2. When MODBUS communication protocol is used to communicate with outside, no
more than 31 inverters can be connected in parallel. If multiple inverters are
connected, a resistor of 220Ω must be connected to both sides of the RS-485 COM
port of the last inverter.
3. Please refer to "A510 RS-485 MODBUS communication function application
manual."
b. Wiring example of PROFIBUS communication protocol
‧ A PROFIBUS model (JN5-CM-PDP) requires to be added for the
communication of PROFIBUS-DP.
