Abstract
A control apparatus controls an operation of a self-propelled mechanism of an endoscope. The control apparatus includes a drive circuit that outputs a motor current, a motor current detection circuit that acquires a value relating to magnitude of the motor current as a detection value, a storage circuit that stores a limit value relating to the detection value, and a control circuit that performs an operation as a first controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds a value relating to the limit value, and performs an operation as a second controller that controls the drive circuit so as to stop the motor when it is determined that the detection value exceeds the value relating to the limit value.
