2. Safety instructions
Power supply and grounding requirements. Connection to controller
General requirements for a controller board, systems in box ( single and double axes) are listed below.
IMPORTANT. Either the power supply unit should be plugged to grounded 220V AC socket (a three-wire connection
scheme). Make sure that the minus electrode of your power supply unit is grounded. If the power supply unit with
minus electrode disconnected from the grounding circuit is used, ground the controller board via special grounding
terminal (look at the picture below). Non-compliance with these rules may lead to the decrease in controller stability
and noise resistance.

Warning. Power supply unit should be able to supply sufficient current to rotate the motor. As an absolute minimum
it should be able to supply where is the minimum working current of
power supply unit, is the operating current in the winding, is power supply unit stabilized voltage, and
is rated operating voltage of the motor. It is recommended to use a power supply unit with operating current
equal to . The voltage should be greater than . The higher the voltage, the
faster rotation speed could be reached.
One can use power consumption of power supply unit to calculate minimum requirements instead. An absolute
minimum of power is . For example, for motor with
operating winding current of 1A and operating voltage of 5V (with 5W rated power consumption), the operating
voltage of power supply unit may be chosen at 20V with the output power of at least 10W (the maximum operating
current of power supply unit is at least 0.5A).
Controller board
IMPORTANT. It is strictly forbidden to touch the controller board without any antistatic equipment. We recommend
you to use antistatic wrist strap.
IMPORTANT. It is strictly forbidden to connect positive wire of power supply to the controller board when
ground wire is not connected. It is strictly forbidden to connect or disconnect power cable when the
power supply is on, the controller is connected to the PC and the power supply and the PC are grounded.
This may damage the PC! This is a common requirement for any electronic device with separate power source,
which is connected to the PC via USB.
Warning. Before connecting the controller board to the motor or to the PC via USB interface, it is recommended to
connect controller to power supply with proper grounding or to use separate grounding for controller with the specially
marked ground terminal (look above).
One and two axes system in box
IMPORTANT. You should not exceed maximum allowed voltage of 48V. If voltage goes over allowed value at
more than 2 volts, it can immediately and irreversibly damage the controller.

Xilab software is a convenient way to control stages connected to 8SMC5-USB controller. However, if you need to control the 8SMC5-
USB from your own application, you may do so by using libximc library. Programming guide 8SMC5 has several examples in C, C#,
Delphi, Java, VB.net, Matlab, LabView programming languages. If all you need is to automate a small number of control steps, then
instead of a standalone program you may find it easier to use Xilab scripting language.

3.2. Example of a motor connection
General case
To connect a motor to the controller please refer to positioner connector, and
use the scheme of positioner connection:
Positioner standard connection diagrams
General diagram of positioner and encoder connection using Dsub connector.
Note. If A and B encoder channels work in open drain mode, some extra pull-up of encoder outputs to 5V power
voltage using the resistors may be required at high rotation speeds in order to provide the maximum signal
transmission speed (see Operation with encoders ).
Note. Only firmwares 4.1.0 and older support BLDC.
Example
Consider the connection of the two-phase stepper motor Nanotec ST5918L3008-B with encoder CUI INC AMT112S-V to controller
8SMC5-USB.
Preparation
To get started, we need:
Motor;
Encoder;
Pinout of D-SUB connector for 8SMC5-USB;
Motor datasheet ;
Encoder datasheet ;
Soldering equipment: soldering-iron, wires, flux, solder, nippers, heat shrink tubes of different sizes;
Screws M2.5x6 for fixing the encoder;

Connecting the motor and encoder to the controller
Before you begin, assemble the encoder in accordance with the appropriate instructions.
The motor without encoder. Note 2 holes M2.5 to which is usually attached an encoder
Motor with attached encoder
Let us look in the specification of the engine and find the wiring diagram (for Nanotec ST5918L3008-B it is at the bottom right in
the specification):
Motor contacts
Connection type
There exist serial and parallel winding connection and each type allows to obtain various characteristics for the motor. We
will connect the windings in series (red frame on the picture). To do this, wires having two colors BLK/WHT and GRN/WHT,
as well as RED/WHT and BLU/WHT must be connected to each other in pairs. Next, you need to put in accordance A, not A,
B, not B pins of controller to contacts of motor windings ST5918L3008-B: black, green, red, blue. One winding is a
connection of A and not A or B and not B. After the connection between a two-color wire, you will get that one winding of
the motor is black - green connection, other is red - blue. Therefore, matching contacts will be the follows: black - A, green
- not A, red - B, blue - not B. It can be seen in the picture above Connection type.
