IF55 ROT CANopen®

6 - CANopen® interface (DS 406)

CANopen® converters for SSI encoders are always Slave devices and comply
with the “Device profile for encoders”, Class 2.
For any omitted information concerning the CANopen protocol, refer to the “CiA
Draft Standard Proposal 301. Application Layer and Communication Profile” and
to the “CiA Draft Standard Proposal 406. Device profile for encoders” documents
available at the address

www.can-cia.org

6.1 EDS file

CANopen® converters are supplied with their own EDS file

Lika_IF55_ROT_DS406_Vx.eds

, see at

www.lika.biz > DISPLAYS &

INTERFACES > SIGNAL CONVERTERS & INTERFACES (POSICONTROL)

EDS file is available in both English (

Lika_IF55_ROT_DS406_Vx_en.eds

) and

Italian (

Lika_IF55_ROT_DS406_Vx_it.eds

) versions.

Vx is intended to indicate the file version.
EDS file has to be installed in the CANopen® Master device.
Please note that the rotary encoder converters and the linear encoder
converters have different EDS files. Files for rotary encoders are marked with
-ROT- in the file name; while files for linear encoders are marked with -LIN- in
the file name.

6.2 State machine

CANopen® devices are designed to operate using different states. Transition
from one state to another is made by sending specific NMT messages (see the
Figure below).

(1)

Power on

(2)

Initialization carried out, boot-up message is sent automatically

(3)

NMT message:

Start remote node

(4)

NMT message:

Enter pre-operational
