Getting started with STM32 Nucleo Pack
Introduction
The NUCLEO Pack (P-NUCLEO-IHM001) is a motor control kit based on X-NUCLEOIHM07M1 and NUCLEO-F302R8. The power board with ST L6230 DMOS driver, belonging
to STPIN family, provides a motor control solution for low voltage 3-phase DC brushless
motor with the addition of STM32 NUCLEO-F302R8 board, connected through ST morpho
connectors.
This document describes the hardware environment to build the system and run an
application based on the P-NUCLEO-IHM001 motor control kit.

System architecture
A generic motor control system can be basically schematized as the arrangement of three
main blocks (see Figure 2: System architecture):

Control block: its main task is to accept user commands and configuration parameters
to drive a motor. The P-NUCLEO-IHM001 is based on NUCLEO-F302R8 board that
provides all digital signals to perform the proper motor driving control algorithm (for
instance 6-step or FOC):
–
The original firmware demonstration, to reprogram the STM32 MCU of the PNUCLEO-IHM001, is available from ST web site www.st.com, in binary file format
called 
P-NUCLEO-IHM001.bin.
–
FOC solution is based on the STM32 PMSM FOC SDK software development kit
(SDK): STSW-STM32100.
–
6-step solution is based on 6-step motor control library: X-CUBE-SPN7.

Power block: the X-NUCLEO-IHM07M1 is based on 3-phase inverter topology. The
core of the power block embedded on board, is the driver STSPIN L6230, which
contains all the necessary active power and analog components, to perform a low
voltage PMSM motor control.

PMSM Motor: low voltage 3-phase brushless motor.
Figure 2. System architecture
An external power supply (from 8 V min to 12 V max, able to delivered 1 A min) is required
to power the kit.

How to build and run the motor control Nucleo Pack
The P-NUCLEO-IHM001 is a complete hardware development platform (Power & Control
block + Motor) for STM32 Nucleo ecosystem, to evaluate a motor control solution for single
motor. For a regular board operating, follow the hardware configuration shown below:
1.
The X-NUCLEO-IHM07M1 must be stacked on the NUCLEO-F302R8(a) board through
the ST morpho connector. There is only one position allowed for this connection, in
particular as shown in Figure 3 the two buttons on NUCLEO-F302R8 board (blue B1
and black B2) must be kept out.
Figure 3. X-NUCLEO-IHM07M1 and NUCLEO-F302R8 assembled
a. The interconnection between the X-NUCLEO-IHM07M1 and NUCLEO-F302R8 boards has been designed for
a full-compatibility with a lot of control board and no modification of solder bridges is required.

2.
Connect the three motor wires U,V,W at J2 connector as shown in the Figure 4: Motor
connection with X-NUCLEO-IHM07M1: it is mandatory to connect the white or yellow
wire to OUT1, the black one to OUT2 and the red one to OUT3, to respect clockwise
and counterclockwise motor rotation, according to the firmware implementation.
Figure 4. Motor connection with X-NUCLEO-IHM07M1
1. The three motor wires are identified by a colored line, marked on them. The line marked on OUT1 (refer to
the white arrow in the above figure) can be white or yellow.
3.
Select the jumper configuration on the power board to choose the desired control
algorithm (6-step or FOC) as described below:
a)
On NUCLEO-F302R8 board, check jumper setting: JP1 open, JP5 (PWR) on E5V
side, JP6 (IDD) closed.
b)
On X-NUCLEO-IHM07M1 expansion board:
–
Check jumper settings: J9(b) closed, JP3 closed
–
For 6-step control, set jumpers as: JP1 and JP2 open, J5&J6 on 1Sh side(b)
–
For FOC control, set jumpers as: JP1 and JP2 closed, J5&J6 on 3Sh side(b)
For details refer to Figure 5: X-NUCLEO-IHM07M1 – top layer with silk-screen and Figure 6:
X-NUCLEO-IHM07M1 connectors view.
Note:
FOC algorithm gives better performance than 6-step one.
b. It is important that supply voltage is powered off before control mode changing.

Connect DC supply voltage on J1(c) connector and power-on (up to 12 V DC for
BR2804 motor included in the Pack, as shown in Figure 7: Power supply connection for
X-NUCLEO-IHM07M1).
Figure 7. Power supply connection for X-NUCLEO-IHM07M1
5.
At power-on (or reset) led D11 on X-NUCLEO-IHM07M1 board starts to blink,
according to the control algorithm choice:
–
2 times for FOC mode control
–
4 times for 6-step mode control
After the confirmation of the control algorithm selected, the system is ready to start.
6.
Push the blue button on NUCLEO-F302R8 board (B1) and the motor starts to spin.
7.
Rotate the potentiometer on X-NUCLEO-IHM07M1 board to regulate the motor speed.
For more details refer to UM1945 at www.st.com website.
c.
10/12
For a different motor (>12V) it is mandatory to remove the jumper J9 on power board, before the power-on, to
avoid to damage the NUCLEO-F302R8 board. To supply the STM32-NUCLEO from USB, the jumper JP5 must
be connected between PIN 1 and PIN2. For further details on Nucleo settings refer to UM1724 available from
ST web site www.st.com.
