The AxeMotion CNC modules are guaranteed against defects in materials and
workmanship for one full year from the date of purchase.
This warranty cannot apply if electrical connections and prescriptions of use
that are described in this guide have been strictly observed. An installation that
does not comply with these prescriptions invalidates the warranty for conse-
quent damages.
AxeMotion CNC modules are provided without any warranty, even implicit,
concerning the results that can be obtained by their use, or the fact that any
user will be able to run them successfully, or regarding overall satisfaction with
the end products which can be obtained using the modules. The purchaser
explicitly recognises that he/she is solely responsible for choosing this module,
for running and using it and its related software, and for obtaining the actual
results.
Connecting an AxeMotion CNC module requires skills in electrical wiring and
connecting, in motors and power stages, and in computerised motion control.
After integrating a CNC module, it is strongly recommended that the purchaser
begins to get familiar with the machine control by making the first tests on
valueless workpieces.
Strict safety rules exist for building or using an automated machine tool. These
rules must be observed very accurately, and especially for the electrical wiring,
the containment of mobile parts in a protection cabinet, the risks of injury
caused by impacts of chips or fragments of broken tools.
No liability can be accepted concerning the AxeMotion modules, their manufac-
turer or distributor, for direct or indirect damages caused by a misuse or non
complying use, on persons who handle the module or the machine it drives, on
objects or materials subject to machine work, or on computer data subject to
the software processes.
Obviously none of the above terms and conditions may affect your statutory
rights under current law or legislation.

Miscellaneous:
Almost all power stages for stepper motors, and many servodrives are con-
trolled by couples of 5V signals Clock (or Pulse, i.e. rotation of an increment)
and Direction (rotation sense). AxeMotion CNC modules are able to produce
these signals in an intelligent way by receiving and processing high-level
commands that are sent by the supervision software.
The AxeMotion PulseMaker is a complete and high performance computerised
numerical controller that includes advanced functions. Its internal memory
buffer and the availability of different linear interpolation modes render it capa-
ble of producing motion with a rare fluidity, especially in non-circular curves.
Especially developed to be integrated in a motor control rack, it requires some
wiring to connect the miscellaneous input signals (USB connection, axis end
switches, tool measurement, digitising probe, safety system) and output signals
(power stage, spindle control, coolant and other peripheral devices).
Important: the AxeMotion PulseMaker is not opto-isolated, and signals must
be TTL 0-5V strictly. A maximum of 20 mA is allowed on each input and 10 mA
on each output, with a total of 50 mA on all outputs.
Technical data:
-Connection and power supply from USB port (consumption < 90 mA)
-Control for 4 axes, interpolated simultaneously
-Maximum output frequency 35 KHz in interpolation
-Local memory buffer 3.3 Kb (250 commands ahead)
-Interpolations for constant speed, for variable speed, for double ramps
-Management of fast braking along multiple vectors
-Override function for real-time control of speed
-12 inputs, 6 outputs plus the 8 Clock / Dir signals
-Replaceable TTL buffers on output signals (mounted on sockets)
-10 bits analog input (input #8 with binary or analog read)
-10 A / 250 V integrated relay (output #5) with "on" connector
-PWM output for spindle or hot wire control
-Optional 0-10 v / 10 mA analog output, no external power supply required

The XY dimensions of the AxeMotion PulseMaker card are 100 x80 mm and a
thickness of about 25 mm (from solders to power relay).
Unit : mm
It is obvious that the card should not be mounted directly on a metal support
that would shortcut the solders. Use an isolation sheet or, even better, screw
the card at a small distance from the board so the solders do not touch the
surface. Electrical wires and tapes must be soft enough to avoid bending that
can create bad contacts. Also, a USB communication may be working badly if
the cable is too close to a source of electrical noise (motors, power supplies,
neon lights, etc.). Do not place the card itself in the neighbourhood of a possi-
ble source of electrical noise and, whenever possible, integrate it in an iron box
or rack.

Important:before operating any modification in the card wiring, always discon-
nect it from its power-supply (unplug the USB cable and cut the mains of the
power stage and all peripherals).
A poor quality wiring is the cause of recurrent errors. Please take great care of
the integration and the electrical wiring of your AxeMotion card.
The inputs of the PulseMaker card are default "pulled-up" to the +5 V. Conse-
quenly, an input is triggered when connected to the ground (GND) of the card.
Whatever its polarity can be, normally open or normally
closed, a sensor must link the chosen input and the
ground, any other wiring being wrong and not working.
Inputs are dispatched on two connectors, the first one giving access to inputs 1-
8 and the second one to inputs 9-12, each connector providing a GND pin.
Please note that the input #8 can be read as 0-5V binary input (instable state
between 0.8 V and 2.4 V) or as 10 bit analog input. If you have a 0-5V analog
probe, its + pole should be connected to this inputs #8.
The outputs provide a low state (0 V) by default, and a high state (+5 V) when
activated. These outputs are dispatched on two connectors, the first one giving
access to motor signals Clock / Dir, and the second to outputs that can drive
peripheral devices, each connector providing a ground (GND) pin. Please note
that the outputs #6 can be used as binary or PWM output (which controls the 0-
10 V), and the output #5 is available on its connector but also triggers the
power relay with its separate connector.
The USB connection can be taken either from the classic USB-B connector, or
on its neighbour pins. Please be careful with the signals.
Reminder: inputs and outputs are not opto-isolated and accept 0-5V TTL
levels only. Furthermore, the outputs can provide a maximum current of 10 mA
each, and a maximum of 50 mA for the whole set. Consequently, a bad con-
nection or a too heavy load may damage the card, or even the host com-
puter. So it is extremely important to make sure that the peripheral devices that
the card will drive are correctly isolated and do not need too much current.
AxeMotion provides the PulseMaker cards either with screw connectors (stan-
dard), or HE10 connectors (optional) for wire tapes.

Important:connections differfor the
AxeMotion PulseMaker version that is
fitted with HE10 male connectors with
double rows of pins and locator which
require female connectors to be
clipsed on wire tapes.
Warning, the list of numbered
signalson a wire tape will not be
the same wether you have a HE10
or a screw connector.
Inverting motor signals or outputs will
not cause any damages to the card or
the power stage, provided that this
inversion does not concern the ground
(GND pins). Simply, the connected
motors or peripheral devices will not
work. On the other hand, inverting
the GND and a signal destroys the
74LS541 output circuit. Fortunately,
this chip is mounted on a socket so
you may replace it easily in case the
wiring was wrong. Inverting the GND
with the +5 Vcc on a peripheral may
damage the host computer.
Much less serious, inverting input
signals, including with the GND pin,
will not cause any damages except a
simple malfunction of the manage-
ment of the sensors or any peripheral
devices that are presumed to return
information to the card and its
supervising software.
If you do not wish to plug the communication cable directly in the standard
USB-B connector because the card has been integrated in a cabinet, then you
may use instead the neighbour 4-pin connector that
reproduce the USB signals. In such case, it is very
important to carefully check the wiring of these
signals: a wrong connection on the USB signals
may seriously damage the card and the host
computer. To help you find the correct signals, the
wire colours in USB cables are standard. Unfortunately, the connection plug on
the board with only four pins cannot provide a locator. So, be very careful not to
invert the connection.
