The followings take the accumulate sum check mode as an example to explain complex command
protocol.
Send FWD running command to No.1 slave and set running frequency to 30.00Hz
Send deceleration stop command to No.1 slave and set running frequency to 0.00Hz
No.1 slave responds to the host: the inverter is FWD running at present and the actual running
frequency is 25.00Hz
No.1 slave responds to the host: the inverter is FWD running at present and the actual running
frequency is 30.00Hz
