Japanese Patent JP2664331
Kind Code:
B2
Abstract:
PURPOSE: To provide an inexpensive motor controller which can synchronously operate multiple controllers.
CONSTITUTION: A motor controller 13 is the controller which controls the rotating speed of the rotating shaft of a direct drive motor 14 in accordance with angle detecting resolvers 11 and 12 which are directly fitted to the rotating shaft and detect the rotational angle of the rotating shaft and is provided with an R/D converter 16 which converts the angle outputs of the resolvers 11 and 12 into digital values and an angle calculating program 27 which is used for calculating the absolute angle of the rotating shaft based on the output of the converter 16. The controller 13 is also provided with a position output circuit 24 which transmits 8-bit digital data calculated in accordance with the program 2 to an external device.
