The SMD4 is a single-axis bipolar stepper motor drive that is engineered to drive vacuum-compatible stepper motors with maximum performance and minimal heat. It is optimized for use with AML UHV-compatible motors.
Overview
Optimized for vacuum: Single-channel UHV stepper motor driver, ideally suited for use with our range of UHV stepper motors
USB, Ethernet and RS232/485: Multiple interfaces for easy control from a host PC or PLC
Maximizes motor operating time: Minimize temperature rise and outgassing with advanced drive current profiles
Motor thermal protection: Monitor motor temperature using the thermocouple or RTD inputs. Drive current is removed if temperature exceeds safe levels
Voltage boost feature: Power using a standard 48 Vdc power supply, and the drive voltage is boosted to 67 Vdc to maximize speed and torque
Smooth motor operation: Up to 256x micro-step resolution minimizes resonances, providing smooth motion
Performance: Current adjustable from 0 A to 1 A RMS in 30 mA steps, with dynamic set-points for acceleration, running and hold currents
