(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.
