5.2 Encoder installations configuration of node parameters
LSS address
Each sensor (node) in the CAN network is defined unique by the
LSS address. This address consists of:
Vendor-ID: 0x40
Product Code: 0x43333034 (C304)
Revision No.: 0x00010001
Serial No.:
04301234
CANbus specific parameters like baud rate and node address
(node ID) can be configured and recorded by LSS service routines.
Configure baud rate
The maximum baud rate depends on the cable length of the total CAN
network. The sensor is shipped with an order dependent baud rate, as
printed on the sensor label. If necessary, the baud rate can be changed
via LSS service.
Cable length
Baud rate
< 25 m (82 ft.)
1000 kBit/s
< 50 m (164 ft.)
800 kBit/s
< 100 m (328 ft.)
500 kBit/s
< 250 m (820 ft.)
250 kBit/s
Table 1: Baud rate according to cable length (see CiA DS 301)
Configure node ID
Each node gets a node identifier (node ID) for identification in a
CANopen network. Each node ID can be assigned only once in
a CAN network. Valid node IDs range is from 1…127, with 127
being the default setting on delivery.
Bus termination
The internal bus termination resistor with 120 Ω is not attached but
can be ordered as an additional option (output option).
EDS file
The EDS file is the standardized format for the description of devices.
It contains information about:
• File properties (name, version, release date,…)
• General device information (manufacturer name and code)
• Device name and type, version, LSS address
• Supported baud rates and boot-up options
• Description of supported objects and attributes
5.3 Configuration of process parameters
The sensor starts up using the parameters stored in its internal
EEPROM; the user can change and/or permanently store settings
using SDO uploads as desired. Please be aware that in case the node
ID is changed using LSS, the identifiers for PDOs etc. will be changed
accordingly.
The sensors implement the encoder communication profile “Device
Profile for Encoder – DS 406 V3.1”. In the following object dictionary
the programming of the operating parameters is described.
NOTICE
Program the baud rates according to the LSS protocol.
Note the parameters given in table 1.
