Claims

[Scope of utility model registration request]

In a numerical control device equipped with an absolute position detector that detects the position of a controlled moving object using a battery as a power source even when the control power is cut off, the system positions the controlled moving object at a mechanical reference point and calculates the coordinate values of that point. By presetting, a start signal is obtained that instructs the axis on which the origin initial setting operation for setting the origin of the control coordinate system is to be performed, and the direction viewed from the current position as viewed from the mechanical reference point, and is sent to the movement command control unit. The sensor automatically performs the movement operation necessary for setting the origin, and when the detector reference point is not passed, the redo operation is automatically performed, and the sign of the preset coordinates can be automatically determined. Absolute position detection numerical control device.
