Applied Motion Products’ DSP-based stepper drives with encoder options offer a unique feature. The stall prevention feature of the STAC6, ST5, ST10 stepper drives and STM integrated steppers not only prevents stalling, but maintains the position of the motor at rest as well. This feature is called position maintenance. When a motor at rest is forced out of position, position maintenance returns the motor shaft to the original rest position once the unwanted force is removed. This means that no matter what the motor is doing, accelerating or decelerating, moving at a constant speed, or resting at zero speed, the stall prevention and position maintenance features are always working together to keep the motor shaft where it’s supposed to be.
To take advantage of stall prevention and position maintenance in your next stepper system you must first purchase a stepper drive with an encoder feedback connector or an integrated stepper with an integral encoder. For stepper drives with an encoder feedback connector you must also purchase a step motor with an encoder mounted to the rear shaft and a cable to connect the encoder to the drive. All of the stepper drives, integrated steppers, motors, encoders, and necessary cables are available from Applied Motion.
To find stepper drives with encoder feedback connectors, filter on Encoder Feedback=Yes on the Browse Stepper Drives page.
To find integrate steppers with integral encoder feedback, filter on Encoder Feedback=Yes on the Browse Integrated Steppers page.
