X-MCA Series
Stepper Motor Controllers
About This Series
The X-MCA is a high resolution, small form factor stepper motor controller for bipolar stepper motors and actuators up to 1.0 Arms (1.4 A peak) per phase. An optional indexed knob provides convenient manual control for versatile operation even without a computer.
This is our most compact stand-alone controller available. It has been designed to fit in tight spaces and provide a range of mounting options including 90 degree stacking and 35 mm DIN rail mounting via optional accessories AB158 and AB159.
An intuitive ASCII interface allows the user to easily communicate with the device through Zaber Launcher (our free software), as well as third-party terminal programs.
When daisy-chained with several units, the X-MCA can share a single power supply with multiple X-Series products.
