Document Type and Number:

Japanese Patent JP7484538

Kind Code:

B2

Abstract:

To provide a state determination system that determines an on/off state of a switch by satisfactorily detecting an open/closed state of a contact, and to provide a machine tool.SOLUTION: A state determination system 5 includes: a switch 3 having a first contact 31; a first control unit 1 that outputs a first output signal including a first eigenvalue A corresponding to the first contact 31 and has a first output terminal 15 connected to an input side of the first contact 31; and a second control unit 2 that stores a first expected value A corresponding to the first contact 31 and has a first input terminal 26 connected to an output side of the first contact 31 and inputting a first input signal when the first contact 31 is in a closed state. When the first eigenvalue A included in the first input signal matches with the first expected value A, the second control unit 2 determines that the first contact 31 is in the closed state.SELECTED DRAWING: Figure 1
