Communication settings
Make the communication settings of the inverter.
Be sure to perform the inverter reset after updating
each parameter.
(1) Communication port and corresponding parameters
(2) Communication settings of inverter
• Set the following parameters using the PU
(parameter unit).
• After setting the parameters for the
communication settings, reset the inverter.
• Do not change these parameters, even though
they can be monitored from the GOT. If they are
changed, communication with the GOT is
disabled
*1 Setting items are parameter names described in the manual
of MELIPM series.
*2 Settings on the GOT can be changed.
When changing the settings on the GOT, be sure to change
the parameters on the inverter to correspond with the GOT
settings.
*3 Inverter default values (No need to change)
25.5.13 Station number setting
Set each station number so that no station number
overlaps.
The station number can be set without regard to the cable
connection order. There is no problem even if station
numbers are not consecutive.
(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.
