Npaq 6U data sheet - .PDF file.

Aerotech has released its Npaq 6U high-power drive rack, which uses plug-in amplifiers supporting both linear and PWM topologies to control brushless, DC brush or stepper motors.

Its PWM amps offer up to 320VDC operating voltage and 30A peak current capability, while linear amplifiers provide up to 80V and 20A 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.

It is this processing capability that allows the Npaq 6U to provide loop-closure rates up to 20kHz and to handle both digital and analogue I/O processing, data collection, laser firing and encoder multiplication tasks in real time.

The Npaq 6U contains two configurable power supply sections rated at 600W each to support a variety of motors with different operating voltages. When only one motor voltage is required, the power supply sections are joined together for even higher power capability.
