PURPOSE:To perform interruption control over respective shafts independently of one another by incorporating plural interruption input circuits in a control part corresponding to the respective shafts, interrupting the movement of only a shaft corresponding to an interruption input circuit, and providing an interruption processing part corresponding to a shaft expected to execute a next command. CONSTITUTION:A program supplies a movement signal to the 1st shaft driving amplifier 51 and the 2nd shaft driving amplifier 52 through a control part 1 including a CPU to drive the 1st shaft controlled motor 61 and the 2nd shaft controlled motor 62. The command of the 1st shaft stored in a memory 2 is executed through the operation of the control part 1, the 1st shaft interruption processing part 22 and a numerical arithmetic part 3 to supply a movement signal to the 1st shaft driving amplifier 51, thereby driving the 1st shaft controlled motor 61. When the 2nd shaft interruption input signal 73 is inputted to the 2nd shaft interruption input circuit 13, the 2nd shaft controlled motor 62 is stopped through the operation of the control part 1, the 2nd shaft interruption processing part 23, and numerical arithmetic part 3 and a next command of the 2nd shaft which is stored in the memory 2 is executed to restart the 2nd shaft. Consequently, the respective shafts are brought into independent interruption control of a numerical controller and the inexpensive, high-precision controller is obtained.
