<p>The present invention provides a washer and washing cycle control method thereof, by which a laundry amount of a laundry can be measured prior to a water supply despite a dry state of the laundry and by which the waste of power consumption and unnecessary use of water can be prevented. The present invention includes a drum holding a laundry therein, a motor rotating the drum, and a control unit executing a sub-routine for measuring a laundry amount of the laundry prior to a water supply to the drum. The sub-routine includes the steps of applying a ramp drive voltage to the motor during an acceleration section to measure a motor RPM amount and a drive voltage amount during the acceleration section, stopping supplying the ramp drive voltage to the motor to measure a motor RPM amount of a deceleration section, and measuring a laundry amount of the laundry using the motor RPM amount of acceleration section, the drive voltage amount of the acceleration section, and the motor RPM amount of the deceleration section</p> |
