4.6 Serial communication operation
The RS-422 or RS-232C communication function may be used to operate the servo amplifier from a
command device (controller) such as a personal computer. Positioning operation can be performed with
the positioning operation/position specified by selection of the point tables. Note that the RS-422 and RS-
232C communication functions cannot be used at the same time.
This section provides a data transfer procedure. Refer to Chapter 8 for full information on the connection
and transferred data between the controller and servo amplifier.
