4-axis stepper motor controller

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

AllMotion’s EZ4Axis23WV stepper motor controller driver runs four independent stepper motors using intelligent stepper motor controller circuitry. This 4-axis position controller with power drivers features programmable acceleration ramps and speeds using four independent 1 Amp (2 Amp peak) PWM chopper drives.

EZ4Axis23WV, with dual encoders, measures only 2.25″ x 2.25″ x 0.6″ and operates from a 9V to 32V supply and regulates any motor current via software command. Thus, a 3V motor can be run using a 24V supply. This allows engineers to easily design-in the EZ4Axis23WV, regardless of the application’s available power. The stepper motor driver controller operates at up to 59,000 microsteps/second.

Commands can be sent via RS-232, RS-485, USB, or CAN-based communications. The system designer can communicate from their application over a serial port or use the EZCommander Windows application available for download from AllMotion. The device can operate in a stand-alone configuration with no connection to a PC and includes 12 digital I/O and two 1A power on/off drivers. They are daisy-chainable with other AllMotion products using a single 4-wire bus. The EZ4Axis23WV is compliant with RoHS standards for restriction of hazardous substances used in the electronic component.
