Abstract:
According to an aspect of the invention, a motor stop control method of a motor stop control apparatus which includes an arithmetic control unit and a detection unit. The arithmetic control unit has a stop start position at which a stop control is started from a position which is a predetermined angle before a target position at which a motor stops. The arithmetic control unit calculates a rotational speed of the motor at the stop start position on the basis of a detection value of the detection unit, and a stop time at which the rotational speed of the motor reaches zero from the stop start position on the basis of a deceleration line indicating a change in the rotational speed of the motor, the rotational speed of the motor, and the predetermined angle.

Claim (Index 1):
A motor stop control method of a motor stop control apparatus including an arithmetic control unit configured to control a motor and a detection unit capable of detecting a rotational state of the motor, the arithmetic control unit having a stop start position at which a stop control is started from a position which is a predetermined angle before a target position at which the motor stops, the motor stop control method comprising:\n a rotational speed calculation step in which a rotational speed of the motor at the stop start position is calculated from a detection value detected by the detection unit; a stop time calculation step in which the arithmetic control unit calculates a stop time until the rotational speed of the motor reaches zero from the stop start position, on the basis of a deceleration line indicating a change in the rotational speed of the motor, the rotational speed, and the predetermined angle; a rotational speed target value calculation step in which the arithmetic control unit calculates a rotational speed target value of the motor every time the control cycle elapses, from a control cycle controlling the motor and the stop time; a deceleration section calculation step in which the arithmetic control unit calculates a deceleration section of the motor, by multiplying the calculated rotational speed target value by the control cycle; a temporary target position calculation step in which the arithmetic control unit calculates a temporary target position, from a sum of the deceleration section and the stop start position; a drive command calculation step in which the arithmetic control unit calculates a drive command on the basis of a difference between a current position of the motor and the control target value, after determining the current position of the motor from the detection value detected by the detection unit using the temporary target position as a control target value; and an instruction step in which the arithmetic control unit outputs the drive command to the motor.
