Note
•
When the power of the Trajexia system is turned on, the
TJ2-MC__ executes its startup sequence before it initializes
the MECHATROLINK-II bus. During this startup sequence, the
ML COM LED is off.
•
When the TJ2-MC__ initializes the MECHATROLINK-II bus
with the command
MECHATROLINK(unit,0)
, the ML COM
LED goes on.
•
When the GRT1-ML2 loses the MECHATROLINK-II communi-
cation with the master, or when the command
MECHATROLINK(unit,1)
is executed, the ML COM LED goes
off.
