15. COMMUNICATION FUNCTION
15.2.2 Parameter setting
When the USB/RS-422 communication function is used to operate the servo, set the communication
specifications of the servo amplifier in the corresponding parameters.
After setting the values of these parameters, they are made valid by switching power off once, then on again.
