How to operate the digital amplifier series NPCxxxDIG
8.1 Common Introduction
Our line of digital piezo amplifiers d-Drive from
Newport Corporation
has now been expanded
with the addition of the OEM amplifier series
NPCxxxDIG
including
NPC300DIG
with 300mA
output current. These amplifiers are designed for use as a single unit in industrial settings. It is
compact, robust, and mountable in different manners and is highly reliable. The
NPCxxxDIG
was
designed
for
universal
use
with
a
wide
main
supply
voltage
from
10V to 30V DC. The casing is available in
a screw slot version, or for mounting in a 19” rack
mount casing.
Piezo actuators can be controlled in three different ways, either by using the encoder knob on
the front panel, by analog signal ranging from 0 to +10V, or by PC-Interface RS232. The best
results for resolution and accuracy can only be achieved by setting the digital target values. The
high performance of the
NPCxxxDIG
with 20bit effective resolution guarantees the customer
high speed positioning, with the highest accuracy available. It includes rise time optimization
and an active oscillation damping for every special application.
The
NPCxxxDIG
comes with an auto calibration routine and automatic sensor identification
(ASI). All values of the actuating system, like capacitance, measurement system, resonant
frequency, and motion, are automatically stored in the amplifier. An automatic amplifier
optimization occurs after actuator identification. All this makes our system configuration very
easy and saves our customers a lot of time.
A unique feature of the
NPCxxxDIG
is that it can be used in combination with strain gauge or
capacitive feedback sensors without additional modification. The DSP (digital signal processor)
runs at 64 MHz, and at a sampling rate of only 20 µsec. We have also implemented adjustable
features such as slew rate, notch filter, and pass filters. A built-in function generator offers sine,
triangular, and square functions, as well as noise and sweep.
All operating elements are usable from the front side. The PC-interface on the back side allows
wiring in switch cabinets. Extension cables for great distances are available.
