General Information on System Integration
4 General Information on System Integration
4.1 Using this Manual
This manual explains how to install and configure the photoelectric and magnetic absolute
rotary encoders with CANopen interface applicable for industrial applications with CANopen
interface.
Magnetic absolute rotary encoders are fully compliant with standard DS406.
Photoelectric absolute rotary encoders are fully compliant with following CiA standards:
■
DS301V402 CANopen Application Layer
■
DR303-1 Cabeling and connector pin assignment
■
DR303-3 CANopen indicator specification
■
DS305V200 CANopen Layer Setting Service
■
DS306V1R3 Electronic datasheet specification
■
DS406V32 Device Profile for Encoders
Measuring System for Photoelectric Absolute Rotary Encoders
The measuring system consists of a light source, a code disc pivoted in a precision ball bearing
and an opto-electronic scanning device. A LED is used as a light source which shines through
the code disc and onto the screen behind. The tracks on the code disk are evaluated by an
optoarray behind the reticle.
With every position another combination of slashes in the reticle is covered by the dark spots
on the code disk and the light beam on the photo transistor is interrupted. That way the code on
the disc is transformed into electronic signals. Fluctuations in the intensity of the light source
are measured by an additional photo transistor and another electronic circuit compensates for
these. After amplification and conversion the electronic signals are available for evaluation.
Measuring System for Magnetic Absolute Rotary Encoders
Magnetic rotary encoder determine positions using the Hall effect sensor technology
developed for the automotive mass market. A permanent magnet fixed to the shaft generates a
magnetic field that is sampled by the Hall sensor, which translates the measured value into a
unique absolute position value.
To register revolutions even when no voltage is applied, energy from the turning of the shaft
must suffice for proper operation. An innovative, patented technology makes this feasible even
at low rotational speeds and through long standstill periods – a Wiegand wire ensures that the
magnetic field can only follow the turning of the shaft in discrete steps. A coil wound on the
Wiegand wire receives only brief, strong voltage spikes, which prompt the reliable recognition
of each revolution.
Note!
Further information on technical data, mechanical data, connection layouts, and available
connection lines for the relevant absolute rotary encoder types can be found in the
corresponding datasheet.
4.2 General CANopen Information
CANopen system is used in industrial applications. It is a multiple access system (maximum:
127 participants), which means that all devices can access the bus. In simple terms, each
device checks whether the bus is free, and if it is the device is able to send messages. If two
devices try to access the bus at the same time, the device with the higher priority level (lowest
ID number) has permission to send its message.
12
2017-04
Absolute Rotary Encoder
General Information on System Integration
Devices with the lowest priority level must delay their data transfer and wait before retrying to
send their message. Data communication is carried out via messages. These messages
consist of 1 COB-ID followed by a maximum of 8 bytes of data. The COB-ID, which determines
the priority of the message, consists of a function code and a node number. The node number
corresponds to the network address of the device. It is unique on a bus. The function code
varies according to the type of message being sent:
■
Management messages (LMT, NMT)
■
Messaging and service (SDOs)
■
Data exchange (PDOs)
■
Layer Setting Services (LSS)
■
Predefined messages (synchronization, emergency messages)
The absolute rotary encoder supports the following operating modes:
■
Polled mode: The position value is only sent on request.
■
Cyclic mode: The position value is sent cyclically (regular, adjustable interval) on the bus.
■
SYNC mode: The position value is sent after a synchronization message (SYNC) is
received. The position value is sent every n SYNCs (n . 1).
Other functions (offset values, resolution, etc) can be configured. The absolute rotary encoder
corresponds to the class 2 encoder profile (DS 406 in which the characteristics of encoder with
CANopen interface are defined). The node number and speed in bauds are determined by
their corresponding object dictionary entries.
The transmission speed can range from 20 kBaud up to 1Mbaud (30 m cable for a maximum
speed of 1Mbaud, 1000 m cable for a maximum speed of 20 kbaud). Various software tools for
configuration and parameter-setting are available from different suppliers. It is easy to align and
program the rotary encoders using the EDS (electronic data sheet) configuration file provided
on the Pepperp+Fuchs internet page www.pepperl-fuchs.com

Installation of Photoelectric Absolute Rotary Encoder
5 Installation of Photoelectric Absolute Rotary Encoder
The following chapter describes all aspects helpful for installation of photoelectric absolute
rotary encoders with bus cover. Depending on the rotary encoder model there are the following
connection variants:
■
Rotary encoder with bus cover equipped with cable glands
■
Rotary encoder with bus cover equipped with a cable exit
■
Rotary encoder with bus cover equipped with one or two M12x1 connectors, 5-pin
Bus cover features like node number adressing, baud rate setting and activation of termination
resistor are identical for all these variants.
5.1 Signal Assignment of Terminal Block
The rotary encoder is connected with two or three cables depending on whether the power
supply is integrated into the bus cable or connected separately. If the power supply is
integrated into the bus cable, one of the cable glands can be fitted with a plug. The cable
glands are suitable for cable diameters from 6.5 up to 9 mm.

Bus Connection
The bus cover fulfills the function of a T-coupler. From there the wiring must be done according
to figure you find before. Please note the assignment of incoming and outgoing bus signals.
Caution!
Activated bus termination separates "Bus in" and "Bus out"
Non-observance of separation of "Bus in" and "Bus out" causes interferences on the CANopen
bus.
If you activate the bus termination on the rotary encoder ensure that the rotary encoder is the
last CANopen bus participant in the bus line.

Caution!
Activated bus termination separates "Bus in" and "Bus out".
Non-observance of separation of "Bus in" and "Bus out" causes interferences on the CANopen
bus.
If you activate the bus termination on the rotary encoder ensure that the rotary encoder is the
last CANopen bus participant in the bus line.
5.3 Activation of the Terminator
There is a terminator provided in the bus cover, which must be used as a line termination on the
last device. The terminator is switched on when the switch is in the "ON position" (see figure
before).
5.4 Installation Hints for Cabling
Cable Connection with Cable Gland
1. Remove screw, sealing and cone from the cable gland.
Figure 5.3
2. Remove 55 mm of the sheath and 50 mm of the shielding. About 5 mm of the wires should
be de-isolated.
3. Put screw and sealing on the cable.
4. The cone should be mounted under the shielding according to the figure before. Put the
whole cable into the cable gland and tighten the screw.
Minimization of Signal Interferences
Both the cable shielding and the metal housings of rotary encoders and subsequent
electronics have a shielding function. The housing must have the same potential and be
connected to the main signal ground over the machine chassis or by means of a separate
potential compensating line. Potential compensating lines should have a minimum cross
section of 6 mm
Do not lay signal cable in the direct vicinity of interference sources (air clearance > 100 mm (4
in.))
A minimum spacing of 200 mm (8 in.) to inductors is usually required, for example in switchmode power supplies.
Configure the signal lines for minimum length and avoid the use of intermediate terminals.
Shielded fieldbus cables shall be used! The shield must be grounded according to EMI rules!
In metal cable ducts, sufficient decoupling of signal lines from interference signal transmitting
cable can usually be achieved with a grounded partition.

6.2 Activation of Terminator
Note!
The magnetic absolute rotary encoder is equipped with an internal terminator, which can be
used as a line termination. Be aware, that the terminator is only activated, when the encoder is
powered, because the microcontroller is internally needed to switch on the terminator.
If the rotary encoder is connected at the end or beginning of the bus using of the internal
terminator is possible by parameterization of SDO object "3002 h" The internal terminator is
acitvated by writing "01 h" into this object.
6.3 Setting of Node Number and Baud Rate
Setting of the node number and baud rate has to be done by parameterization of the relevant
SDO objects or via LSS. Some absolute rotary encoders are provided with auto baud detection
(see relevant datasheet).
Default values are:
■
Baud rate 125 kBaud
■
Node number 32 decimal (20 h)
Setting Node Number via SDO Objects
The node number has to be adjusted via SDO objects. To set the node number, object 3000h
has to be written. For further information regard chapter "Object Descriptions".
Setting Baud Rate via SDO Objects
The baud rate has to be adjusted via SDO objects, if auto baud feature is not activated or is not
possible to use because of network start-up behavior. To set baud rate object 3001h has to be
written. For further information regard chapter "Object Descriptions".

Absolute Rotary Encoder
Quick Start Guide
7Quick Start Guide
Intention of this chapter is to help the user getting a magnetic or photoelectric absolute rotary
encoder very easy and fast to operate. The user is still responsible to configure the absolute
rotary encoder in the right way and reading the whole manual carefully.
With the following sequence a normal procedure is described to configure a device for
standard applications. It shall guide you roughly through this process.
7.1 Configure the Absolute Rotary Encoder for Integration into a CAN Network
For this purpose you need to set up the node number and the baud rate first.
Depending on your absolute rotary encoder model there are different ways to do so.
■
Photoelectric absolute rotary encoder with bus cover: Setting is possible via BCD coded
rotary switches or if rotary switch Bd = 9 via SDO objects or Layer Setting Services (LSS).
■
Magnetic absolute rotary encoder: Default setting for node number is 32 decimal and
baud rate is 125 kBaud. If other settings are required setting is only possible via SDO
objects or Layer Setting Services (LSS). Some models have auto baud rate detection (see
relevant datasheet) which has to be checked if activated. If this feature is activated so only
node number has to be set.
Caution!
Check requirements of baud rate and node number of your network before configuration!
If your running network uses a different baud rate or the node number is already in use, then
you shall make a point-to-point connection to the encoder with a configuration tool to prevent a
crash of the different configured running network. If auto baud feature is used in the encoder it
simplifies installation.
First Steps of Configuration of a Magnetic Absolute Rotary Encoder
1. If the encoder has no active auto baud detection connect the encoder with a configuration
tool and set the baud rate to 125 kBd.
2. Power on the encoder.
You will see a boot up message in case of a trace tool is used. For devices equipped with
status LEDs a green colored LED is blinking to indicate the CAN state PREOPERATIONAL.
3. If necessary activate the terminator of the encoder by writing "01h" into object "3002 h".
4. Continue by reading and writing data into the relevant following objects in this chapter.
First Steps of Configuration of a Photoelectric Absolute Rotary Encoder
Note!
In case you want to set baud rate and node number via SDO objects rotary switch Bd has to be
in position 9.
1. Set the baud rate desired with rotary switch Bd (20 kBd factory default) and the node address you need with rotary switches x10 and x1 (32 factory default) . If Bd = 9 connect the
encoder with a configuration tool and set the baud rate desired.
2. Power on the encoder.
You will see a boot up message in case of a trace tool is used. For devices equipped with
status LEDs a green colored LED is blinking to indicate the CAN state PREOPERATIONAL.

7.2 Configure application-specific encoder Parameters
For adaption of the encoder in your application you may use objects to configure the resolution
per revolution and the total resolution. Especially the preset value is relevant to adjust the
position value of the encoder to a desired value in the machine after mechanical installation. It
is useful to store the configuration in the device and not to re-configure the different parameters
after each power cycle or NMT reset. In the following tables the new configured node number is
assumed.

operation during standstill of the encoder shaft to increase the accuracy, because the device is
calculating itself an offset value. If you set the preset dynamically, which is not recommended,
then you have also to take bus latency time into consideration and encoder internal cycle time.

8 Configuration
The following chapter describes the configuration of photoelectric and magnetic absolute
rotary encoders with CANopen interface.
8.1 Operating Modes
8.1.1 General
The rotary encoder accesses the CAN network after power-up in preoperational mode: Bootup
message: 700 hex + node number
It is recommended that the parameters can be changed by the user when the rotary encoder is
in pre-operational mode. Pre-operational mode entails reduced activity on the network, which
simplifies the checking of the accuracy of the sent/received SDOs. It is not possible to send or
receive PDOs in pre-operational mode.
8.1.2 Mode: Pre-operational
To set a node to pre-operational mode, the master has to send the following message:
Identifier Byte 0 Byte 1 Description
0h 80h 00h NMT-PreOp, all nodes
0h 80h NN NMT-PreOp, NN
Ta b l e 8 . 1
NN: node number
It is possible to set all nodes (Index 0) or a single node (Index NN) to pre-operational mode.
8.1.3 Mode: Start - Operational
To put one or all nodes in the operational state, the master has to send the following message:
Identifier Byte 0 Byte 1 Description
0h 01h 00h NMT-PreOp, all nodes
0h 01h NN NMT-PreOp, NN
Ta b l e 8 . 2
NN: node number
It is possible to set all nodes (Index 0) or a single node (Index NN) to pre-operational mode.
8.1.4 Mode: Stopped
To put one or all nodes in the stopped state, the master has to send the following message:
Identifier Byte 0 Byte 1 Description
0h 02h 00h NMT-PreOp, all nodes
0h 02h NN NMT-PreOp, NN
Ta b l e 8 . 3
NN: node number
It is possible to set all nodes (Index 0) or a single node (Index NN) to pre-operational mode.
8.1.5 Reinitialization of the Rotary Encoder
If a node is not operating correctly, it is advisable to carry out a reinitialization:

current process value. If more than one node number (encoder) shall answer
after receiving a sync telegram, the answer telegrams of the nodes will be
received by the host in order of their node numbers. The programming of an
offset-time is not necessary. If a node should not answer after each sync
telegram on the CAN network, the parameter sync counter can be
programmed to skip a certain number of sync telegrams before answering
again.

Note!
The stored parameters are copied after a RESET (Power on, NMT-Reset) from the E
the RAM (volatile memory).
Storing without Reset
By using the object 1010h from the communication profile-related object dictionary you can
store the parameters into the non-volatile memory without a reset.
Sto ring with Reset
By using the object 2300h from the manufacturer-specific object dictionary you can store the
parameters into the non-volatile memory. After storing the parameters a reset of the device is
performed.
8.4 Restoring Parameters
The default parameters can be restored by using the object 1011h from communication profilerelated object dictionary. The already in the non-volatile memory programmed parameters are
not overwritten. Only after a new store command the default parameters are stored in the nonvolatile memory. To restore the default parameter the following telegram is used. The restored
parameters are equal for every type of CANopen encoder and might not fit with the status after
delivery. Please check the restored parameters before you store them to the non-volatile
memory.

8.5 Usage of Layer Setting Services (LSS)
LSS with photoelectric rotary encoders
The integrated Layer Setting Service functionality is designed according to the CiA normative
DS305V200 CANopen Layer Setting Service: General Description: These services and
protocols can be used to inquire or to change settings of several parameters of the physical,
data link layer, and application layer on a CANopen device with LSS slave capability by a
CANopen device with LSS master capability via the CAN network. In case of the OCD-II-series,
the encoder will be the LSS slave device and the PLC (control) has to support LSS master
device functionality. The LSS-functionality of the OCD-II-series is limited to the following
parameters of the application layer, namely node number and baud rate.

Ta b le 8. 6
The LSS master device requests services that are performed by the encoder (LSS slave
devices). The LSS master device requests the LSS address from the LSS slave device. The
LSS address is defined in object 1018h Identity Object - it consists of vendor-id, product-code,
revision-number and serial-number as shown in Table 10. After receiving this information the
control can unequivocally identify the encoder and the node number and baud rate can be set.
The exact procedure varies in detail, coursed by the different PLC tools.

To configure the encoder via LSS the encoder will be the LSS slave device and the control has
to support LSS master device functionality. The LSS master device requests services, that are
performed by the LSS slave devices (encoder). The LSS master device requests the LSS
address (vendor-id, product-code, revisionnumber, serial-number) from the LSS slave device.
After receiving this information the control can unequivocally identify the encoder and the node

Inhibit Time
For "Transmit PDOs", the "inhibit time" for PDO transmission can be entered in this 16-bit field.
If data is changed, the PDO sender checks wether an "inhibit time" has expired since the last
transmission. A new PDO transmission can only take place if the "inhibit time" has expired. The
"inhibit time" is useful for asynchronous transmission (transmission mode 254 and 255) to
avoid overloads on the CAN bus.
Event Timer
The "event timer" only works in asynchronous transmission mode (transmission mode 254 and
255). If the data changes before the "event timer" expires, a temporary telegram is sent. If a
value > 0 is written in this 16-bit field, the transmit PDO is always sent after the "event timer"
expires. The value is written in subindex 5 of a transmit PDO. The data transfer also takes place
with no change to data. The range is between 1 - 65536 ms.

Ta b l e 9 . 5 1
By writing 01h to this object the internal galvanic isolated terminator is activated.
Note!
Note that the terminator is only activated when the device is powered. If you have more CAN
nodes on the bus be sure to power them approx. 700ms after the device with the programmed
terminator. Otherwise reflections could occur and network quality is probably reduced.
9.5.39 Object 3003h: Auto Baud Detection
This object controls the baud rate measurement of the device after power-up or NMT reset.
With this feature the user can add the encoder to a network without knowing the baud rate. Just
the specified baud rates in CANopen are supported and also 100 kBbd as listed in object
3001h baud rate.
If the auto baud detection is enabled, then after power-up the encoder is just listening to the
network and tries to identify within the Time Out (3003h, 2h) a valid CAN message. When this
is done successfully, then the device is sending the boot up message and enters the preoperational state.

Boot up
For devices with LED in the M12 connector the active auto baud mode is indicated by flickering
alternative a red and green LED.

Reason for non successful baud rate detection
■
Time out: Within the time-out period no valid CAN message is sent.
Corrective action: increase the time-out value to a value that for minimum 1 message is
sent or better more. Check, if power-up time of the other devices is synchronously
switched on like for the encoder. Perhaps you have to take this different power-up time
also into consideration.
■
EMC effects: If a non valid CAN frame is detected, then the encoder retries to measure a
valid CAN frame within the time-out period.
Corrective action: check the shielding of the cables, connections, termination in the CAN
network. If no improvement is realized, then deactivate temporary the auto baud detection
and set the baud rate by use of object 3001h. Then further investigations are possible to
find the root cause in combination with a trace tool.
■
Errorframes: Disturbances in the CAN network communication.
Corrective action: Find the communication problem in the network by selective use of
nodes and consecutive adding further one.
Reaction in case of non-successful baud rate detection
When the baud rate can’t be measured within the time-out period, then the encoder is using the
last "known" baud rate:
■
If the encoder is used out of the box, then the value is 125 kBbd.
■
If the encoder was already in use, then the last successful baud rate is stored
automatically in object 3001h and taken in this case.

9.5.46 Object 3040h: Life Cycle Counter
Diagnostic value to monitor, if the position value is updated compared to last transmission. This
feature is interesting for safety applications to detect for example, if the value in the CAN
controller is frozen. The value starts at power up with 0 and is continuously incremented. When
overflow is reached, then it starts again with 0. It is not expected, that the transmitted value is
incremented, because the life cycle counter is handled in the function when the position value
is measured and this process is asynchronous to the CAN communication.

Restart encoder so the
new baud rate setting will
be valid.
Check, if the last bus node
has switched on the
terminator.
Check if all bus node has the
same baud rate. If one node
has another baud rate error
frames are produced
automatically.
The limit switch functionality
has to be activated once.

Note!
Baud rate and node number changes
The changing of baud rate and node number are only valid after a new power-up, NMT Reset or
the store parameters command.
