The Modbus communication port RJ45 (S+, S-) can be used to monitor, control, program and
trouble-shoot the inverter. The built-in RS-485 can support the following communication protocol:
Modbus communication protocol
BacNet communication protocol (Refer to section 4.7 for more details)
MetaSys communication protocol (Refer to section 4.8 for more details)
Pump in Parallel Connection (Refer to parameter group 23 for more details)
Modbus communication can perform the following operations, independent of the frequency command
selection (00-05) setting and operation command selection (00-02) setting:
