PROBLEM TO BE SOLVED: To realize communication between an RS232C communication medium and a servo amplifier and multidrop communication to the plural servo amplifiers by RS422 (RS485) without, the need of a private conversion device in a multiaxis driving control system. SOLUTION: An RS232C communication I/F circuit 21, an RS422 (RS485) communication I/F circuit 22 and CPU 11 are installed in a servo amplifier 10. Data received by the RS232C communication I/F circuit, 21 is taken into a self-station with a processing operation by CPU 11 and received data is converted into communication data for RS422 (RS485). It is transmitted to the other station from the RS422 (RS485) communication I/F circuit 22. On the other hand, data received by the RS422 (RS485) I/F circuit 22 is converted into communication data for RS232C and it is transmitted to the other station from the RS232C communication I/F circuit 21.
