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).
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 FREQROL-E700 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)
