Examples of station number setting
(1) Direct specification
When setting the device, specify the station number of
the inverter 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
GD25).
When specifying the station No. from 100 to 155 on GT
Designer3, the value of GD10 to GD25 compatible to
the station No. specification will be the station No. of
the inverter.
