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.

Abstract: A liquid discharge apparatus includes a recording head, a platen, a measuring device, and control circuitry. The recording head discharges liquid droplets. The platen holds a recording medium. The measuring device measures a gap between the recording head and a 5 recording surface of the recording medium held by the platen. The control circuitry causes the recording head to discharge liquid droplets in accordance with print data to perform printing on the recording medium held by the platen, the control circuitry configured to set a range of the gap between the recording head and the recording surface of the recording medium, in which printing is allowed for a type of the recording medium, in accordance with 10 data for specifying the type of the recording medium held by the platen and a measured value of the gap measured by the measuring device.
