Note
• When the power of the Trajexia system is turned on, the TJ1-
MC__ executes its startup sequence before it initializes the
MECHATROLINK-II bus. During this startup sequence, the ML
COM LED is off.
• When the TJ1-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.
