(2) The inverter is a master in the network, the slave will not response to the command sent by the inverter via broadcast
address.
(3) Users can set the inverter’s current address, baud rate and data format by using the inverter’s keypad or through the
serialcommunication port.
(4) The drive can report the current fault information when polled by the master.
