The Npaq® is the high performance rack-mountable servo amplifier solution for the Automation 3200 motion system. The Npaq® can control up to six axes of motion using a variety of plug-in amplifiers. With both linear and PWM amplifiers capable of driving brushless and DC brush-type servomotors, as well as stepping motors, the Npaq® performs both current loop and servo-loop closure to assure the highest level of positioning accuracy and rate stability.

The Npaq® is built on a high-performance DSP that allows it to perform complex calculations in real time. 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, laser firing, and encoder multiplication.

Two independent supplies provide bus voltage to the amplifiers and may be configured to allow different bus voltages for different motors operating from the same Npaq®.

In order to provide the capability for increased I/O counts for PLC-type applications, the Npaq® has an optional dedicated Ethernet port to communicate with I/O modules from third-party vendors.

Standard options for the Npaq® include on-board encoder multiplication (up to x16384), three-axis position synchronized output (PSO), brake control logic, shunt regulator, external fan tray, and emergency stop relays.
