Introduction To The MicroLYNX
The MicroLYNX is a powerful
machine control system which
combines a bipolar microstepping
driver with an expandable
programmable controller into a
compact panel mounted assem-
bly.
With the addition of differential
I/O modules, the MicroLYNX
has the capability of driving two
additional axes sequentially or
driving a following axis electroni-
cally geared to the on-board
driver.
The MicroLYNX includes two
independent communication
ports. It will accept commands
from either port and direct output to either as well. A system may be config-
ured to use COMM Port 1 to communicate to a host PC or PLC while using
the COMM Port 2 to communicate with an operator interface or additional
MicroLYNX systems.
The MicroLYNX comes in two output power ranges to fit a variety of
motor sizes. Features such as 5 to 24VDC isolated I/O, multiple communica-
tion types, and numerous expansion options make the MicroLYNX an
effective and powerful machine control solution.
Plug-on accessory modules allow control system designers to tailor the
MicroLYNX System to their needs with minimal cost. The MicroLYNX
may be field upgraded by simply removing the side cover and adding expan-
sion modules.
The MicroLYNX software is upgradeable by using the IMS
LYNX Terminal Software. Updates are posted on the IMS
website and may be downloaded. This allows older units the
ability to use new features and expansion modules as they
become available.
This Quick Guide is a step-by-step usage guide for the MicroLYNX.
While not intended to replace the product manual provided on CD, it
is essential in acquiring a thorough understanding of the MicroLYNX
System. This “Quick Guide” provides the user with detailed connec-
tion and usage examples for the MicroLYNX and its associated expansion
modules, as well as the most commonly used components of the LYNX
instruction set. It also includes an introduction to LYNX programming.
Hi! I’m Motorhead!
I’ll be your guide
through the process
of setting up and
using your MicroLYNX
System!

Mounting Information
The MicroLYNX System may be
mounted to a panel by using standard
#6 (M3) hardware. No heatsinking is
necessary as the system has a built-in
cooling fan. When mounting the
MicroLYNX in an enclosure, ensure
that adequate space is available for air
flow on the fan side of the
MicroLYNX case. Mounting screws
should be tightened to 5 to 7 lb-in
(0.60 to 0.80 N-m) torque.

MicroLYNX Terminology Explained
Throughout this book several terms will be introduced that apply to the
MicroLYNX. They are:
Flag
LYNX software component that may be set to a logic state to indicate status and
enable/disable functions. Flags may be either system or user-defined.
Immediate Mode
MicroLYNX mode of operation where commands are issued directly from the
terminal to the MicroLYNX.
Instruction
LYNX software component used to direct events inside or outside a program.
Isolated Digital I/O
MicroLYNX programmable I/O. Electrically isolated from motor power ground.
Label
1 to 8 character alpha-numeric name that may be assigned to a program, subrou-
tine, or user-defined variable or flag.
MUNITs
The munit term is derived from the MUNIT, or Motor UNIT variable, which is
the scaling factor by which drive step clock pulses are converted to some unit of
distance measure. The MUNIT variable specifies the number of microsteps per
user unit (inches, degrees, millimeters, etc.). Once MUNIT is established, motion
variables (position, velocity acceleration, etc.) may be expressed in terms of user
units. Almost all the MicroLYNX motion, position, velocity, acceleration and

Party Mode
MicroLYNX mode of operation in which two or more MicroLYNX are net-
worked via RS-485. Each MicroLYNX node has an address specified by using
the “DN” instruction. This address must preceed the messages intended for a
specific node. The default address is the exclamation point character “!”.
Program Mode
MicroLYNX mode of operation where program entry is accomplished.
User Unit
See the definition for munits.
Variable
LYNX software component that acts as a register to contain numeric informa-
tion. May be used to effect events in or out of a program. The programmer is

How to Connect the Motor
There are basically three different lead configurations of stepping
motors with a total of five different wiring configurations.
These are:
8 Lead Motor
Series Configuration
A series motor configuration would typically be used
in applications where a higher torque at low speeds is
needed. Because this configuration has the most induc-
tance, the performance will start to degrade at higher
speeds. Use the unipolar current rating as the peak
output current.
If you need higher torque output
at lower speeds, connect
me in a series configuration.
For higher torque output
at higher speeds use the
parallel configuration!

PHASE B
IMS Inside-Out Stepping Motors
The new Inside Out Stepper (IOS) motors were designed and patented by IMS to
bring versatility to small motors. These motors employ a unique multi-func-
tional, hollow-shaft design. By mounting a miniature ball screw to the front shaft
face, the IOS motor can be converted to a ball screw linear actuator. In addition
to offering long life and high efficiency, ball screw linear actuators may be field
retrofitted. There is no need to throw the motor away due to wear of the nut or
screw.

tions to the MicroLYNX in the following gauges:

Figure 3.2: 8 Lead Motor, Parallel Connection
NOTE: Typically step motor current ratings are unipolar for 8 and 6
lead motors.
NOTE: If bipolar series current is given, multiply by 1.4 to determine
the peak output current.
Parallel Configuration
An 8 lead motor in a parallel configuration yields more torque at higher
speeds than the same motor wired in series. Multiply the per phase (or
unipolar) current rating by 1.96, or the bipolar current rating by 1.4
to determine the peak output current.
6 Lead Motor
Full Coil Configuration
The full coil configuration on a 6 lead motor should be used in
applications where higher torque at lower speeds is desired. This
configuration is also referred to as full copper. Use the per phase (or
unipolar) current rating as the peak output current.

4 Lead Motor
4 lead motors are the least flexible but easiest to wire. Speed and torque will
depend on winding inductance. In setting the driver output current, multiply the
specified phase current by 1.4 to determine the peak output current.

Half Coil Configuration
As previously stated, the half coil configuration uses 50% of the motor
phase windings. This gives lower inductance, hence, lower torque output
at low speeds. As with the parallel connection of 8 lead motor, the
torque output will be increased at higher speeds. This configuration is
also referred to as half copper. In setting the driver output current,
multiply the specified per phase (or unipolar) current rating by 1.4 to
determine the peak output current.

Connecting Communications
One of the features that make the MicroLYNX a unique product is its dual
COMM ports. This allows for simultaneous use of both the RS-232 and the RS-
485 interface. This is especially useful in party mode where several MicroLYNX
nodes are networked in a system. This section will illustrate connecting
your MicroLYNX to a communications host, typically a PC, using a
single MicroLYNX and either the RS-232 interface or the RS-485
interface. For instructions on connecting communications to multiple
MicroLYNX Systems see the product manual.
Tools and Equipment Required
The following tools and equipment are required to connect communi-
cations to your MicroLYNX System:
IMS communications cable part# MX-CC100-00 or equivalent
(if 10 pin header version of the MicroLYNX is used).
Communications cable (if 7 pin terminal version of the
MicroLYNX is used).

When using the RS-232 interface the MicroLYNX must be within 50 feet of the
communications host.
RS-485 Interface
In a system consisting of a single MicroLYNX, the RS-485 interface should be used
if the MicroLYNX will be more than 50 feet from the host PC. Since most PC’s do
not come with an RS-485 interface preinstalled, you will have to install an RS-485

Establishing Communications
Tools and Equipment Required
The following tools and equipment are required to establish communications
with your MicroLYNX System:
IMS LYNX Terminal software.
A free COM port on a PC.
A Personal Computer with a Free COM Port
A PC running Windows 9x, NT4.0 or 2000 is required if the LYNX Terminal
software will be used. However, any operating system that has support for an
ASCII terminal can be used to commu-
nicate with the MicroLYNX.
LYNX Terminal Software
The LYNX Terminal software is
provided to ease programming the
MicroLYNX by combining a text editor and ASCII
terminal. This program is located on the LYNX Product
Family CD and can be installed by running [drive
letter]:\Lynx Terminal\IMS LYNXTerminal.exe. It can also
be downloaded from the IMS website at
www.imshome.com. The minimum system requirements
are:
A 486 or higher PC.
5 MB hard drive space.
Windows 9x, NT 4.0 or Windows 2000.
Installing the LYNX Terminal Software
The LYNX Terminal software is a programming/communications interface.
This program was created by IMS to simplify programming and upgrading the
MicroLYNX. The LYNX Terminal is also necessary to upgrade the software in
your MicroLYNX. These updates will be posted to the IMS website at
www.imshome.com as they are made available.
To install the LYNX Terminal to your hard drive, insert the CD into your CD-
ROM Drive. The 3.5” CD, while smaller than typical compact disks, will work
in any horizontally mounted, tray-type CD drive.
To start the installation click “Start > Run” and type “[Drive Letter]:\LYNX
terminal\IMS LYNXTerminal.exe” in the “Open” box.
Follow the on-screen instructions to complete the installation.
Detailed instructions for the IMS LYNX Terminal software can be located in
The LYNX / MicroLYNX Software Reference Manual.
If you are unable to run LYNX
Terminal, any ASCII Terminal
and Text Editor program can
be used!
