STF03 - DC Advanced Microstep Drive w/ Multi Fieldbus options
Applied Motion Products
The STF03 stepper drive is a DC-powered microstepping drive for controlling two-phase, bipolar step motors. It offers advanced current control and an anti-resonance algorithm that electronically damps motor and system resonances to improve motor smoothness and usable torque over a wide speed range. The drive employs electronic torque ripple smoothing and microstep emulation to greatly reduce motor noise and vibration. The drive must be powered from 12 to 48 VDC and can output up to 3.0 A/phase ( Read more...
The STF03 stepper drive is a DC-powered microstepping drive for controlling two-phase, bipolar step motors. It offers advanced current control and an anti-resonance algorithm that electronically damps motor and system resonances to improve motor smoothness and usable torque over a wide speed range. The drive employs electronic torque ripple smoothing and microstep emulation to greatly reduce motor noise and vibration. The drive must be powered from 12 to 48 VDC and can output up to 3.0 A/phase (peak-of-sine) to the step motor. Over-voltage, over-temperature and over-current protection features prevent damage while running in adverse conditions.
