The SMD3 is a single-axis bipolar stepper motor drive that is engineered to operate vacuum-compatible stepper motors with maximum performance while minimising temperature rise. It is optimised for use with AML UHV-compatible motors.
Powerful software is supplied with the SMD3 that enables you to control and configure multiple SMD3 units simultaneously, in a single user-friendly graphical interface.
Overview
Single-channel UHV stepper motor drive optimised for vacuum use, ideally suited for use with our range of UHV stepper motors
Advanced low-power drive techniques for minimum motor temperature rise, minimum outgassing and maximum operating time
Holding torque can be controlled independently of dynamic torque under program control, to reduce power
Full-step and up to 256x micro-step resolution, with user-configurable transition from micro step to full-step mode (stops on full-step positions only; micro-stepping used for control of resonance and smoother step transition)
Continuous monitoring of motor temperature with automatic shutdown if motor temperature exceeds tolerable levels
Current adjustable from 0 A to 1 A RMS in approx. 30 mA steps
2 x configurable limit inputs
Opto-coupled step, direction and enable interface
Control via USB
Comprehensive configuration and control software supplied, or interface to your own application. C# API is available
