Atlas Developer’s Kit

Atlas® Digital Amplifier Complete Technical Reference
A
• L-bracket base and, if vertical Atlas units are installed, vertical plate for heat sink attachment with
associated mounting hardware (comes in 1 or 4 axis version)
The base plate provides a stable mechanical base from which you can connect and operate your prototype system.
With the vertical plate installed the Atlas units have additional heat sinking, which can be extended further by
connecting the vertical plate to your own heat sink or cold plate.
A.2
Installation and Getting Started
In these instructions it is assumed that you have purchased one of the various Magellan Developer’s Kits, which come
with the Pro-Motion exerciser and tuning software. If you have not purchased a Magellan DK then you will still find
these instructions useful, however you will use the detailed connections detailed in
Section A.3, “Atlas Carrier Card
to connect your system and begin operation.
A.2.1
SPI Bus Connection
You should plug in the provided 12" DB9 cable at the DB9 connection of the carrier card. Once you have plugged in
the DB9 cable, you can skip forward to
Section A.2.2, “Motor Connections,”
and continue from there.
Figure A-2:
Connecting
DB9 Cable to
Carrier Card
The DB9 connections used with the Atlas DK are not compatible with standard RS232 serial ports. Do not at-
tempt to plug this connector directly into your PC.
The SPI bus is not designed to operate external modules by cable connection, and therefore in production appli-
cations it is recommended that Atlas units be located on the same printed circuit card. Regardless of where Atlas
is located, it is the responsibility of the user to ensure that SPI signals are noise free and within Atlas unit’s timing
specifications.
