Real Time StUntil 256 Axes Real Time Stepper Motor Controller


ST600µNet controls "four" stepper motors independently trough a set of triggers mode. Can be connected directly to a host computer via USB HDI link, or in conjunction with rmv_Tasker Module , allowing in this way a full IoT capabilities via Ethernet, or WI-FI. The ST600µNet Series can operate in both monophasic and biphasic mode, with step mode size as follows: full step, half step, quarter step, 1/8 step, 1/16 step, 1/32 step, 1/64 step, 1/128 step, and 1/256 step. The ST600µNet Series motor current depending on the model can drive: A) From 0.5 Amp to 4.5 Amps, and B) From 1 Amp to 8 Amp per axis. Furthermore, this series provides the capability of having a step rate as fast as 22,000 steps/second. Each Motor Manufacturer Parameters can be saved to RMV859 Internal Flash. In Addition, ST600µNet support the following Motion Mode: Trapezoidal, Speed Control, Profile Motion, S-Curve, PI, Current Controlled, Sequential Motion, Closed LOOP, and Voltage Constant. As part our commitment to "Open Source" ST600µNet application software will be supported to: Raspberry PI, Beaglebone, Arduino boards. Free samples can be downloaded via GitHub.
