Operation
Checking the EtherCAT Communications Connectors
 The EtherCAT Communications Cables must be connected securely to the EtherCAT
Communications Connectors (ECAT IN and ECAT OUT).
Checking the Node Address Setting
Make sure that the node address is correctly set on the node address rotary switches.
Precautions for Correct Use
 Do not change the setting on the rotary switches after the power supply has been turned ON.
 The node address rotary switches can be set to between 00 and 99.
The node address used over the network is determined by the value set on the rotary switches.
If the node address is not between 00 and 99, a Node Address Setting Error (Error 88.0) will occur.
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 required.
