1.0 Introduction
Pangolin has been using the ord “Mach” (pronounced mock) as a model designation
for our industrial-grade servo drivers since 1998. Back then, e introduced a unique
servo amplifier having four separate coil drivers for a custom industrial galvanometer,
and dubbed the project “Mach 4”.
Completely setting aside the fact that the ord Mach is a cool ord – one hich
conjures images of the fastest fighter jet airplanes, the ord is actually entirely
applicable to the field of galvanometer scanning. Indeed, ScannerMAX scanners utilize
unusual materials and techniques in their rotor construction, and hile choosing these
materials e often consider the speed of sound through these materials (i.e. the Mach
number). For this reason, e continue to use the ord Mach for our servo drivers.
The Mach-DSP servo driver is Pangolin’s latest and most advanced development in
servo control technology. By taking advantage of high-speed floating-point digital signal
processors, 16-bit data converters, direct digital command input, and highly-
configurable servo algorithms, the Mach-DSP provides full-function, t o-axis servo
driver electronics in a cost-effective and compact package. Many advanced techniques
and user-customizable features are embodied ithin the Mach-DSP hard are and
soft are hich, hen combined ith Pangolin’s ScannerMAX scanners, provide a level
of speed, accuracy and convenience that ere unattainable before no .
The Mach-DSP can be accessed and configured using a PC-based Graphical User
Interface soft are package, here the built-in Test Signal Generator, Oscilloscope and
Dynamic Signal Analyzer can be used to monitor and adjust the more than 50
performance parameters per axis. These performance parameters can be stored in four
separate memory areas (called “tunings”) for instant access and recall at any time.
Additional features and behavioral customizations can be added via firm are updates
that take only a fe minutes to do nload using the PC-based soft are, helping to make
the Mach-DSP a “future-proof” product. Moreover, since the current version of Mach-
DSP firm are uses only a fraction of the on-board memory and only around half of the
CPU band idth, it is possible that customized applications may also be loaded into the
Mach-DSP, helping to reduce the size, po er consumption and cost of an overall laser
system. (Contact us about ho customization could be done for your application.)
The Mach-DSP servo driver as created ith OEMs in mind, incorporating a simple yet
comprehensive and flexible interface structure. This, together ith the modest po er
requirement and compact size allo s laser system manufactures to package the servo
driver electronics, the scanners, and often the po er supply as ell, directly into the
laser projector head.
The purpose of this manual is to familiarize you ith the functionality of the Mach-DSP
servo driver. This manual also provides a brief introduction to the process of servo
tuning, although hen buying a complete system (scanners, mirrors, mount, servo
driver, and cables) the Mach-DSP should arrive already tuned at the Pangolin factory.
We also offer tutorial videos on our ebsite that provide more in-depth information.
