EtherCAT Communication Unit USER’S MANUAL (3G3AX-MX2-ECT)
These switches are used to set the node addresses of slaves in the EtherCAT network (decimal).
The 10s digit is set on the left rotary switch and the 1s digit is set on the right rotary switch.
The setting range is 00 to 99.
Note that the node address settings vary as shown below when the Host Controller is made by OMRON
and when it is made by other manufacturers.
• The set node address is read only once when the inverter power supply is turned ON.
If the setting is changed after the power supply is turned ON, the new setting will not be used
until the next time that the power is turned ON.
• Do not change the setting on the rotary switches after the power supply has been turned ON.
• If node addresses overlap, an error occurs and the operation stops.
