Description

The SR series drives are cost-effective, high performance step drives. The design is based on advanced digital current control technology, and features high torque, low noise, and low vibration. The running current, microstep resolution and other parameters are switch selectable.  

Features

Anti-ResonanceStep motor systems have a natural tendency to resonate at certain speeds.The SR drives automatically calculate the system’s natural frequency and apply damping to the control algorithm. This greatly improves midrange stability, allows higher speeds and greater torque utilization, and also improves settling times.
Provides better motor performance and higher speeds
Microstep EmulationWith Microstep Emulation, low resolution systems can still provide smooth motion. The drive can take low resolution step pulses and create fine resolution motion.
Improves overall system performance
Torque Ripple SmoothingAll step motors have an inherent low speed torque ripple that can affect the motion profile of the motor. By analyzing this torque ripple the system can apply a negative harmonic to counter this effect. This gives the motor much smoother motion at low speed.
Produces smoother motion at low speeds
Microstep EmulationCommand Signal smoothing can soften the effect of immediate changes in velocity and direction, making the motion of the motor less jerky. An added advantage is that it can reduce the wear on mechanical components.
Improves overall system performance
Auto Setup & Self TestAt start-up the drive measures motor parameters, including the resistance and inductance,then uses this information to optimize system performance. The drive can also detect open and short circuits.
