摘要： A machine position detecting apparatus according to the invention detects the absolute position of a machine by a pulse coder or the like attached to a movable element. Whenever the movable element of the machine is stopped, a check is performed to determine whether the detected position of the movable element is accurate. This is accomplished by a counter for counting the amount of shift of an absolute position detector circuit in one revolution based on a rotational position signal, and a collator for collating contents of the counting means with contents of position memory means and checking the stored contents of the position memory means when the movable element is stopped.

摘要： A device for detecting the absolute position of a moving part of a machine using a rotary encoder. The object is to detect any error that may develop in the content stored in the absolute position storage means. A register (4) stores the absolute position of when the power source circuit is closed and the present absolute position that is detected by a rotary encoder (2) based on the subsequent amount of movement. A counter (5) counts the quantity of shift from a position of generating a one-turn signal of the rotary encoder (2). When the moving part stops, a coincidence circuit (6) collates the present position stored in the register (4) with the counted content of the register (5), and generates an error signal when they are not in agreement. Therefore, the machine tool and the like are prevented from erroneously operating.
