Classification: CPC B  H | IPC B  H

Claim 0:
1. A control system, comprising:
a motor;
a carriage configured to be driven by the motor to reciprocate;
a processing head mounted on the carriage and configured to eject liquid droplets to a target object when the carriage moves along a moving passage of the carriage; and
a controller configured to control the motor using a selected one of a plurality of control modes, each control mode having a different speed profile, each speed profile defining movements between a time when the carriage starts moving to a time when the carriage stops at a turnaround point of reciprocating movement of the carriage,
wherein the controller is configured to perform:
obtaining temperature information related to a temperature of the motor;
selecting a candidate control mode;
predicting, for the candidate control mode, prior to driving the motor based on the candidate control mode, a maximum temperature of the motor in a case where the motor is driven by the controller using the candidate control mode and data for a work unit, for the entire work unit until processing of the work unit is completed;
determining whether the predicted maximum temperature is less than a reference temperature;
selecting the candidate control mode, as a target control mode when it is determined that the maximum temperature for the candidate control mode is less than the reference temperature; and
causing the carriage to reciprocate by controlling the motor in accordance with the target control mode.
