Electronic multi-shaft absolute position detecting device

摘要

An electronic multi-shaft absolute position detecting device comprising an absolute position recording circuit, an interface circuit, a spare power circuit, and a cooperating application software circuit is used to detect the increment position signal produced by the measuring system of the numerical control machine tone and convert the signal into absolute position signal and record the machine position value. In case power is cut off, the spare power circuit can provide the absolute position recording circuit and interface circuit with power so that the absolute position recording circuit can continuously detect the position signals produced by the measuring system and record the machine position value thereof. After the power supply is restored, the absolute position recording circuit can respond to the requirement of a numerical control system to read the final position value of the machine when the power is restored and transmit the final position value to the numerical control system through the interface circuit, making the machine tool automatically continue the original processing operation.
