User Manual of A90 Series Inverter During the communication based on the Modbus-RTU protocol, the A90 series inverter supports six different baud rates in bps (bit/s). Take F10.01=9600bps as an example. It means that data is transmitted at a rate of 9600bits per second. By default, each byte consists of valid 8-bit data (such as 0x01). When 10-bit data needs to be transmitted in the actual situation, the transmission time is about 1.04ms (approximately 1.04167ms=10bit/9600bps). default), check bit (optional), and a stop bit.
The A90 series inverter supports six data In the UART transmission, the data usually consists of a start bit, valid data (8 bits by formats according to the Modbus-RTU combinations in communication. If F10.02=0, it means that the current data consists of one start bit + eight data bits + no check bit + one stop bit. ★ N (NONE): no parity; E (EVEN): even parity; O (ODD), odd parity. 210 Function code Function code Default Parameter description Unit Attribute name setting F10.01 Baud rate of Modbus communication 0:4800 1:9600 2:19200 3:38400 4:57600 5:115200 bps 1 ○ Function Function Default Parameter description Unit Attribute code code name setting F10.02 Modbus data format 0:
