories list in chapter 4.5). Sensor and positioning
element comply with degree of protection IP67 and can withstand the vibrations of moving
machine parts as well as being resistant to a number of aggressive environmental media.
Sensor and positioning element together enable contactless and wear-free measuring. The
sensors operate in absolute mode. Voltage failures do not require renewed homing or recalib-
ration. All position values are determined as absolute values. Homing movements after a
voltage drop are unnecessary.

4.3 Operating principle
The LI-Q25L linear position sensors have contactless operation based on the inductive resonant
circuit measuring principle. Measuring is immune to magnetic fields as the positioning element
is not based on a magnet but on a coil system. Sensor and positioning element form an induct-
ive measuring system. An induced voltage generates appropriate signals in the receiver coils of
the sensor, depending on the location of the positioning element. The signals are evaluated in
the internal 16-bit processor of the sensor output via the IO-Link interface.
4.4 Functions and operating modes
4.4.1 IO-Link mode
The devices must be connected to an IO-Link master for operation in IO-Link mode. If the port is
configured in IOL mode, bidirectional IO-Link communication is provided between the IO-Link
master and the device. For this the device is integrated in the controller level via an IO-Link
master. The communication parameters are exchanged first of all; the cyclic data exchange of
the process data (process data objects) then starts.
4.4.2 Output curve
The gradient of the output characteristic also stays the same when the measuring range is
changed. The end point of the measuring range stays the same.

Setting
Setting via IO-Link
18 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
9 Setting and Parameterization
9.1 Settable functions and features
The following functions and properties can be set and used via the IO-Link interface:
nSet the start of the measuring range (zero point): The gradient of the output characteristic
stays the same.
nSetting the process data
– Normal mode: In Normal mode, 16-bit process data corresponds to 65535 increments.
The measuring range is resolved in the increments. Three diagnostic bits are provided
for the resonance coupling.
– Compatibility mode: The measuring range is resolved in 1 µm increments. 32 bits are
provided.
9.2 Setting via IO-Link
The device can be parameterized within the technical specifications (see data sheet) via the IO-
Link communication interface – both offline, e.g. with the configuration tool as well as also on-
line via the controller. An overview of the different functions and properties that can be set and
used for IO-Link mode can be found in the chapter “Setting” and in the IO-Link parameter
manual of the device. Detailed instructions on the parameterization of devices via the IO-Link
interface are provided in the IO-Link commissioning manual.
All the parameters can changed in IO-Link mode via the controller during commissioning as
well as during operation.

V01.01 | 2021/09 19
10 Troubleshooting
The strength of the resonance coupling is indicated by an LED. Any faults are indicated via the
LEDs.
If the device does not function as expected, first check whether ambient interference is present.
If there is no ambient interference present, check the connections of the device for faults.
If there are no faults, there is a device malfunction. In this case, decommission the device and
replace it with a new device of the same type.
