Question
Are there Inverters with RS-422A/485 communications?
Answer
Presently, the following models are capable of RS-422A/485 communications.
・ 3G3MV Series
・ 3G3RV Series
・ 3G3JV Series
Note:
In the 3G3JV Series, a 3G3JV-PSI485J RS-422/485 Communications Unit (sold separately) is required to support RS-422A/485 communications.
The communications protocol conforms to MODBUS communications protocol, so no other communications protocols can coexist with the MODBUS. Only Inverter-related products can be connected as Slaves.
Refer to the user's manual for details on the actual communications protocol.
