The invention relates to a method for fault monitoring, a device, a control unit and a system thereof. The system comprises the components of at least one current senor which is used for continuouslysensing current magnitude of a motor for outputting rotation movement in a movable system and outputting a sensing signal that indicates the sensed current magnitude, wherein the mobile system at least comprises a motion converting component which is used for converting rotation motion to linear motion and a workpiece that is driven by linear movement; at least one vibration sensor which is used for continuously sensing vibration magnitude of the motion converting component and outputting the sensing signal that indicates the sensed vibration magnitude; and a control unit which is used for determining whether a fault of the movable system occurs based on the received sensing signal of at least one current sensor and at least one vibration sensor. By means of the method, the device, the control unit and the system,
