Abstract
A stepping motor controller for controlling a stepping motor which drives a load, including: a load drive state detection section which detects a driving state of the load; and a control section which controls the stepping motor, when a detection result of the load drive state detection section is beyond a prescribed range, so as to maintain a driving speed of the load, and when the detection result of the load drive state detection section is within the prescribed range, so as to control the driving state of the load based on a control pattern.
Claims18
A stepping motor controller for controlling a stepping motor which drives a load, comprising:
- a load drive state detection section structured to detect a driving state of the load driven by the stepping motor;
- and
- a control section structured to monitor whether a speed fluctuation of the load detected by the load drive state detection section is within a prescribed range or beyond the prescribed range, wherein the prescribed range is predetermined such that the stepping motor is not put into the step-out state and the driving state can be controlled stably when the speed fluctuation of the load is within the prescribed range, and control the stepping motor, when a detection result of the load drive state detection section is beyond a prescribed range, so as to maintain a driving speed of the load, and when the detection result of the load drive state detection section is within the prescribed range, so as to control the driving state of the load based on a control pattern.
A stepping motor control method for controlling a stepping motor which drives a load, comprising:
- detecting a driving state of the load driven by the stepping motor;
- monitoring whether a speed fluctuation of the load is within a prescribed range or beyond the prescribed range, wherein the prescribed range is predetermined such that the stepping motor is not put into the step-out state and the driving state can be controlled stably when the speed fluctuation of the load is within the prescribed range;
- and
- controlling the stepping motor, when a detection result of the driving state of the load is beyond a prescribed range, so as to maintain a driving speed of the load, and when the detection result of the driving state of the load is within the prescribed range, so as to control the driving state of the load based on a control pattern.
A computer readable medium stored thereon a program for causing a computer to execute the steps of:
- detecting a driving state of the load driven by the stepping motor;
- monitoring whether a speed fluctuation of the load is within a prescribed range or beyond the prescribed range, wherein the prescribed range is predetermined such that the stepping motor is not put into the step-out state and the driving state can be controlled stably when the speed fluctuation of the load is within the prescribed range;
- and
- controlling the stepping motor, when a detection result of the driving state of the load is beyond a prescribed range, so as to maintain a driving speed of the load, and when the detection result of the driving state of the load is within the prescribed range, so as to control the driving state of the load based on a control pattern.
