[0006]

As described above, the numerical control device executes the numerical control information while referring to the parameter based on the parameter number commanded from the numerical control information. That is, when the parameter referred to by the command from the numerical control information is changed, the control of the machine is changed even if the numerical control information is the same. Therefore, for example, when performing parameter change work to prepare for the next work, it is much more difficult to change the parameter referred to by the numerical control information being selected, even if it is executing numerical control. At some times, the machine may behave unpredictably by the operator, which is very dangerous. The present invention has been made under the circumstances as described above, and the present invention notifies a worker of a reference state of a parameter from the numerical control information being executed, and a numerical value capable of preventing a work mistake when changing the parameter. It is to provide a control device.
