Anti-Resonance/Electronic Damping
Step motor systems have a natural tendency to resonate at
certain speeds. The STM drive+motor automatically calcu-
lates the system’s natural frequency and applies damping
to the control algorithm. This greatly improves midrange
stability, allows for higher speeds, greater torque utilization
and also improves settling times.
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 micro-step motion.
Torque Ripple Smoothing
All step motors have an inherent low speed torque ripple
that can affect the motion of the motor. By analyzing this
torque ripple the system can apply a negative harmonic
to negate this effect, which 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.
Dynamic Current Control
Allows for three current settings to help the motor run cooler and reduce power con-
sumption.

System Runs Cooler
Delivers better motor performance and higher speeds
Delivers smoother motion in any application
Delivers smoother motion at lower speeds
Delivers smoother system performance
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.
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.

Synthesized
Microsteps
The ST drive with the CANopen option board has the ability to access, modify
and trigger a Q program stored in the drive.
The user develops and downloads a program using the Q Programmer™
software via RS-232. The program sequences can then be triggered via the
CANopen network, creating a powerful distributed motion control system.
