STAC6 microstepping drives

The range of high power/high speed microstepping drives delivers up to 13Nm of holding torque from a 320 VDC bus. The increased bus voltageon the STAC6 effectively extends the power range of stepper drive technology and includes additional features that together derive improved performance from today's stepper motors. The packaged drives are aimed at applications where the simplicity and comparatively lower cost of stepper motor control can replace servomotor positioning. Available in choice of S, Si and Q control versions covering simple step and direction, GUI based programming and host control with optional encoder following for multi-axis motion, the fully protected STAC6 series drive stage features advanced 20KHz PWM current control with anti-resonance, torque ripple smoothing and waveform damping control algorithms - with programmable microstepping emulation to 50,800 steps/rev for smooth dynamic performance.
