High power drive rack
15 January 2014
Aerotech’s Npaq 6U is a high-power drive rack that uses plug-in amplifiers supporting both linear and PWM topologies to control brushless, DC brush or stepper motors.
PWM amps offer up to 320 VDC operating voltage and 30 A peak current capability. Linear amplifiers provide up to 80 V and 20 A peak current for high power, low-noise applications.
Featuring high-performance, double-precision DSPs, the Npaq 6U performs both current loop and servo-loop closures digitally to ensure the highest level of positioning accuracy and rate stability.
