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 the EtherCAT node address with ID setting switches (SW1/SW2) on the display, [Pr. NPA09 Node address setting], or SII
Configured Station Alias depending on the situation. The node addresses are set as shown in the table below. After the node
address settings are changed, cycle the power.
ID setting switches [Pr. NPA09]
(SW1/SW2)
00h 00000000h
00h 00000001h to 0000FFFFh
01h to FFh 00000000h to 0000FFFFh
Identifying slave stations with node addresses
There are following two methods for the controller to specify the slave station by using the node address.
• Specifying with AL Status Code (0134h)
The node address set with the ID setting switches (SW1/SW2) or [Pr. NPA09] can be read.
• Specifying with Configured Station Alias (0012h)
The node address set with SII Configured Station Alias can be read.

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.
SII Configured Node address setting value
Station Alias
0001h to FFFFh The value set in SII Configured Station Alias via network is the node
address.
0000h The value in [Pr. NPA09] is the node address.
0000h The setting value of the ID setting switches (SW1/SW2) is the node
address.
