The STM-R is an integrated Drive+Motor, fusing step motor and drive technologies into a single device, offering savings on space, wiring and cost over conventional motor and drive solutions. STM-R offers NEMA 17, and 23 two frame sizes
Anti-ResonanceStep motor systems have a natural tendency to resonate at certain speeds.The SR drives auaomatically 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 EmulationWith 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 SmoothingAll 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 SmoothingCommand 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
Improves smoother system performanceAt start-up the drive measures motor parameters, including the resistance and inductance, then uses this information to optimize the system performance.
Over-voltage, under-voltage, over-temp, internal motor shorts (phase-to-phase, phase-to-ground)

Step Input STEP+/-
Inputs: optically isolated, 5 - 24 volts, min. pulse width 250 ns., max. pulse frequency 2 MHz; motor executes one step on the falling edge of the STEP input signal
Direction Input DIR+/-
Inputs: optically isolated, 5 - 24 volts, min. pulse width 50 μs, max. pulse frequency 2 MHz; direction of rotation is controlled by the DIR input state
Enable Input EN+/-
Inputs: optically isolated, 5 - 24 volts, min. pulse width 100 us., max. pulse frequency 10 KHz; enables or disables the drive amplifier
Open Collector, 30 volts, 100 mA max, max. pulse frequency 10 KHz; closes when the drive encounters an error, open when the drive is operating normally
Running current - output current is set by SW1 & SW2 with a total of 4 settings: 50%, 70%, 90% and 100% of the running current.
Idle Current - can be set by SW3 for 50% of running value to reduce motor and drive heating, or for 90% when a high holding torque is required.
Self test - set by SW4 to check the physical operation of the motor.
Input Noise Filter - set by SW5 this filters out unwanted electrical noise. The frequency of the filter can be set to 150KHz or 2MHz.
Step Smoothing Filter - also called microstep emulation, smooth motion can be obtained from coarse command signals by setting SW6 to ON.
Anti-Resonance/Electronic Damping - setting SW7 for the proper inertia load, low (OFF) or high (ON), can greatly improve the motor’s performance.
Step Pulse Type - SW8 allows the motor to be used with either CW/CCW pulse type command signals (ON), or STEP/DIR pulse type signals (OFF).
Microstep resolution - SW9, SW10, SW11, and SW12 set the microstep resolution at one of 16 settings: 200, 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, or 25000 steps/rev.
