3) CC-Link communication error
A communication error is indicated by any of the following alarm/warnings.
At a servo alarm, the motor is stopped by the dynamic brake operated.
At a servo warning, the warning is displayed.
Check the MR-J2S-T01 unit LED states (refer to 6-1 LED On/Off) and remove the cause, or check the
CC-Link master station.
At error occurrence, receive data RX, RWw are all turned off or cleared to "0".
At CC-Link warning occurrence, normal communication is made.
