Safety Instructions
The MDLCNC stepper motor driver may only be installed and commissioned by
qualified personnel. Please read the operating instructions carefully and follow
all instructions exactly. Improper installation or operation of the device can cause
damage to the electronics or the machine and can result in dangers to the health
of the operating personnel. The system manufacturer, who assembles the power
amplifier and other components to form the overall system, and the system
operator are responsible for compliance with the legal regulations.
Caution: Danger to life! The device can be operated with voltages up to 230V
(relay outputs). If you operate the system with more than 60V, the installation
and commissioning may only be carried out by a trained electrician or must be approved by
such an electrician. No liability is accepted for damage or injury resulting from failure to
observe the safety regulations or improper use.
Always use a power supply unit with potential separation (no autotransformer or variac)!
Machine, motor and housing must be grounded according to the regulations.
System requirements
To obtain a functional drive system, the following components are required in addition to the
MDLCNC driver:
One to four two-phase stepper motors with a rated current between 0.5 and 4.5A. Three- or
five-phase motors or high-impedance motors from printers and disk drives are not suitable.
A power supply unit for the power supply. with an output voltage between 18 and 36V
Stabilization is not absolutely necessary. More detailed selection criteria are given in chapter
3.2.
A PC with the Beamicon2Basic software installed (to select the PC and operating system
please refer to the Beamicon2 software user manual), and a Micropod2 with firmware for the
MDLCNC driver. This firmware is included with the Beamicon2Basic and can be loaded later
(see Installation Software).

Assembly
For mounting it is recommended to replace the 4 screws in the corners with longer ones and
to mount the board with non-conductive spacers. Another possibility is the mounting with 4
small brackets (see picture). For this purpose M3 screws are screwed between the cooling
fins. If necessary, the distance between the cooling fins can be bent to fit.

Setting the motors
Setting the motor current
Attention: Make sure to set the correct phase
current before you switch on the power supply.
Too high a current - even for a short time - can
damage the motor. If you do not need the full
torque of the motor, you can also set a slightly
lower current. This significantly reduces heat
generation. However, do not set less than 70%
of the rated current, otherwise the motor may
not run smoothly.
The phase current of the motor is adjusted with
the small blue control dial. Use a small
screwdriver for this. The regulator is very easy
to turn, do not use force. In the picture on the
right the regulator is now at 4.5A. You can set
any value, the adjustment is linear.
Setting the microsteps
The microsteps are set by means of the dip switch (the black box with the white levers in the
picture above right). Please set the switch as shown in the photo. This corresponds to 16
microsteps.
Connection of the motors
The motors are connected to the sockets X-axis to 4th axis. Where A+ and A- is one coil of
the motor and B+ B- is the other coil of the motor. If you do not have a data sheet at hand,
you can quickly test it with a multimeter. There must be continuity between the terminals of
one coil, the other two terminals must not have continuity. It does not matter which coil you
connect to A and B. It also does not matter how the coil is connected (i.e. A+ and A-
reversed). It is only important that between A+ and A- is one coil and between B+ and B- is
the other coil.
Use a shielded cable to connect the stepper motors and connect the shield to the ground of
the control cabinet.
Meaning of the LEDs
The two LEDs near the FI-Interface
indicate that the device is ready for
operation.The four LEDs in the middle of
the board indicate the control signals from
the PC for the 4 motors.

The LED near the relay connector indicates the control signal for the relay.
Connection of the reference switches and emergency stop buttons
The reference switches can be connected to the socket below the micropod and an
emergency stop button must be connected.
The reference switches and the emergency stop button are connected to ground (GND) and
are closed in the idle state. So in an emergency, you can also detect a broken cable.In
addition to mechanical limit switches, inductive limit switches of type NPN can also be
connected. The power supply is provided via the terminals 0V and 12V.

Attention! The emergency stop button is not the only safety feature. Depending on the
hazard potential of the machine, additional safety measures may be required, such as door
interlocks and standstill monitoring. As a rule, such safety functions must
be implemented purely electromechanically with external circuits (not
included in the scope of delivery) and must not depend solely on
software and PC hardware. The system manufacturer, who assembles
the interface board and other components to form the overall system,
and the system operator are responsible for compliance with the legal
regulations.
Relay 1
Unfortunately, relay1 is connected incorrectly and is energized when the machine is
deactivated and the emergency stop circuit is activated. It cannot therefore be used to switch
a spindle, as it can tighten/drop uncontrollably in the event of an emergency stop or when the
control is switched on.

The use of the relay for non-critical tasks is however (limited) conceivable.
If a relay is required to switch on a spindle, the FU module must be used.
Power supply 18-36V
A voltage of 36V is recommended, even for small machines. Since with a higher voltage a
higher speed of the motors can also be achieved. The design of the power supply unit
depends on the number of connected motors and their current consumption. If you are not
able to design the power supply yourself, please consult your dealer. Often there are also
complete sets with motors and power supply.
Attention! Pay attention to correct polarity of the supply voltage !

Connecting the Micropod
The micropod is the heart of the controller. It contains a powerful 32bit microcomputer with 8
cores. This takes over the calculation of the steps and ramps and evaluates the reference
switches and 3D probes. The connection to the PC is made via an Ethernet cable.The
micropod requires 5V operating voltage. These can be removed from the connector of the FI
module.
Safety Instructions
The interface module may only be installed and put into operation by
qualified personnel. Please read the operating instructions carefully and
follow all instructions exactly. Improper installation or operation of the
device can cause damage to the electronics or the machine and can
result in dangers to the health of the operating personnel.
Depending on the hazard potential of the machine, additional safety
measures may be required, such as door interlocks and standstill monitoring. As a rule, such
safety functions must be implemented purely electromechanically with external circuits (not
included in the scope of delivery) and must not depend solely on software and PC hardware.
The system manufacturer, who assembles the interface board and other components to form
the overall system, and the system operator are responsible for compliance with the legal
regulations.
Reversing the polarity of the operating voltage of 5V at X1 can permanently damage
the module and is not a warranty case.

Network / PC
LPT1 (SUBD-25)
Functional description
The MicroPod is in a way an "intelligent external LPT interface card". Unlike PCI plug-in
cards with LPT port or LPT interfaces integrated on the PC motherboard, the MicroPod has a
built-in, powerful 8-core 32-bit processor that is optimized for generating step/direction
signals and also calculates S-shaped acceleration ramps. This is otherwise only known from
expensive industrial controls. The PC is not burdened with this task, but only has to send
coordinates to the MicroPod at regular intervals via a network interface (Ethernet IEEE802,
10MBit/s). All time-critical operations run in the MicroPod, so that the PC is relieved and is
only needed for the user interface.
Much higher step frequencies (1.6MHz) are possible than with LPT port-based solutions, and
the timing is precise and reliable. Compromises in the selection of the resolution in
connection with the maximum possible speed are therefore no longer necessary. Servo
drives can also be operated with high resolution and speed. Step losses due to short
"dropouts" of the PC or too "low performance" PC are excluded. Similarly, errors of the
operating system, such as Windows, do not affect the speed or precision.
Even for the user difficult to understand setting of the pulse duration and distance is
completely omitted. The MicroPod always generates the step signals with a perfect duty
cycle of 50%. Changes of direction always occur exactly in the middle of the pauses between
clock pulses. This ensures that the maximum pulse duration is always output in accordance
with the frequency. Violations of the setup and hold time by simultaneous change of step and
direction signal state are avoided.
PC / network connection
The data transfer from the PC software to the MicroPod takes place via an Ethernet network
connection (IEEE802.3 10BASE-T). The connection can be made with standard patch cables
to the RJ45 socket ST1.
In contrast to similar products from competitors (e.g. Smoothstepper or Eding-CNC) no
exclusive interface has to be reserved on the PC, but the infrastructure of an existing network
with switches can be used. There is also no need to change IP addresses or otherwise
interfere with the Windows Control Panel. The Beamicon2 software automatically detects the
MicroPod, even if it is connected "somewhere" in the network. To ensure reliable operation,
however, the following rules must be observed:
The MicroPod must be connected either directly to the PC or to the first switch after the PC.
A further switch may only be added if only devices of the machine are connected to the
second switch, e.g. within the control cabinet of the machine. All devices not involved in
machine control (Internet router, printer, NAS, etc.) must be connected to the first switch or to
additional switches behind the first.

The transmission speed between the PC and the first switch must be higher than the
maximum data rate of any existing Internet
routers (DSL modem, etc.). For home
networks with few PCs 100MBit is
recommended, for larger networks Gigabit-
Ethernet.
Since no TCP/IP is used but a separate
protocol, this cannot be forwarded by routers,
external firewalls, proxies, etc. Therefore only
so-called "unmanaged switches" may be used
between the control PC and the MicroPod.
Switches must support Fast Forward and
Store-and-Forward (virtually all modern
switches meet this criterion)
Hubs are also allowed for test purposes
(listening with diagnostic tools on taps), but
are not recommended.
The data traffic of the machine controller must
not be routed via slow (DSL modem) or
unreliable (wireless) connections (WLAN). All
wireless interfaces are therefore intentionally
hidden.
If the MicroPod is connected directly to the
PC and the PC interface does not support automatic crossover, a crossover cable must be
used (usually marked with a red connector or "X"). The network interface is galvanically
isolated from the PC. Power-over-Ethernet (PoE) is not supported.
Power supply
The MicroPod can be supplied with an operating voltage of 4.5 to 6V DC. The input is not
protected against accidental reverse polarity. The connection is easy
to make at the socket for the FI extension. Connect the 5V from the
micropod to terminal 5V from the connector of the FI-extension and the
ground (GND, 0V) to terminal GND of the FI-extension.
Check the cabling again before switching on.

Configuration
Note: If you have NOT purchased the Micropod in combination with a power amplifier
MDLCNC, you will have to make a firmware update of the Micropod to ensure correct
function. The firmware update is very easy and described in the Beamicon2 software
user manual. To do this, select the firmware "MicroPod
Benezan_V131_Letmathe.binary" and follow the instructions.
The assignment of the inputs and outputs is done in the Beamicon2Basic software. The
installation and operation of the software as well as the setting of the machine parameters is
described in detail in the Beamicon2Basic software manuals. Therefore only the special
features of the MicroPod will be discussed here. The easiest way of configuration is to select
the default parameter set "Default_MicroPod MDLCNC" when starting the software for the
first time. Then you do not have to make all settings again, but only enter the deviations from
the standard values. You can also load the default values later by selecting "File -> Import
settings" from the menu and clicking "Default parameters".
After the first start, the MicroPod must first be connected. If the hardware dialog does not
open automatically, you can do this in the menu under "Configuration -> Hardware". Select
the module and then click on "connect" and "save".
The step and direction signals for up to 4 axes are automatically assigned to pins 2 to 9 of
the SUBD connector for LPT1. No settings need to be made for this. In particular, there is no
need to set a pulse time, as the step signal always has a 50% duty cycle. The direction of
movement can be reversed in the machine parameters (Menu -> Configuration -> Machine)
on the "Axis Parameters" page with the "Inverted direction" button.
For the assignment of the signals switch to the page "Inputs/Outputs". Actually all
outputs/inputs including the FI module are already set. Only if the reference switch of the 4th
axis is not needed, it can be assigned to a 3D probe or tool length sensor, for example.
The following inputs/outputs are permanently assigned and cannot be changed:-LPT1 Pin 11
is permanently reserved for the emergency stop input.-The PWM output can only be
assigned to either LPT1 pin 1 or LPT1 pin 17.-The step/direction outputs cannot be changed.
Input signals can be used multiple times if required. For example, the same switch input can
be used simultaneously as a reference and limit switch.
In contrast to inputs, output signals cannot be inverted (active low/hi) because otherwise the
safe off state would not be defined.
If the number of available outputs or inputs is not sufficient for the application, they can be
expanded as desired with an I/O-Ext expansion module from Benezan-Electronics.

FU module
Description
The FU module is an expansion board which is connected to the "FU module" expansion
connector of the power amplifier. It can also be used with other breakout boards.
The board is used to convert the PWM signal, which is provided by the controller, into an
analog signal of 0-10V. This is required to control a frequency converter. There is also a
relay on the expansion board which can be used to switch on the frequency converter or a
spindle directly.
The relay has a changeover contact / changeover switch which can be loaded up to 230V
and 6A.
Caution: Danger to life! If the relay is operated with more than 60V, the
installation and commissioning must only be carried out by a trained
electrician or must be approved by such an electrician. No liability is
accepted for damage or injury resulting from disregard of safety
regulations or improper use.

Hint: By plugging in the "FU module" expansion module, the electrical isolation of the 5V and the
operating voltage of the output stage is removed. This is absolutely no problem and poses no risk, as
the galvanic isolation to the PC is provided by the micropod. By using the micropod, breakout boards
and power amplifiers do not need to have galvanic isolation.
Attention! The connections for the operating voltage "+5V" and "+12V" are
not protected against reverse polarity! Make sure that the connection is
correct.
Connect the output "0..10V" together with the connection "GND" according to the manual of
your frequency inverter. The output is short-circuit proof and safe against accidental
application of a voltage up to max. 31V. This will destroy the module.
The relay can be used to switch the input for spindle forward of your frequency converter.
Please refer to the manual of your frequency inverter.
