GOT2000 series automatic recognition
●
When the GOT2000 series is connected, the parameters required for the GOT connection are
automatically changed by setting the automatic recognition on the GOT2000 series side.
●
Set the station number (Pr. 117 or Pr. 331) of the inverter before the automatic recognition is
performed.
●
Connect all the stations of inverters with GOT before the automatic recognition is performed. The
inverter newly added after automatic recognition is not recognized automatically. (When an
inverter is added, perform the initial setting in Pr. 999 "Automatic parameter setting" or set the
automatic recognition on the GOT side again.)
