*1 Before configuring the automatic batch setting, if Pr.414 is set to 1, the setting is not changed.
(4) Communication settings of inverter (Manual setting)
Set the following parameters using the PU (operation panel or parameter unit). Before setting the parameters, set
Pr.160 (User group read selection) to 0 so that simple mode + extended parameters are displayed. (The default value
of FREQROL-F800 is 9999.)
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-A800, F800 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 Since the value has been set as a default, no setting is required when connecting to the PU connector on the inverter side.
*4 To use the FREQROL 800 driver, set 0.
*5 Inverter default values (No need to change).
*6 The inverter side setting defaults to 0 (invalid).
To use the PLC function, set 1 or 2.
