Power-Up Diagnostics
An LED test is performed each time the drive is powered up. The initial boot sequence may take several seconds. After
the LEDs have completed the DeviceNet diagnostic LED sequence, the DeviceNet Option is successfully initialized. The
LEDs then assume operational conditions as shown in Table 3 .

Set the DeviceNet Option MAC ID
„
Parameter F6-50, MAC ID Setting
Range: 0~64
The MAC ID is set by drive parameter F6-50. A MAC ID setting in the range of 0~63 is considered a valid MAC ID. A
value other than 0~63 indicates the MAC ID is settable over the network.
The DeviceNet Option SI-N3 reads the MAC ID value from parameter F6-50 upon power-up and upon a network reset.
‹
Set the DeviceNet Option Baud Rate
The DeviceNet Option will support standard baud rates of 125 k bit/s, 250 k bit/s, and 500 k bit/s.

Auto Baud Rate Sensing (F6-51 = 4)
Setting parameter F6-51 = 4, "Auto Detect" causes the DeviceNet Option to determine the data rate of the DeviceNet
Network and configure itself appropriately.
Note: The auto baud capability will only be valid when there is more than one node physically on the DeviceNet network segment. The
drive digital operator will display “bUS” and the DeviceNet option LEDs will be (NS-OFF and MS=Solid Green) as long as auto
baud rate sensing fails to detect the baud rate.

Online communications
established
Device is on-line and has connections in the established state.
Green Flashing
Online communications not
established
Device is on-line but has no connections in the established state.
Dup Mac-ID test has been passed, is on-line but has no open
connections to other nodes.
Red ON Communications error
An error occurred that disables DeviceNet communications.
MAC ID duplication
Bus Off detected
Red Flashing Communications time-out A communications time-out occurred with the master.
Green/Red Flashing Communication faulted
Specific communication faulted device.
The device has detected a network access error and is in the
communications faulted state.
The device has then received and accepted an Identify communication
fault request-long protocol message.
