1.3 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.

Page 22

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.

5.2.2 Parallel mounting of the AMS 338i

Reflector 1 Reflector 2

Definition of the term "parallel spacing"

As shown in figure 5.4, dimension X describes the "parallel spacing" of the inner edges of the two laser light spots on the reflector.

Figure 5.4: Minimum parallel spacing X between adjacent AMS 338i

The diameter of the light spot increases with distance.

AMS 338i 40 (H) AMS 338i 120 (H) AMS 338i 200 (H) AMS 338i 300 (H)

Installation and mounting

Max. measurement distance Light spot diameter ≤ 40mm ≤ 100 mm ≤ 150 mm ≤ 225mm

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.

40m 120m 200m 300m

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 120 m: minimum parallel spacing X ≥ 600 mm

Measurement distance up to 200 m: minimum parallel spacing X ≥ 750 mm

Measurement distance up to 300 m: minimum parallel spacing X ≥ 750 mm

Installation and mounting

The reflectors are mounted stationary and in parallel on one plane. 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 100 mm to the AMS 338i. The parallel spacing is independent of the distance.

5.3 Mounting the AMS 338i with laser beam deflector unit

General information

The two available deflector units are used for the 90° deflection of the laser beam, see "Accessory deflector unit" on page 85.

Attention!

The deflector units are designed for a maximum range of 40m. Longer distances on request.

5.3.1 Mounting the laser beam deflector unit With integrated mounting bracket

The AMS 338i is screwed onto the mechanism of the US AMS 01 deflector unit. The mirror can be mounted for three deflection directions:

1. Upward beam deflection

2. Beam deflection to the left

3. Beam deflection to the right

The deflector unit is mounted on plane-parallel, flat walls or plant components. For errorfree position measurement, there must be an interruption-free line-of-sight between the AMS 338i… and the deflection mirror as well as between the mirror and the reflector.

Use the M5 screws to mount the deflector unit. Secure the screws with a toothed lock washer to protect against loosening caused by vibrations.

6.1 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.

6.2.4 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.

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 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.

Reflectors

6.4 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 2 m-long connection cable for supplying with 230V AC. 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 M 12 connections are on the side, the "TOP" label of the reflector is also on the side.

Note regarding the second station address - in short SSA- (formerly station alias)

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

Display and control panel AMS 338i

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.

9 EtherCAT interface

9.1 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.

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.

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.

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.

9.4 EtherCAT – Cable lengths and shielding

ferred, 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.

Leuze electronic AMS 338i 53

Use CAT 5 cable for the connection.

Notice!

For the AMS 338i as standalone device or as the last participant in a linear topology, termination on the BUS OUT socket is not mandatory!

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.

9.7 CANopen over EtherCAT

EtherCAT provides the communication mechanisms described below. In this context, the SDO accesses to the online dictionary via CoE (CANopen over EtherCAT) are carried out via mailbox services. PDO services via CoE mailboxes are not supported.

• Object index

• PDO, process data object

• SDO, service data object

•NMT, network management

Master and slave must be located in the same EtherCAT network.

9.7.1 Device profile

The device profile describes the application parameters and the functional behavior of the AMS 338i. For EtherCAT, one does not specify individual device profiles for device classes. Instead, simple interfaces for existing device profiles are provided.

The AMS 338i supports the DS406 "device profile for encoder" already known from CANopen.

9.7.2 Device description file

For the user, the object directory of the AMS 338i is stored in a so-called ESI file (EtherCAT slave information).

The ESI file contains all objects with index, sub-index, name, data type, default value, minimum and maximum, and access privileges.

The ESI file describes the entire functionality of the AMS 338i.

The ESI file has the name AMS 338i.xml and is available for download on the Leuze home page www.leuze.com.

100m

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.

A suitable offset is to be selected so that only positive values are transferred.

Counting direction positive:

+100m

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.

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.

9.7.6.7 Object 2021h Configuration velocity monitoring 1

Objects 2021h to 2024h permit the comparison between the current velocity as measured by the AMS 338i and a limit stored in the respective object.

Notice regarding velocity monitoring 1 - 4 and dynamic velocity monitoring

If range start and range 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 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 2026 set via object 2050

0 = Standard (10°C … 15°C) 1 = Extended (30°C … 35°C)

Notice!

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.
