Motor control device and game machine

A game machine comprising:

• a main game unit;
• a moving body arranged on a front surface of the main game unit and configured to move;
• a motor for driving the moving body;
• a motor control device configured to control the motor;
• and
• a presentation controller configured to control a presentation of an effect in accordance with a state of play;
• wherein
• the presentation controller generates a control command comprising control information that defines an operation of the motor in accordance with the state of play, and transmits the control command to the motor control device;
• the motor control device including comprises:
• a first memory;
• a second memory different from the first memory;
• a communication interface circuit configured to receive the control command;
• a command parser circuit configured to:
• in response to the control command comprising the control information defining the operation of the motor, store the control information in each of the first memory and the second memory;
• generate a first response signal including the control information stored in the first memory when the control command includes a command for verifying a communication state;
• transmit the first response signal to the presentation controller via the communication interface circuit;
• generate a second response signal comprising all or a portion of the control information stored in the second memory in response to the control command comprising a command for verifying a control state of the motor;
• and
• transmit the second response signal to the presentation controller via the communication interface circuit;
• and
• a control circuit comprising a processor configured with instructions to perform operations comprising:
• reading the control information from the second memory;
• and
• determining a setting value for a rotation speed of the motor in accordance with the control information read from the second memory;
• and
• a drive signal generator configured to generate a drive signal that causes the motor to rotate in accordance with the setting value for the rotation speed, and to output the drive signal to the motor.
