Description of functions AMS 338i
The AMS 338i optical laser measurement system calculates distances to fixed as well as
moving system parts. The distance to be measured is calculated according to the principle
of the propagation time of radiated light. Here, the light emitted by the laser diode is reflected
by a reflector onto the receiving element of the laser measurement system. The AMS 338i
uses the "propagation time" of the light to calculate the distance to the reflector. The high
absolute measurement accuracy of the laser measurement system and the fast integration
time are designed for position control applications.
With the AMS 3xxi product series, Leuze electronic makes available a range of internationally relevant interfaces. Note that each interface version listed below corresponds to a
different AMS 3xxi model.

Aligning the laser light spot in the center of the reflector
The laser light spot has to be aligned so that it always hits the center of the opposing
reflector, both at close range as well as at the maximum measurement distance. To align,
use the two M5 Allen screws ("A" in figure 5.2). When aligning please ensure that the
knurled nut and the lock nut ("B" in figure 5.2) are opened wide.
Attention!
To prevent the laser measurement system from moving out of alignment during continuous
operation, subsequently hand-tighten the knurled nut and counterlock with the nut with
WAF4 hexagon socket ("B" in figure 5.2). Knurled nut and nut must not be tightened until
alignment has been completed.
Attention!

Thus, the center-to-center spacing of the two AMS 338i devices with respect to one another
can be calculated as a function of the maximum measurement distance.
To define the minimum parallel spacing between two AMS 338i, it is necessary to distinguish
between three different arrangements of AMS 338i and reflectors.
The AMS 338i are mounted stationary and in parallel on one plane.
Both reflectors move independently of one another at different distances to the
AMS 338i.
Minimum parallel spacing X of the two laser light spots:
X = 100mm + (max. measurement distance in mm x 0.01)
The AMS 338i are mounted stationary and in parallel on one plane.
Both reflectors move in parallel at the same distance to the AMS 338i.
Measurement distance up to 120m: minimum parallel spacing X ≥ 600mm
Measurement distance up to 200m: minimum parallel spacing X ≥ 750mm
Measurement distance up to 300m: minimum parallel spacing X ≥ 750mm

Both AMS 338i move independently of one another at different or the same distances to the reflectors.
Measurement distance up to 120m: minimum parallel spacing X ≥ 600mm
Measurement distance up to 200m: minimum parallel spacing X ≥ 750mm
Measurement distance up to 300m: minimum parallel spacing X ≥ 750mm
Notice!
Please note that when the AMS 338i are mounted in a mobile manner, travel tolerances could
cause the two laser light spots to move towards each other.
Take the travel tolerances of the vehicle into account when defining the parallel spacing of
adjacent AMS 338i.
5.2.3
Parallel mounting of AMS 338i and DDLS optical data transmission
The optical data transceivers of the DDLS series and the AMS 338i do not interfere with one
another. Depending on the size of the used reflector, the DDLS can be mounted with a
minimum parallel spacing of 100mm to the AMS 338i. The parallel spacing is independent
of the distance.

General information
The AMS 338i measures distances against a reflective tape specified by Leuze electronic.
All provided specifications for the AMS 338i, such as the operating range or accuracy, can
only be achieved with the reflective tape specified by Leuze electronic.
The reflective tapes are available as adhesive tapes, affixed to a metal plate and with an
integrated heater especially for use at low temperatures. Reflective tapes with heating have
the designation "Reflective tape …x…-H", where "H" is an abbreviation for the heating
variant.
The reflective tapes/reflectors must be ordered separately. The choice of size is left to the
user. In chapter 6.3, recommendations on reflector size are provided as a function of the
distance that is to be measured. In any case, the user must check to determine whether the
recommendation is suitable for the respective application.
6.2
Description of the reflective tape
The reflective tape consists of a white, microprism-based reflective material. The microprisms are protected with a highly transparent, hard protective layer.
Under certain circumstances, the protective layer may lead to surface reflections. The
surface reflections can be directed past the AMS 338i by positioning the reflective tape at
a slight incline. The inclination of the reflective tape/reflectors is described in chapter 6.4.2.
The required pitch can be found in table 6.1 "Reflector pitch resulting from spacer sleeves"
on page 35.
The reflective tapes are provided with a protective foil that can easily be pulled off. This must
be removed from the reflector before the complete system is put into operation.

Specifications of heated reflectors
The reflective tape is affixed to a heated, thermally insulated base. The insulation results in
a very high energetic efficiency.
Only the reflective tape is kept at the specified temperature by the integrated heater.
Through the insulation on the back, the generated heat cannot be transferred via the steel
construction. Energy costs are greatly reduced in the case of continuous heating.

Selecting reflector sizes
Depending on system design, the reflector can be mounted so that it travels on the vehicle
or it can be mounted at a fixed location.
Attention!
The reflector sizes shown below are a recommendation from Leuze electronic for on-vehicle
mounting of the AMS 338i. For stationary mounting of the AMS 338i, a smaller reflector is
generally sufficient for all measurement distances.
On the basis of the system planning and design, always check whether mechanical travel
tolerances may require the use of a reflector larger than that which is recommended. This
applies, in particular, when the laser measurement system is mounted on a vehicle. During
travel, the laser beam must reach the reflector without interruption. For on-vehicle mounting
of the AMS 338i, the reflector size must accommodate any travel tolerances that may arise
and the associated "wandering" of the light spot on the reflector.

Mounting the reflector
6.4.1
General information
Self-adhesive reflective tapes
The reflective tapes of the "Reflective tape …x…-S" self-adhesive series must be affixed
to a flat, clean and grease-free surface. We recommend using a separate metal plate, which
is to be provided on-site.
As described in table 6.1, the reflective tape must be angled.
Reflective tapes on metal
The reflective tapes of the "Reflective tape …x…-M" series are provided with corresponding
mounting holes. Spacer sleeves are provided in the packet for achieving the necessary pitch
angle. For further information see table 6.1.
Heated reflectors
The reflective tapes of the "Reflective tape ...x...-H" series are provided with corresponding
mounting holes. Due to the voltage supply affixed on the rear, the reflector cannot be
mounted flat. Included in the package are four distance sleeves in two different lengths. Use
the distance sleeves to achieve a base separation to the wall as well as the necessary pitch
for avoiding surface reflection. For further information see table 6.1.
The reflector is provided with a 2m-long connection cable for supplying with 230VAC.
Connect the cable to the closest power outlet. Observe the current consumptions listed in
the specifications.
Attention!
Connection work must be carried out by a certified electrician.
6.4.2
Mounting the reflector
The combination of laser measurement system and reflective tape/reflector is mounted so
that the laser light spot hits the tape as centered as possible and without interruption.
For this purpose, use the alignment elements provided on the AMS 338i… (see chapter 5.2
"Mounting the AMS 338i"). If necessary, remove the protective foil from the reflector.
Attention!
The "TOP" label mounted on the reflectors should be aligned the same as the connections
of the AMS 338i.
Example:
If the AMS 338i is mounted so that the M12 connections are on the top, the "TOP" label of
the reflector is also on the top. If the AMS 338i is mounted so that the M12 connections are
on the side, the "TOP" label of the reflector is also on the side.

Reflectors
Notice!
The reflector must be angled. To do this, use the spacer sleeves. Angle the reflectors so that
the surface reflections of the foil seal are deflected to the left, right or upwards, chapter
6.4.3 gives the correct pitch with respect to the reflector size and, thus, the length of the
spacers.

The SSA is a freely configurable position-independent address which is often used for the
so-called hot connect. The values range from 0 to 65535. The SSA is persistently stored on
the AMS 338i and is available after the next boot-up. A second option is to write the SSA
to the Eeprom and the associated ESC register via the master (typically TwinCAT). In this

case, too, the SSA is persistently stored in the AMS 338i. The master (TwinCAT) can determine whether it wants to use the EtherCAT address (auto-increment address) or the SSA to
address the AMS. For SSA, the position-dependent EtherCAT address is also set to the value
of the SSA. Otherwise, the auto-increment address is entered into the ESC register which
contains the EtherCAT address. The EtherCAT address is not stored in persistence memory,
but written into the respective register by the master when the status changes from INIT to
PREOP.

To change the language, no password needs to be entered nor must password enabling
be activated. The display language is a passive operational control and is, thus, not a function parameter, per se.

As long as parameter enabling is activated, the entire AMS 338i display is inverted.
As long as parameter enabling is activated, communication between control and AMS 338i
is interrupted. The continued networking via BUS OUT is retained.
Notice!
If a password was stored, parameter enabling is not possible until this password is entered,
see "Password for parameter enabling" below.
Password for parameter enabling
Parameter entry on the AMS 338i can be protected with a password. The password can be
changed via the CoE online dictionary, object 0x2300h, sub-index 0x05h.
For parameter enable via the display, the password must be entered. If parameter enabling
has been activated after successfully entering the password, parameters can temporarily
be changed via the display.
After parameter enable has been deactivated, all changes made at the display are overwritten by the CoE online dictionary, object 0x2300h, sub-index 0x05h (see above). If a new
password has been assigned, this, too, is overwritten by the password defined in the online
dictionary.
Notice!
The master password 2301 can enable the AMS 338i at any time.

General information on EtherCAT
EtherCAT is an Ethernet-based fieldbus initialized by Beckhoff. The EtherCAT Technology
Group (ETG) is the official standardization partner of the IEC working groups.
EtherCAT has been an IEC standard since 2005.
• IEC 61158: protocols and services
• IEC 61784-2: communication profiles for the specific device classes
All EtherCAT-specific communication mechanisms are explained in detail in the standards
mentioned. The technical description of the AMS 338i will describe parts of the
IEC standard, if this serves basic understanding.
9.2
EtherCAT topology
EtherCAT permits a wide range of topologies such as line, tree, ring, star and their combinations. The bus or line structure known from the fieldbuses is thus also available for
EtherCAT.
From the Ethernet perspective, an EtherCAT bus segment is nothing but a single, large
Ethernet participant which receives and transmits Ethernet telegrams. However, there are
many EtherCAT slaves within the "participant", not just a single Ethernet controller.
Figure 9.1:
Leuze electronic
Topology example
AMS 338i
51
TNT 35/7-24V
Telegrams are transmitted on one line pair in the "processing direction" from the master to
the slave. The EtherCAT device processes the frames only in this direction and sends them
to the subsequent device until the telegram has passed through all devices. The last device
returns the telegram on the second line pair in the cable in "forward direction" back to the
master. Here, EtherCAT always forms a logical ring structure independent of the topology
installed.
EtherCAT interface
9.3
EtherCAT – General information on wiring
The wiring uses the Industrial Ethernet fieldbus cable common in industry. For the AMS 338i,
the EtherCAT connection is made via D-coded M12 connectors. A Cat. 5 Ethernet cable
should be used for wiring.
Leuze electronic offers cables ready-made and featuring a D-coded M12 connector on one
end and an open cable end at the other.
For further information, see chapter 7 "Electrical connection" and see chapter 11.3.5
"Accessory ready-made cables for EtherCAT".
The individual AMS 338i devices in a line topology are connected to each other using the
"KB ET - … - SSA" cable with ready-made D-coded M12 connectors on both ends, see
table "Order codes for EtherCAT connection cables" on page 88.
For unavailable cable lengths, you can configure your cables yourself. For this purpose,
Leuze electronic offers a D-coded M12 connector for Bus IN and Bus OUT. When doing
so, make certain that you connect TD+ on the M12 connector with RD+ on the RJ-45
connector and TD- on the M12 connector with RD- on the RJ-45 connector, respectively,
etc.
For the connection technology transition from M12 to RJ45, a "KDS ET M12 / RJ 45 W - 4P"
adapter is available.

EtherCAT - electrical connection
For contacting BUS IN and BUS OUT, we recommend our ready-made EtherCAT cable (see
chapter 11.3.5 "Accessory ready-made cables for EtherCAT").
To establish an EtherCAT network, the AMS 338i provides a receiving bus labeled BUS IN
on the device, and a forwarding bus labeled BUS OUT. The AMS 338i can be connected to
BUS OUT or to BUS IN using a stub cable.
 For the connection of two AMS 338i, the "KB ET - … - SSA" ready-made cables are preferred, see table 11.3.5 "Accessory ready-made cables for EtherCAT" on page 87.
If you use user-configurable cables, note the following:
Notice!
The entire connection cable must be shielded. The shielding connection must be at the same
potential on both ends of the data line. This prevents potential compensating currents over
the shield and possible interference coupling by compensating currents. The signal lines
must be stranded in pairs.
Use CAT 5 cable for the connection.

9.6
Starting the AMS 338i on the EtherCAT
INIT
The AMS 338i initializes itself. No direct communication between the master and AMS 338i
is possible. The EtherCAT master will transit the AMS 338i step by step into the "operational"
state.
In the status change from "INIT" to "PREOP", the TwinCAT or master writes the so-called
EtherCAT address (=station address) to the respective register of the EtherCAT slave
controller (here: AMS 338i). This EtherCAT address is typically specified in relation to the
position, i.e., the master's address is 1000, the first slave's address is 1001, etc. This is also
called the auto-increment method.
PRE-OPERATIONAL
The master and the AMS 338i exchange application-specific initializations and devicespecific parameters. In the PRE-OPERATIONAL state, configuration is initially possible via
SDOs only.
SAFE-OPERATIONAL
The "start input update" command puts the measurement system into the save-operational
state. The master produces output data, but input data are not considered. This means the
AMS 338i does not return output data (=PLC input data) in SAFEOP. The AMS does not
process input process data (=PLC output data). Mailbox communication via CoE services
is possible.
OPERATIONAL
The "start output update" command puts the measurement system into OPERATIONAL
state. In this state, the AMS 338i supplies valid input data and the master valid output data.
After the AMS 338i has detected the data received via the process data service, the state
transition is confirmed by the AMS 338i. If the activation of the output data was not possible,
the measurement system remains in the SAFE OPERATIONAL state and outputs an error
message.

The count direction changes the sign during velocity measurement.
For the EtherCAT interface, no negative position values can be transferred. In this case, the
value 0 is output at the EtherCAT interface.

Sub-index 05 offset value
The offset value in mm or inch/100, in accordance with the unit selected.
Output value = measurement value+offset.
If the preset value has been activated by a corresponding trigger signal, the preset value
has priority over the offset value.
Preset value and offset value are not offset against each other. The resolution of the offset
value is independent of the position value resolution selected. The offset value is active
immediately without any further release.
Sub-index 06 free resolution
Free resolution in mm/1000 or inch/100000, in accordance with the unit selected.
The "free resolution" parameters from sub-index 03 and the "value free resolution" from
sub-index 06 are mutually dependent. The value of the free resolution is multiplied by mm/
1000 or inch/100000 in accordance with the unit selected. The multiplication product is then
the free resolution that has been set.

9.7.6.6 Object 2020h Velocity
Outputs the current velocity with the configured resolution. The unit (metric or inch) is set
in object 2000 sub-index 02 and also applies to the velocity. If no change is made in
object 2000 sub-index 02, the AMS 338i uses the metric default setting.
The sign of the velocity is dependent on the count direction in object 2000 sub-index 04.
In the default setting a positive velocity is output when the reflector moves away from the
AMS 338i. When the reflector moves towards the AMS 338i, negative velocities are output.
If the "negative" count direction is configured in object 2000 sub-index 04, the velocity signs
are reversed.
The integration time for the velocity averages all velocity values calculated during the
selected period to yield a velocity value. This average velocity value is output via the interface.

performed from position start to position end. For example, if the position start is "5500"
and the position end is "5000", the direction-dependent check is only performed in the direction from "5500" to "5000". The limit value is not active in the opposite direction.
If the check is independent of direction, the order of position start and position end is irrelevant. Depending on the selected switching mode, if the value is above or below the defined
limits, the limit value status in object 2026h is set and, if configured, the switching output is
set via object 2050h or 2051h.

Explanation on sub-index 06 "heating control"
0 = Standard (10°C … 15°C)
1 = Extended (30°C … 35°C)
The sub-index 06 is available as standard, but functions only for devices with integrated heating (AMS 338i … H).
Sub-index 06 defines a switch-on/switch-off range for the heating control. The extended
switch-on/switch-off range for heating may provide relief in the event of condensation problems. There is no guarantee that no condensation will occur on the optics in the extended
switch-on/switch-off range due to the limited heating capacity.

Objects of the AMS 338i from the DS406 class 1 encoder profile
The AMS 338i adopts the profile from CANopen. The profile puts prescribed characteristics
of the participant on defined object addresses.
The AMS 338i communicates according to the specifications in profile "DS406" class 1.
For class 1, it is mandatory to describe the following objects.

Type overview and accessories
Notice for connecting the EtherCAT interface!
The entire connection cable must be shielded. The shielding connection must be at the same
potential on both ends of the data line. This prevents potential compensating currents over
the shield and possible interference coupling by compensating currents. The signal lines
must be stranded in pairs.
Use CAT 5 cable for the connection.
