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 6):
A motor stop control apparatus comprising:\n an arithmetic control unit configured to control a motor; and a detection unit capable of detecting a rotational state of the motor, wherein 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 the motor stops; and the motor stop control apparatus further comprising: a rotational speed calculation unit configured to calculate a rotational speed of the motor at the stop start position from a detection value detected by the detection unit; a stop time calculation unit configured to calculate a stop time until the rotational speed of the motor reaches zero from the stop start position on the basis of the rotational speed and the predetermined angle; a rotational speed target value calculation unit configured to calculate a rotational speed target value of the motor every time the control cycle elapses, from the rotational speed, the stop time, and a control cycle controlling the motor; a deceleration section calculation unit configured to calculate a deceleration section of the motor by multiplying the calculated rotational speed target value by the control cycle; a temporary target position calculation unit configured to calculate a temporary target position from a sum of the deceleration section and the stop start position; a drive command calculation unit configured to determine a 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 calculate a drive command using a difference between the current position of the motor and the control target value; and an instruction unit configured to output the drive command to the motor.
