Connecting FREQROL-A700 series
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-A700 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)
*4
Since the value has been set as a default, no setting is required when connecting to the PU connector on the inverter side.

(1) Automatic setting with Pr.999
If Pr.999 is set as the following, the communication settings other than [PU communication
station number] and [Communication EEPROM write selection] can be automatically set in a
batch to the default communication settings of the GOT side.
*1
When monitoring the value of Pr.999, 9999 is always monitored.
(2) Inverters available for automatic batch setting
Parameters are not automatically set in a batch depending on the SERIAL (production
number) symbol of the inverter to be used. For details, contact your local distributor.
