Design Features

The Npaq® 6U is designed for applications that exceed the power capacity of Aerotech’s 3U Npaq. The Npaq 6U can be configured with higher wattage transformers and a larger capacity linear amplifier that provides a nearly two-fold increase in power over the similarly configured 3U version.

Featuring high-performance, double-precision DSPs, the Npaq family 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 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 family include integrated encoder multiplication, per-axis brake control logic, I/O expansion and integrated emergency stop circuitry. The Npaq uses plug-in amplifiers supporting both linear and PWM topologies to control brushless, DC brush or stepper motors at up to 320 VDC operating voltage and 30 A peak current capability.

The linear amplifier in the NPaq 6U has twice the output power of the 3U version (80 V and 20 A peak versus 40 V and 10 A peak) for high power, low noise applications. The Npaq 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 has a dedicated Ethernet port to communicate with third-party I/O modules for increased I/O count applications. The Npaq 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.
