Motor controller suits miniature
applications
The EZHR17EN gives precise positioning, acceleration and velocity capability to any stepper motor that is NEMA size 23 or smaller.
AllMotion has released the dual-axis EZHR17EN stepper motor controller and driver, designed for rapid, off the shelf implementation in miniature applications The 40 x 40mm system provides up to 2A of drive current for one axis and up to 1A for the second with an optional second stepper or a bidirectional DC driver daughtercard

The award-winning dual axis EZHR17EN stepper motor controller and driver is designed for rapid off-the-shelf implementation in miniature applications.
Small claims for DC servo driver and controller
The EZSV10 DC brush servo driver is billed as the smallest fully programmable DC servo driver and controller on the market.
Servo driver offers easy setup
First-time users can make their EZSV10 DC brush servo driver move intelligently in usually less than half an hour.
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 co-ordinated motions for applications such as an X-Y robot or a syringe and valve drive with unparalleled ease", AllMotion President David Goodin said.
"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 NEMA size 23 or smaller.
First-time users are able to make a stepper motor move as commanded less than 30 minutes after opening the box.
The EZHR17EN is easily integrated into OEM instrumentation across a wide range of industries.
The EZHR17EN is capable of high speed and highly complex motion - up to 20 million microsteps per second - yet 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 (such as HyperTerminal) or from the EZ Stepper Windows application.
The EZHR17EN is capable of stand-alone operation with no connection to a PC.
It can be programmed to execute a preset string of commands on power up.
These strings and other programs are stored in onboard EEPROM.
Commands include nested loops and execution halt pending a switch closure, which is useful in stand-alone applications.
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.
