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.

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.

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.

Absolute Rotary Encoder

General Information on System Integration

2017-04

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.

5.2 Signal Assignment of Connector and Cable Variants

The rotary encoders with cable- and connector-exit were designed in accordance to CiA

normative DR303-1 cabeling and connector pin assignment. They also have a removable bus

cover with all possibilities to set node number, baud rate and acitvate terminator.

Figure 5.2

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 switch-

mode 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.

5.5 Setting of Node Number and Baud Rate in the Bus Cover

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.

Note!

Setting of node number and baud rate has to be done via software if Bd rotary switch is set to 9.

SDO objects and Layer Setting Services (LSS) are provided for this purpose.

Setting Node Number

The setting of the node number is done by turning the BCD coded rotary switches x10 and x1

in the bus cover. Possible (valid) addresses lie between 0 and 89 whereby every address can

only be used once.

Figure 5.4

Possible device address 0 ... 89.

Addresses 90 ... 99 are reserved.
