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.
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
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.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
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.
Over-voltage, under-voltage, over-temp, internal motor shorts (phase-to-phase, phase-to-ground)
Automatic idle current reduction to reduce heat after motor stops moving, software selectable current and idle delay
Software selectable from 200 to 51200 steps/rev in increments of 2 steps/rev
Performs high resolution stepping by synthesizing fine microsteps from coarse steps. Reduces jerk and extraneous system resonances.
Raises the system damping ratio to eliminate midrange instability and allow stable operation throughout the speed range and improves settling time
Torque Ripple Smoothing
Allows for fine adjustment of phase current waveform harmonic content to reduce low-speed torque ripple in the range of 0.25 to 1.5 rps
Optional encoder feedback for stall detection and stall prevention
Configurations are saved in FLASH memory on-board the DSP
