Off-the-shelf dual axis motion control

The dual-axis EZHR17EN Stepper Motor Controller +Driver is designed for rapid off-the-shelf implementation in miniature applications.

Built by AllMotion, the dual-axis capable EZHR17EN high-resolution intelligent stepper motor controller + driver with encoder feedback measures 1.6-in ×1.6-in (40mm × 40mm). It provides up to 2 amps drive current for one axis and up to 1 amp for the second with optional second stepper or bidirectional DC driver daughtercard. The EZHR17EN and daughtercard can microstep up to 1/256 and 1/16 steps, respectively.

"AllMotion's EZHR17EN's dual axis positioning capability provides high-resolution coordinated motions for applications such as an X-Y robot or a syringe and valve drive with unparalleled ease," says David Goodin, president of AllMotion. "Engineered for rapid implementation as an off-the-shelf component, the EZHR17EN makes dual axis motion for miniature products low cost and easy."

The EZHR17EN gives precise positioning, acceleration, and velocity capability to any stepper motor that is 3-in. or smaller (NEMA size 23 or smaller). The controller is easily integrated into OEM instrumentation across a wide range of industries.

Capable of high-speed and highly complex motion - up to 20 million microsteps per sec., the EZHR17EN follows simple and intuitive command sets compatible with devices using the Cavro DT or OEM protocol. Commands can be issued from any serial terminal program like HyperTerminal or from the EZ Stepper Windows application. In addition, the control is capable of standalone operation with no connections to a PC. It can be programmed to execute a preset string of commands upon power-up. These strings and other programs are stored in onboard EEPROM.

The fully intelligent stepper motor controller + driver is designed to fasten to the back of the stepper motor. A single four-wire bus equipped with two power wires and two communication wires can link up to 16 stepper motor controllers in a daisy chain.
