Node address setting
The node address of a servo amplifier is set according to Explicit Device Identification. Configure the settings
complied with Explicit Device Identification to the controller.
Do not connect several devices which have the same node address setting.
Set a node address in EtherCAT as necessary with ID setting switches (SW1/SW2) on the display, [Pr. NPA09 Node address
setting], or with SII Configured Station Alias. The node addresses are set as shown in the table below. After the node address
settings are changed, cycle the power.
Identifying slave stations with node addresses
There are following two methods for the controller to identify the slave station by using the node address.
• Identifying with AL Status Code (0134h)
The node address set with the ID setting switches (SW1/SW2) or [Pr. NPA09] can be read.
• Identifying with Configured Station Alias (0012h)
The node address set with SII Configured Station Alias can be read.
8.3
Network disconnection procedure
To disconnect the network when stopping the operation of equipment, follow the procedure shown below. Otherwise, [AL. 86.1
Network communication error 1] may occur.
1.
Stop the servo motor.
2.
Set the Shutdown command for [Controlword (Obj. 6040h)] to establish the servo-off state.
3.
Switch the state to the Pre-Operational state.
4.
Shut off the power of the servo amplifier and the controller.
