1. Introduction
ACE-SDC-V3 is a single board cost-effective stepper driver and controller with
USB 2.0 communication.
1.1 Features
-USB 2.0 Communication
-12-24VDC voltage input
-Different configurable current settings from 0 mA to 2.0A peak current
(100 mA resolution)
-Selectable Full, 1/2, 1/4, 16 microstep
-6 Opto-isolated Digital inputs
-2 Opto-isolated Digital outputs
-1 Analog input
-Three different control modes:
•DIO Control – motion is done using the digital inputs and
outputs.
•USB Control – motion is done from PC using USB
communication.
•Analog Control – speed control is done from analog input.
