General information
1.3 Description of functions AMS 335i
The AMS 335i 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 335
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.

Installation and mounting
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!
The device must not be opened. Failure to comply will render the guarantee void. Warranted
features cannot be guaranteed after the device has been opened.

6 Reflectors
6.1 General information
The AMS 335i measures distances against a reflective tape specified by Leuze electronic.
All provided specifications for the AMS 335
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 335
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 34.
The reflective tapes are provided with a protective fo il that ca n easily be p ulled off . This mus t

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.

6.3 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 335
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 335
and the associated "wandering" of the light spot on the reflector.
i, the reflector size must accommodate any travel tolerances that may arise

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.
Reflectors
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 335
"Mounting the AMS 335i"). 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 335
Example:
If the AMS 335
the reflector is also on the top. If the AMS 335
on the side, the "TOP" label of the reflector is also on the side.

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 335i can be protected with a password. With the AMS 335i,
the password is defined via the EDS file (class 100, instance 1). Thus, the password cannot
be changed by means of display entry.
To activate parameter enabling via the display (e.g., for changing an address), the password
defined in the EDS file must be entered. If parameter enabling has been activated after
successfully entering the password, parameters can temporarily be changed via the display.
After deactivating the parameter enable, all changes made to the display are overwritten by
the start-up sequence that may be stored in the control (see above). If a new password has
been assigned, this, too, is overwritten by the password defined in the EDS file.
Notice!
The master password 2301 can enable the AMS 335
i at any time.

9.1 General information on CANopen
9.1.1 Topology
Termintator
Figure 9.1: Bus topology
The CAN bus is a serial 2-wire bus system to which all participants are connected in parallel
(i.e., using short drop lines). To avoid reflections, the bus must be terminated with a terminating resistor of 120ohm at each end of the trunk line. Terminating resistors are also
required for very short trunk line cable lengths.

resistor, see chapter 11 "Type overview and accessories".
i is the last participant in the trunk line, the trunk line can be terminated via
9.1.2 Bus line (trunk line)
For CAN, the maximum cable length of the trunk line is predominantly limited by the signal
propagation time. The multi-master bus-access process (arbitration) requires that the
signals are present virtually simultaneously at all nodes/participants. Therefore, the cable
length of the trunk cable must be adapted to the baud rate.
Baud rate Bus length

500kbit/s < 100m

handbook, the term "address" is used, which is identical to "Node ID".
Each participant connected to CANopen is assigned its own address (Node ID).
Up to 127 participants can be connected to one network. The addresses range from 1 to
127. The address 0 is usually reserved for the CANopen master.
!
Notice
The "Layer Setting Services (LSS)" function is not supported by the AMS 335i. For this reason, the address must be set manually via the display/panel of the AMS.
9.2.1 Entering the address via the display
To enter the address via the display, proceed as follows:
Activate parameter enabling.
Select the CANopen submenu.
Select the Node ID menu item.
Enter an address between 1 and 127.

9.5 Communication mechanisms of the AMS 335i on CAN
In a CANopen network, all participants have in principle equal privileges. Each participant
can initiate its data transmission independently. Here, the arbitration specified by the CIA
controls the access of the individual participants to the network. Generally, each CAN participant listens in on the bus. The transmission process is started only if the bus is not occupied
by another CAN participant. When transmitting, the current bus status is always compared
to the own transmitted frame.
If several participants start a transmission simultaneously, the arbitration process decides
which participant gains access to the network next. The individual participants are integrated into a prioritization scheme via their bus address and the type of data to be transmitted (index address of the data). Process data (PDOs) of a device are transmitted with a
higher priority than, for example, variable objects (SDOs) of a device.
The node address of the participant is another criterion for prioritizing a participant in the
network. The smaller the node address, the higher the priority of the participant in the
network.
Since every participant compares its own priority with that of the other participants at the
time of bus access, the participants with low priority discontinue their transmission activities
immediately. The participant with the highest priority obtains temporary access to the bus.
The arbitration process controls the access of all participants so that even participants with
a low priority have access to the bus.
9.5.1 Device profile of the AMS 335i
CANopen describes the characteristics of participants in so-called profiles. The AMS 335i
communicates according to the specifications in profile "DS406" class 1.
The profile defines the accesses to an absolute linear encoder.
The AMS 335
i is designed as a slave participant and cannot take on master functionality.
9.5.2 Object directories
All process data and parameters are stored as objects in the AMS 335i. The object directory
of the AMS 335
An object directory is structured such that some objects within a device profile (DS406 for
the AMS 335
turer-specific object area.
The objects are uniquely identified using an index addressing scheme. The structure of the
object directory, the assignment of the index numbers, as well as some mandatory entries
are specified in the CIA standard DS301 for CANopen.
Leuze electronic AMS 335i 55
i is the compilation of all process data and parameters of the AMS.
i) are mandatory while others are freely definable and stored in the manufac-
TNT 35/7-24V
CANopen interface
9.5.3 EDS file
For the user, the object directory of the AMS 335i is stored as an EDS file (Electronic Data
Sheet).
The EDS file contains all objects with index, sub-index, name, data type, default value,
minimum and maximum, and access privileges.
The EDS file describes the entire functionality of the AMS 335
9.5.4 SDOs and PDOs
The data exchange in CANopen distinguishes between service data objects (SDOs), which
are used for transmitting the service data (parameters) from and to the object directory, and
process data objects (PDOs), which are used to exchange the current process states.
9.5.4.1 SDOs
By using SDOs, all entries of the object directory can be accessed. Within one SDO call,
only one object can be accessed at any one time. For this reason, a service data telegram
must have a protocol structure which describes the exact target address by means of index
and sub-index addressing. SDO telegrams place a part of the SDO addressing into the user
data area. Eventually, a user data area with a width of 4 bytes out of the possible 8 bytes
of user data remains for each SDO telegram.
The target address always responds to SDO transfers.
In the following, the index and sub-index address of the AMS 335
can be found in the individual object descriptions.
9.5.4.2 PDOs
PDOs are a grouping of objects (variables and parameters) from the object directory. A
maximum of 8 bytes of user data from various objects can be mapped into one PDO.
A PDO can be received and evaluated by each participant (node). The model is referred to
as the producer-consumer procedure.
Since there is no protocol structure in the telegra m of a PD O, t he p articipants in the network
for whom these data are intended mu st k now how the use r da ta in the data area of the PDO
are structured (which data are stored where in the user data area).

56 AMS 335i Leuze electronic
CANopen interface
The exchange of process data is supported by the AMS 335i via the following accesses:
• Event-controlled data transfer
Here, the data of a node are transmitted as a message whenever a change to the present state occurs.
•Polling with remote frames
The CAN node which has been defined as master in the network requests the desired
information via query (via remote frame). The participant which has this information
(or the required data) responds by sending the requested data.
• Synchronized mode
CANopen permits simultaneous querying of inputs and states of different participants
and the simultaneous change of outputs or states. For this purpose, one uses the synchronization telegram (SYNC) transmitted by a master.
The SYNC telegram is a broadcast to all network devices with high priority and without
data content. Generally, the master sends the SYNC telegram cyclically.
Participants working in synchronized mode read their data when receiving the SYNC
message and then transmits them immediately afterwards as soon as the bus permits
this (see explanation regarding arbitration process).
As the SYNC process can very quickly lead to high bus loads, another distinction is
made between "event-controlled synchronization" and a "timer synchronization".
• Time-controlled transmission
In this case, the transmission of a PDO is triggered when an adjustable time period
has elapsed. The time-controlled transmissions are set individually for each PDO via
the so-called "inhibit time" or an "event timer". The respective parameters can be
found in the objects 1800h to 1803h for the corresponding PDOs.
• Node monitoring
Heartbeat and guarding mechanisms are available for failure monitoring of the
AMS 335
respond regularly in the event-controlled operating mode. In case of guarding, the participants are cyclically queried fo r their state via data request telegrams (remote frame).
In case of heartbeat, the nodes transmit their state themselves.
Heartbeat and guarding / life time are standard communication objects from the
DS301 CANopen specification. The corresponding objects here are:
- Heartbeat 1017
- Guarding / Life time factor 100Ch and 100D

9.5.5 Default 11 Bit - Identifier distribution
The AMS 335i sends an 11-bit identifier. 29-bit identifiers can neither be received nor transmitted by the AMS 335
The node address (address of the AMS 335
default identifier and the node address yield the COB-ID. Its value is used to determine the
prioritization during arbitration.
Notice!
Identifiers with low values have a higher priority under arbitration.
Example:
If the same objects, e.g. PD01 (rx), are queried by several AMS 335i in a CANopen network,
the AMS with the smallest node address has the highest priority under arbitration.
The table printed below shows the values of the individual functions in the CANopen arbitration process.
As can been see from the table, synchronization and emergency objects have the highest
priority. Next in line are the PDOs, and the SDOs have the lowest priority.

The AMS 335i provides four transmit process data objects (TPDOs).
The TPDOs describe which objects are mapped (integrated) into the TxPDO and define the
access (synchronous/asynchronous) to these objects.
• TPDO1 asynchronous position value and state, object address 1A00
• TPDO2 synchronous position value and state, object address 1A01
• TPDO3 asynchronous velocity value and state, object address 1A02
• TPDO4 synchronous velocity value and state, object address 1A03
The communication parameters of the PDOs are defined via fixed objects.
In these objects one specifies the synchronous or asynchronous access, a possible inhibit
time for the PDO object on the CAN network, and an event timer.
• PDO1 communication parameters for asynchronous position value and state, object
address 1800
h
• PDO2 communication parameters for synchronous position value and state, object

address 1803
h
The asynchronous transmission (TPDO1 and TPDO3) is controlled by the event timer in
PDOx property objects 1800h and 1803h.
The synchronous transmission (TPDO2 and TPDO4) is initiated via a SYNC telegram (80h)
sent by the master, and via PDOx property objects 1801h to 1803h.

Attention!
The inhibit timer can only be written to if the PDO has previously been set to "PDO invalid".
This is done by setting bit 31 of the COB-ID for the respective PDO to 1, setting the inhibit
time to the desired value, and then resetting bit 31 to 0 (=PDO valid). This applies to all 4
PDOs!

Sub-index 03 resolution
The resolution in mm or inch/100, in accordance with the unit selected.
The value for the free resolution must be set in index 06.
Sub-index 04 counting direction
Attention!
The DS406 encoder specification prescribes that the counting direction can be set in
object 6000 bit 3. Object 2000 sub-index 04 and object 6000 bit 3 overwrite each other.
The count direction changes the sign during velocity measurement.
A suitable offset is to be selected so that only positive values are transferred.
Counting direction positive:
Counting direction negative:
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.
66 AMS 335i Leuze electronic
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.
9.5.8.2 Object 2001h Static preset value
The static preset value is a parameter that is not changed after the handover of the system
to the end user. It is configured during commissioning and remains unchanged thereafter.
A preset value can be entered into the object. The preset value is activated with "preset
teach" and deactivated with "preset reset". After preset teach, the current position value is
offset against the configured preset value. After preset reset, the original measurement value
is displayed.

9.5.8.6 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 335i 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 335
i. When the reflector moves towards the AMS 335i, negative velocities are output.
68 AMS 335i Leuze electronic
CANopen interface
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.

9.5.8.7 Object 2021h Configuration velocity monitoring 1
Objects 2021h to 2024h permit the comparison between the current velocity as measured
by the AMS 335
Notice!
Notice regarding velocity monitoring 1 - 4 and dynamic velocity monitoring
If position start and position end are identical, velocity monitoring is not activated.
If a direction-dependent limit value check is activated via the direction selection parameter,
the values of position start and position end also define the direction. The check is always
performed from position start to position end. For example, if the range start is "5500"
and the range 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 irrel-
evant. 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.
Notice!
The explanations given above on the “Position start” and “Position end” parameters apply
analogously for objects 2022h through 2025h.

Notice
!
The sub-index 06 is available as standard, but functions only for devices with integrated heating (AMS 335
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.
