ST600µNET


Description


ST600µNet is our new Stepper Controller Board that provides more freedom then our ST400NT. Independent control on as many Stepper Motors as needed with additional ST600NET and rmv-µTOS. The ST600µNet  Series can operate in both monophasic and biphasic mode, with step mode options as follows: full step size,half step size, quarter step size, 1/8 step size, 1/16 step size, 1/32 step size, and 1/64 step size. The boards also support acceleration and deceleration capabilities. The ST600 Series provides from half Amps to 4 Amps per motor. Furthermore, this series provides the capability of having a step rate as fast as 25,000 steps / second. Speed, position, acceleration / diacceleration, trapazoidal, profiling, and parabolic control are all supported by this series.
