Abstract
A controller outputs a first detection signal indicative of the position of a control shaft, and by forwardly converting a motor position signal indicative of the position of a motor through use of a motion conversion characteristic of a power transmission unit, outputs a second detection signal corresponding to the position of the control shaft. Then using the respectively output first detection signal and second detection signal, the controller doubly determines whether or not the state of the control shaft is abnormal.
