ST600µNET  IoT Stepper Motor Controller

Until 256 Axes Trough Deterministic Modbus TCP/IP, IGMP


Description


Each ST600ÁNet controls "Four" stepper motors independently with full chopper driver included, trough a set of different triggers mode. Can be connected “directly” to a host computer via USB HDI to IIC link, “or in conjunction” with rmv_Tasker Module (RTOS with Full Embedded Server), allowing in this way a full IoT capabilities via Ethernet 100T,  WI-FI, or Bluetooth 5.

 The ST600ÁNet 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 ST600ÁNet Series motor current depending on the model can drive: A) From 0.5 Amp to 5.0 Amps, and B) From 1 Amp to 8.5 Amp per axis. Furthermore, this series provides the capability of having a step rate as fast as 25,000 steps/second.

Each Motor Manufacturer Parameters can be saved to RMV859 Internal Flash.

In Addition, ST600ÁNet supports the following Motion Mode: Trapezoidal, Speed Control, Profile Motion,       S-Curve, PI, Current Controlled, Sequential Trigger Motion, Closed LOOP, and Voltage Constant.

As part our commitment to "Open Source" ST600ÁNet application software will be supported to: Raspberry PI, Beaglebone.

Free samples can be downloaded via GitHub. Please see the link bellows.
