 Automatic connection system configuration
 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 will not be 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.)

NOTE
• If the automatic recognition cannot be performed, initial setting in Pr.999 is required.
• For connection to a device other than the GOT2000 series, initial setting in Pr.999 is required.
• For details, refer to the GOT2000 Series Connection Manual (Mitsubishi Product).

5.15.10 Backup/restore

The GOT can be used for backing up inverter parameters and the data used in the PLC function of inverter.
The backup data stored in the GOT can be used to restore the data in the inverter.
