Step & Direction ▪▪ Step & direction ▪▪ CW & CCW pulse Best value for step & direction applications Anti-Resonance/Electronic Damping Run/Stop (Toggle Switch) Step motor systems have a natural tendency to resonate at certain speeds. The STR drives automatically calculate the system’s natural frequency and apply damping to the control algorithm. This greatly improves midrange stability, allows for higher speeds, greater torque utilization, and improves settling times. Speed (Potentiometer) Delivers better motor performance and higher speeds Microstep Emulation With Microstep Emulation, low...
