Abstract: A controlling system includes: a motor; a movable body which is moved by the motor along a movement direction and executes an operation for processing a target; a single detecting unit which is mounted on the movable body and detects first and second detection objects during a movement of the movable body; a rotation amount information outputting section which outputs rotation amount information indicating a rotation amount of the motor; and a controller. The controller executes: a moving process for moving the movable body by the motor along the movement direction; a rotation amount information obtaining process for obtaining first rotation amount information and second rotation amount information; a correction value calculating process for calculating a correction value indicating an actual moving distance of the movable body per predetermined rotation amount of the motor; and a moving distance calculating process for calculating a moving distance of the movable body.

Abstract: An electronic device includes a motor, a moving body on which a processing part is mounted, a rotary encoder, a memory; and a controller. The controller is configured to execute a detection process of detecting a position of the moving body based on an encoder signal, a control process including a first control of controlling movement of the moving body by controlling the motor and a second control of controlling a processing operation by the processing part in a constant speed movement section of the moving body, a determination process of determining a detection error of the position of the moving body generated in an acceleration section of the moving body based on information stored in the memory, and a correction process of correcting at least one of the first control and the second control.

Abstract: There is provided a pulse generator generating a timing pulse based on a detection signal obtained from a detection signal outputting part configured to output the detection signal every time a motor rotates by a predetermined amount which has been previously set. The pulse generator includes: a time information calculating part, and a timing determining part. A time difference between a first calculating timing at which first time information is calculated and a second calculating timing at which second time information is calculated is longer than a time required for the motor to rotate by not less than an angle corresponding to a cogging distance.

Abstract: In a control system, a controller is configured to determine presence or absence of an obstructed area within the intermediate section, and control movement of the moving body in accordance with a selected one of controlling methods including a first and a second control methods. The first control method causes the moving body to move at a first constant speed in the processing section defined within the intermediate section and at a second constant speed faster than the first constant speed in at least a part of a non-processing section within the intermediate section and other than the processing section, the first control method being selected when the obstructed area is absent. The second control method causes the moving body to move at the first constant speed in the processing section and the non-processing section, the second control method being selected when the obstructed area is present.

Abstract: The controller moves a movable body along a moving direction. A recording head and a detector are mounted on the movable body. The detector detects a detection target fixed to an ink receiving unit. The ink receiving unit receives an ink jetted from the recording head at a time of a flushing. The controller obtains, based on a signal from an encoder, a position of the movable body in a case that the detection target is detected by the detector during movement of the movable body. The controller determines a start timing of the flushing based on the obtained position of the movable body.

Abstract: A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.
