Measuring only 1.65" x 1.65" X 0.4" (42mm x 42mm X 10mm), the fully intelligent stepper motor Controller + Drivers runs 4 fully independent stepper motors (see wiring diagram). Operating from a 8V to 30V supply the controller regulates to any motor voltage via software command. (Eg 3V motor can be run with 24V supply). Commands can be issued from any serial terminal program (such as HyperTerminal) or from the EZStepper Windows application.

The EZ4AXIS17XR-ST will drive 4 motors at 0.25 Amp with a setting of move current m=50. However with careful selection of motors and/or improved cooling and/or low move time duty cycle it is possible to run motors at 0.5 Amps at m=100. See Command Set for details.

The Commands are intuitive and simple. For example, the command A10000 will move the stepper motor to Absolute position 10000. (This communications protocol is compatible with devices that use the Cavro DT or OEM protocol.)

The EZStepper is also capable of stand-alone operation with no connection to a PC. It can be set to execute a preset string of commands upon power up (i.e., only power is required in this mode). The Commands include nested loops and execution halt pending a switch closure, which is useful in stand-alone applications.

The EZ4AXIS17XR-ST Stepper Motor Controller will typically work with any stepper motor that is 3" or smaller (size23 or smaller). Our Starter Kits enable a first time user to make a Stepper Motor move intelligently in less than half an hour.
