Abstract
To make it possible to give a drive command and a brake command to a motor using a small number of control signals. For this purpose, a motor control apparatus for controlling a motor via a drive circuit includes a generation unit for generating a short-circuit brake signal for applying a short-circuit brake to the motor in a case where a control signal for controlling the motor instructs a stop of the motor, and an instruction unit for outputting an instruction for the short-circuit brake to the drive circuit in a case where the short-circuit brake signal is being generated, and outputting an instruction based on the control signal to the drive circuit in a case where the short-circuit brake signal is not being generated.
