<p>An electronic multi-shaft absolute position detecting device, 1 comprising an absolute position recording circuit 11, an interface circuit 12, a spare power circuit 13, and a cooperating application software circuit, detects incremental position signals produced by a measuring system 3 associated with a numerically controlled machine tool and converts the signals into absolute position signals to thereby record machine-part position values. In case of a power cut, the spare power circuit 13 can provide the absolute position recording circuit 11 and interface circuit 12 with power so that the absolute position recording circuit 11 can continuously detect the position signals produced by the measuring system 3 and record the position values thereof. After the power supply is restored, the absolute position recording circuit 11 can respond to the requirement of a numerical control system 2 to read the final position values of the machine when the power is restored and transmit the final position values to the numerical control system 2 through the interface circuit 12, making the machine tool automatically restore to continue the original processing operation. <IMAGE></p> |
