4.4.5 Restarting Power Supplies and Checking Communication State
Download the parameters set by CMI to FP7 MC Unit, and then restart the power supplies for
the system (Unit and Servo Amplifier). The setting is reflected and the communication is
started.
PROCEDURE
1. Turn off the power supplies of FP7 MC Unit and Servo Amplifier A6B/A5B.
2. Turn on the power supply of Servo Amplifier A6B/A5B.
3. Turn on the power supply of FP7 MC Unit.
EtherCAT communication is started between Servo Amplifier A6B/A5B and FP7
MC Unit. Once the communication is executed and the link is established properly,
the both "EC RUN" LEDs turn on.
4. Confirm that no error occurs.
When an error occurs, the ERR LED on FP7 MC Unit turns on.
KEY POINTS
•
The connection state of the network can be checked by monitoring the unit
memories. The information on abnormal slaves is stored in the unit
memories (UM 0012E to UM 00139).
•
When the configuration is different from the network configuration set by
CMI, an error occurs.
•
The participation wait time for the nodes (slaves) connected to the
EtherCAT network can be set in the "MC common settings" menu of CMI
after the power-on of FP7 MC Unit.
