■Identifying slave stations with node addresses
The controller can identify slave stations by the node address using AL Status Code (ESC register: 0134h) or Configured
Station Alias (ESC register: 0012h). Identify the slave stations by using either code.

• Identifying with AL Status Code (ESC register: 0134h)
Set the node address with the ID setting switches (SW1/SW2) or [Pr. NPA09] by referring to the following table. Set the master
station using AL Status Code (ESC register: 0134h) so that the node address is recognized.
When using [Pr. NPA09] for the node address, set the ID setting switches (SW1/SW2) to "00h".
When using the ID setting switches (SW1/SW2) for the node address, the value set in [Pr. NPA09] is not reflected in the node
address.

• Identifying with Configured Station Alias (ESC register: 0012h)
Write the value of the node address to SII Configured Station Alias (ESC register: 0012h) from the master station (controller).
The node address is saved on EEP-ROM. Set the master station so that SII Configured Station Alias (ESC register: 0012h) is
recognized as a node address.
Mapping settings
When mapping objects that transmit command data and feedback data using PDO communication, perform the settings via
the controller.
For information regarding the default mappings of the servo amplifier, refer to the following section.
Page 15 PDO default mapping
Communication setting
For settings related to communication between the controller and servo amplifier, perform the settings via the controller. For
information regarding settable communication cycles, refer to the following section.
Page 9 Communication specifications
For the servo amplifier, synchronous mode (DC mode) and asynchronous mode (FreeRun mode) can be set. Set the mode
that is appropriate for the application.
