Title:
ZERO RESETTING METHOD AND APPARATUS FOR DOUBLE-SHAFT SAME-GUIDEWAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/142117
Kind Code:
A1
Abstract:
A zero resetting method for a double-shaft same-guideway device. The method comprises: determining origin positions of a first shaft and a second shaft according to an encoder sector of an electric motor or according to the encoder sector of the electric motor and a position difference between the first shaft and the second shaft; after the first shaft passes through a limiting position away from the second shaft and the second shaft passes through a limiting position away from the first shaft, when the encoder sector of the electric motor is an encoder sector corresponding to the corresponding shaft at the respective origin position for the first time, determining that the first shaft returns to the origin position of the first shaft, and the second shaft returns to the origin position of the second shaft; or after the first shaft passes through the limiting position away from the second shaft, when the encoder sector of the electric motor is the encoder sector corresponding to the origin position of the first shaft for the first time, determining that the first shaft returns to the origin position of the first shaft, and after the second shaft passes through the limiting position away from the first shaft, determining, according to a position difference between the position of the second shaft and the origin position of the first shaft, that the second shaft returns to the origin position of the second shaft. Further provided is a zero resetting apparatus for a double-shaft same-guideway device.
