 MECHATROLINK-II Status LED Indicator
The display status of the MECHATROLINK-II status LED indicator (COM) is described below.
Note If a communications error occurs at the same time as a non-communications error, the
MECHATROLINK-II status LED indicator (COM) will still follow the above rule.
Turning ON Power
 First carry out the preliminary checks, and then turn ON the control-circuit power supply.
It makes no difference whether or not the main-circuit power supply is turned ON.
 The alarm (/ALM) output will take approximately 2 seconds to turn ON after the power has been
turned ON. Do not attempt to detect an alarm using the Host Controller during this time (if power
is turned ON while the Host Controller is connected).
