Press release date: December 5, 2013

High-power 6U modular drive chassis in 19-inch rack-mount design
Drive brush, brushless or stepper motors with the same amplifier
5 A to 30 A peak output current; supports PWM or linear amplifiers
Digital current, velocity and position loops for improved motion stability
Integrated encoder multiplier for higher throughput and reduced wiring
Encoder and resolver feedback
CE approval

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

Standard options for the Npaq 6U include integrated encoder multiplication, per-axis brake control logic, I/O expansion and integrated emergency stop circuitry.

The Npaq 6U contains two configurable power supply sections rated at 600 W 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.

The Npaq 6U has a dedicated Ethernet port to communicate with third-party I/O modules for increased I/O count applications. It supports up to three axes of Position Synchronized Output (PSO) for precise synchronizing of external devices, over-voltage shunt controller and external fans for high-power operation.

For further information, please contact Steve McLane at 412-967-6854 (direct), or via e-mail at smclane@aerotech.com. In addition, more information on the Npaq 6U is available at:
