Parameter F6-50 sets the option MAC ID. MAC ID settings between 0 to 63 are valid MAC IDs; setting 64
identifies a network-settable MAC ID.
The option reads the MAC ID value from F6-50 upon power-up and upon a network reset.
◆
Communication Speed
Parameter F6-51 [DeviceNet Baud Rate] sets the option baud rate. The option supports standard baud rates of 125
kbps, 250 kbps, and 500 kbps.

500 kbps 2
Adjustable from Network 3
Detect Automatically 4
■
Auto Baud Rate Sensing (F6-51 = 4 [DeviceNet Baud Rate = Detect Automatically])
Set F6-51 = 4 [DeviceNet Baud Rate = Detect Automatically] to enable automatic baud rate detection and to
allow the option to automatically determine the baud rate of the DeviceNet network.
Note:
Auto baud rate sensing is valid only when there is more than one node physically on the DeviceNet network segment. If the auto baud
rate sensing does not detect the baud rate, the drive keypad will show
“ bUS ” and the option LEDs will be OFF (NS) and solid green
(MS).

EDS Files
For easy network implementation of drives equipped with the option, an EDS file can be obtained from:
U.S.: http://www.yaskawa.com
Europe: http://www.yaskawa.eu.com
Japan: http://www.e-mechatronics.com
Other areas: Check the back cover of these manuals.
For questions, contact Yaskawa or a Yaskawa representative.
Note:
Download the EDS file for SI-N3 option. The SI-N3 will not function as a slave in the network without the appropriate EDS file.

Note:
• To start and stop the drive with the DeviceNet master device using serial communications,
set
b1-02 = 3 [Run Command Selection 1 = Option PCB] or set the Net Control bit in the
assemblies or Control Supervisor Object. To control the frequency reference of the drive via
the master device, set
b1-01 = 3 or set the Net Reference bit in the assemblies or AC/DC
object.
• The default setting is different for different drives. Refer to the instruction manual of your
specific drive for more information.
