Yaskawa V7N Drive with DeviceNet - Manual (Page 14)

DeviceNet Indication LEDs
The V7N Embedded DeviceNet Drive has two ODVA standard DeviceNet LED’s on the cover to
indicate DeviceNet communications status.
The table below describes the function of DeviceNet specific LED’s.

Mismatch of baud rate.
Note: The LED’s will flash red once (100ms) during power up initialization. This is used in the internal testing process to
verify that the red LED is working properly.

MAC ID Setting Switch
The Drive’s MAC ID can be set in two different ways.
The MAC ID can be set using the rotary switches MSD (S3) and LSD (S4).
MAC ID = (MSD x 10) + LSD
Setting range of 0 to 63 on the rotary switches enables the rotary switches to set the Drive’s MAC ID.
Setting range of 64 to 99 on the rotary switches activates parameter n150 to set the Drive’s MAC ID.
Setting the MAC ID to 63 in conjunction with ADR enabled allows for some vendor’s “Faulted Node
Recovery” and the setting of the MAC ID through DeviceNet.
