Zusammenfassung: | A control device 10 for a rotary apparatus 1 includes a driving circuit 40 configured to apply a driving voltage to a stepping motor 20 that rotates an output gear 74, and a control circuit 30 configured to output, to the driving circuit 40, driving pulses in a number corresponding to a driving target included in a driving command signal from the outside. The control circuit 30 includes a driving-pulse output unit 61 configured to output the driving pulse in the number corresponding to the driving target, a position-information acquiring unit 52 configured to acquire position information from a potentiometer 75 that reads a rotating position of the output gear 74 of the rotary apparatus 1, and a rotation-abnormality determining unit 59 configured to determine, based on the position information acquired by the position-information acquiring unit 52, whether a rotation abnormality has occurred in the rotary apparatus 1. |
