The Using of L297 in Stepper Motor Driving Applications
The Using of L297 in Stepper Motor Driving Applications - Here we provide you with an application note article contain information about the L297 Stepper Motor Controller L297 and L298N driving
You will be taken into sections discuss the advantages of L297 + driver combination, the used with an L298N or L293E bridge driver, stepper motor basic types (unipolar, bipolar and variable reluctance),
bipolar permanent magnet stepper motor, drive sequences for a two phase bipolar stepper motor, generating suitable phase sequences for half step, one-phase-on full step and two-phase-on full step operation.
Also, there are circuit diagrams such as the L297 contains translator (phase sequence generator), a dual PWM chopper and output control logic, the L298N connected to the first phase of a two-phase bipolar motor,
the L297A with a clock pulse doubler compared with L297, L297 and L298 driving a bipolar stepper motor with up to 2A phase currents (click image to enlarge), and pin function – pin connection for L297 and L297A.
