    10. Communication Protocal 10.1 Communication Mode 1．Inverter communication protocol is Modbus protocol, and supports the common register read and write。 2．Drive as a slave, master-slave point to point communication. A Master drive uses broadcast address to send a command, the slave does not answer. 3．In the case of long distance or multi-machine communication, we recommend to connect the the master station signal GND with the drive signal "GND", in order to improve the communication of immunity...
