4. OPERATION

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. 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 15 for full information on the connection and transferred data between the controller and servo amplifier.

4.6.1 Positioning operation in accordance with programs

By selecting the program No. and switching on the forward rotation start (ST1) using the communication function, positioning operation in accordance with programs can be started.

(1)Selection of programs

Using the device forced output from the controller (command [9][2], data No. [6][0]), choose programs from among No.1 to 16.

4.6.2 Multidrop system

The RS-422 communication function can be used to operate several servo amplifiers on the same bus. In this case, set the station numbers to the servo amplifiers to determine the destination servo amplifier of the currently transmitted data. Use parameter No.15 to set the station numbers.

Always set one station number to one servo amplifier. Normal communication cannot be made if one station number is set to two or more servo amplifiers. When using one command to operate several servo amplifiers, use the group designation function described in Section 4.6.3.
