QS2 Series Low Voltage Servo Drive
5.4 Custom Baud Rate
If you want to use custom baud rate, change the parameter P44. Below is the example
of the steps to change the baud rate of the drive from 9600 to 115200:
(1) The baud rate is 9600, port is COM3, communication is RS232, and
communication connection is OK.
(2) At this time, you can see P44 = 1 in P44 parameter "communication baud rate";
to change the baud rate to 115200, set this parameter to 7; other baud rates are
similar.
