Introduction Ensemble Epaq Hardware Manual
Chapter 1: Introduction
Aerotech’s Epaq is a 3U height, 19” wide, rack-mountable, intelligent drive chassis, capable of powering up
to nine axes of motion. Six axes of motion control are available in one integrated, stand-alone package and
can be expanded to nine axes of motion control externally. This flexible configuration style allows users to
mix and match drive types (linear versus PWM, brush or brushless, stepper, etc.) within the same
positioning system using a common programming and control platform. Multiple Epaqs can be controlled
from one Windows PC through Ethernet or USB. Optional on-board encoder interpolation offers the user
programmable axis resolution (assuming a sine-wave encoder input signal), including the ability to change
interpolation (multiplication) values through software.
