When Pr.549 Protocol selection = "1" (MODBUS RTU protocol), the setting range is as shown in the parentheses.
*2
When a value outside the setting range is set, the inverter operates at the initial value.
 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 connecting the inverter to the GOT2000 series using the RS-485 terminal block, set Pr.549 Protocol selection = "0 (initial
value) or 1".
• 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).
