AllMotion: Stepper Motor Driver Controller EZ17

Legacy

The EZStepper was designed to allow the rapid implementation of stepper motor solutions in products requiring automation.

Measuring only 1.6" x 1.6", (10.64mm x 10.64mm), the fully intelligent stepper motor Controller + Drivers is smaller than a standard quadrature encoder. A single 4 wire bus, containing 2 power wires and two communications wires, links up to 16 such stepper motor controllers in a daisy chain (see wiring diagram). Commands can be issued from any serial terminal program (such as HyperTerminal) or from the EZStepper Windows application.

The Commands are intuitive and simple. For example, the command A10000 will move the servo 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 EZ17 Stepper Motor Controller will work with any stepper motor that is 3" or smaller (size 23 or smaller). Our Starter Kits enable a first-time user to make a Stepper Motor move intelligently in less than half an hour.

For new designs, use EZHR17EN.
