■ Description

The STM is an integrated all-in-one solution, fusing step motor and drive technologies into a single device, offering savings on space, wiring and cost over conventional motor and drive solutions.

■ Features

Anti-Resonance
Step 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 Emulation
With Microstep Emulation, low resolution systems can still provide smooth motion. The drive can take low resolution step pulses and create fine resolution motion. Delivers smoother motion in any application
 
Torque Ripple Smoothing
All 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.
 
Command Signal Smoothing
Command 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 smoother system performance
 
Dynamic Current Control
Allows for three current settings to help the motor run cooler and reduce power consumption.
▪ Running Current - the current the drive will deliver for continuous motion.
▪ Accel Current - the current the drive will deliver when accelerating or decelerating.
▪ Idle Current - reduces current draw when motor is stationary.System runs cooler
 
Self Test & Auto Setup
At start-up the drive measures motor parameters, including the resistance and inductance, then uses this information to optimize the system performance.
