Motor drive control device, motor drive control method, and non-transitory computer-readable medium

A motor drive control method comprising:

• counting number of pulses for driving a motor;
• storing, in a memory, driving information including pulse periods for driving the motor to be accelerated, to be at a constant speed, and to be decelerated;
• calculating a deceleration start position indicating an address at which a pulse period is stored, the pulse period being equal to or larger than a pulse period at a time of forced stopping and closest to the pulse period at the time of forced stopping among the pulse periods included in the driving information;
• calculating number of pulses required for stopping the motor at an exciting position of the motor in stopping the motor;
• and
• controlling drive by outputting a total number of pulses of the counted number of pulses and number of pulses from the deceleration start position until the motor is stopped to stop a deceleration operation in forcibly stopping the motor, and outputting a shortage of the number of pulses required for stopping the motor calculated at the calculating the number of pulses required for stopping the motor.

A non-transitory computer-readable medium comprising computer readable program codes, performed by a processor, the program codes when executed causing the processor to execute:

• counting number of pulses for driving a motor;
• storing, in a memory, driving information including pulse periods for driving the motor to be accelerated, to be at a constant speed, and to be decelerated;
• calculating a deceleration start position indicating an address at which a pulse period is stored, the pulse period being equal to or larger than a pulse period at a time of forced stopping and closest to the pulse period at the time of forced stopping among the pulse periods included in the driving information;
• calculating number of pulses required for stopping the motor at an exciting position of the motor in stopping the motor;
• and
• controlling drive by outputting a total number of pulses of the counted number of pulses and number of pulses from the deceleration start position until the motor is stopped to stop a deceleration operation in forcibly stopping the motor, and outputting a shortage of the number of pulses required for stopping the motor calculated at the calculating the number of pulses required for stopping the motor.
