16.5.4 Station number setting
Set each station number so that no station number
The station number can be set without regard to the cable
connection order. There is no problem even if station
numbers are not consecutive.
Examples of station number setting
(1) Direct specification
When setting the device, specify the station number of
the servo amplifier of which data is to be changed.

(2) Indirect specification
When setting the device, indirectly specify the station
number of the inverter of which data is to be changed
using the 16-bit GOT internal data register (GD10 to
When specifying the station No. from 100 to 115 on GT
