PURPOSE: To control a motor controller without changing the hardware even in the case that the motor is different, by constituting CPU such that the control program sent from a communication interface can be written in the memory. CONSTITUTION: A host control unit 10 is connected to the CPU 77 and the EEPROM 1087 within a slave control unit 9 through a DP-ROM 79. Moreover, an external setter 26 is connected to the slave control unit 9, and a serial communication interface 72 is connected to the CPU 77 and the EEPROM 107, and a control parameter is stored besides the control program of a motor controller within the EEPROM 107. And, in the case that the object of control is exchanged, when new control program data are inputted, it is inputted into the DP-RAM 9 of the slave control unit 9 through the host control unit 10, and it is sent to the CPU 77, and is written into the EEPROM 107, and the data is updated. As a result, the control can be made without performing replacement of ROM, etc. |
