Introduction
The SMD4 stepper motor drive is a single-axis bipolar stepper motor drive, intended for use with AMLs range of vacuum-compatible stepper motors (VCSMs). It maximises motor performance while minimising temperature rise.
Powerful software is supplied with the SMD4 that enables you to easily control and configure multiple SMD4 units
simultaneously, in a single, user-friendly graphical interface. For advanced users, the drive can also be controlled via scripting in JavaScript.
The drive features extensive communications options, including USB, RS232, RS485 and Ethernet. It also includes an innovative boost feature; this uses an internal circuit to increase the 48 V input up to 67 V for driving the motors. This allows the use of standard 48 V power supplies without compromising on motor performance.
The drive supports incremental and absolute BiSS encoders (when so equipped). This enables features including closed loop control and virtual limits based on encoder position and greatly expands the features of the product.
