Numerical controller with program check function by override switch

A numerical controller which runs a machine according to a program, the numerical controller comprising:

• a processor configured to:
• accept an operation for an override value input by an operator via an override switch;
• control a sending speed of the machine based on the operation;
• detect the operation for the override value and output a notification based on the detected operation;
• control suspension and resumption of a run of the machining program based on the notification output;
• output a notification of an end-point stop request when a first operation pattern for increasing the override value immediately after temporarily reducing the override value to 0% is input by the operator via the override switch during the run prior to an end of the machining program;
• in response to receiving the notification of an end-point stop request,
• suspend the run at the end point of a currently running block of the machining program, and when a second operation pattern for changing the override value is input by the operator via the override switch while the run is suspended, restart the run at the start point of a subsequent block of the machining program after the currently running block without requiring use of a restart switch;
• and
• in response to not receiving the notification of an end-point stop request, automatically continue the run to a plurality of subsequent blocks of the machining program after the currently running block reaches the end point.
