Abstract
A control system for monitoring a control state of a target device that receives drive control by a motor includes a setting unit that sets an origin for position monitoring of the target device and a sensor that detects the target device reaching a predetermined position. The setting unit includes an obtainer that obtains, under predetermined drive control over the target device by the motor, leading and trailing edges in a detection signal from the sensor in response to the target device reaching the predetermined position, and a calculator that calculates the origin using first position information associated with a target device position and calculated based on the leading and trailing edges in the detection signal and second position information associated with the target device position and different from the first position information.
