Npaq 6U Drive Rack
PITTSBURGH, Dec. 18, 2013 — Aerotech Inc.’s Npaq 6U high-power drive rack provides up to 30 A for brush, brushless or stepper motors, and its plug-in amplifiers support both linear and pulse-width-modulation (PWM) topologies.
Featuring high-performance, double-precision digital signal processors (DSPs), the system performs current- and servo-loop closures digitally, enabling loop-closure rates up to 20 kHz. It handles digital and analog I/O processing, data collection, laser firing and encoder multiplication tasks in real time.
Standard options include integrated encoder multiplication, per-axis brake control logic, I/O expansion and integrated emergency stop circuitry. The device contains two configurable power supply sections rated at 600 W each to support a variety of motors with different operating voltages.
A dedicated Ethernet port communicates with third-party I/O modules for increased I/O count applications.
