Automatic Connection With Got - Mitsubishi Electric 800 Series Instruction Manual

5.15.8

Automatic connection with GOT

When the automatic connection is enabled in the GOT2000 series, the inverter can communicate with the GOT2000
series with only setting the station number and connecting the GOT. This eliminates the need for the communication
parameter setting.

When Pr.549 Protocol selection = "1" (MODBUS RTU protocol), the setting range is as shown in the parentheses.

When the set value is outside of the setting range, the initial value is applied.
Automatic connection system configuration
GOT2000
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 Electric Product).
