PURPOSE:To perform the operation adjustment of an element to be controlled observing the display means of an NC device itself, by displaying the desired operation command signal of the element to be controlled or the actual waveform of an operation signal by the display means. CONSTITUTION:A speed command digital signal from a deviation counter 47 is inputted to a servo waveform input interface 61. A pulse signal from an encoder 51 is also inputted to the interface 61. Furthermore, to the interface 61, the detecting signal of a limit switch 63 which detects the fact that a stroker reaches to a bottom dead center is also supplied. The input signal of the interface 61 is stored in a graphic RAM31. When a CPU39 calls a text RAM 35 and supplies a waveform display signal to a CRT controller 33, the controller 33 calls a stored digital waveform signal from the RAM31, and displays it on a CRT19. Therefore, it is possible to confirm the adjustment of the NC device observing the display on the CRT19.
