communications.
Note. If any of communication related error occurs while an error that is not related to MECHATROLINK-
II communications happens, the MECHATROLINK-II Communications Status LED Indicator
follows the corresponding communications status as shown above.
Turning on the Power Supply
Turn on the control circuit power after you conduct the pre-power-on checking.
You may turn on the main circuit power, but it is not a requisite.
It takes approx 2 seconds for the alarm output (/ALM) to turn on since the power-on. Do not
attempt to detect an alarm, during this period, by the Host Controller. This precaution relates to
the case when the power is turned on while the Host Controller is connected.
