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.
