Abstract
A numerical control device includes a CPU for outputting a position command value of a servomotor; an IC including a servo controller for outputting a current command value to an amplifier for driving the servomotor, and an I/O unit for inputting and outputting an external signal; a DSP for reading the position command value and performing control so as to move the servomotor to a position indicated by the position command value; and an inter-device communication path between the CPU and the IC. The IC includes an internal bus connected to a communication interface connected to the inter-device communication path, and the I/O unit; and an internal communication path for directly transmitting a signal between the servo controller and the I/O unit without passing through the internal bus.
