■ Description

The ST series are compact digital stepper drives with multiple control options and many sophisticated features. Step motors run smoother and faster than ever with features of advanced current control. With mutiple control options, ST series support stand-alone control mode Q programming and various industry field bus controls as RS-232/485, Ethernet UDP/TCP, CANopen and Ethernet/IP. The ST series also has optional encoder feedback with close loop for improved system performance and reliability.

■ Features

Anti-Resonance
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
Microstep Emulation
 
Torque Ripple Smoothing
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. Produces smoother motion at low speeds
 
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
Command Signal Smoothing
 
Auto Setup & Self Test
At 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.
