Getting started with STM32 Motor Control Nucleo Packs

P-NUCLEO-IHM001 and P-NUCLEO-IHM002

Introduction

The Nucleo Packs P-NUCLEO-IHM001 and P-NUCLEO-IHM002 are motor control kits

based on X-NUCLEO-IHM07M1 and NUCLEO-F302R8 boards. 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 the STM32

NUCLEO-F302R8 board, connected through the ST morpho connectors (see Figure 1).

The P-NUCLEO-IHM002 Packs comes with a power supply unit (see Figure 2).

This document describes the hardware environment to build the system and run an

application, based on the P-NUCLEO-IHM001 and P-NUCLEO-IHM002 Nucleo Packs.

1 Getting started

1.1 System architecture

A generic motor control system as the P-Nucleo-IHM001 or the P-Nucleo-IHM002 can be

basically schematized as the arrangement of three main blocks (see Figure 3 and Figure 4):

•Control block: its main task is to accept user commands and configuration parameters

to drive a motor. The P-Nucleo-IHM001 and the P-NUCLEO-IHM002 Nucleo Packs are

based on the 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

P-NUCLEO-IHM001, is available in binary file format from the www.st.com

website and it is 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.

The P-Nucleo-IHM002 has a fourth block:

•DC Power supply unit: it provides the power for this Nucleo Pack (12 V, 2 A).

1.2 How to build and run the motor control for the STM32 Nucleo

Packs

The Nucleo Packs are complete hardware development platforms for the STM32 Nucleo

ecosystem, to evaluate a motor control solution for single motor.

For a regular board operating, follow the hardware configuration explained below:

1. The X-NUCLEO-IHM07M1 board must be stacked on the NUCLEO-F302R8 board

through the ST morpho connectors. There is only one position allowed for this

connection, in particular the two buttons on the NUCLEO-F302R8 board (the blue B1

and the black B2) must be kept out, as shown in Figure 5.

Figure 5. X-NUCLEO-IHM07M1 and NUCLEO-F302R8 assembled

1. The interconnection between the X-NUCLEO-IHM07M1 and the 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 6: Motor

connection with X-NUCLEO-IHM07M1: it is mandatory to connect the yellow wire to

OUT3, the black one to OUT2 and the red one to OUT1, to respect clockwise and

counterclockwise motor rotation, according to the firmware implementation.

3. Select the jumper configuration on the power board to choose the desired control

algorithm (6-step or FOC) as described below:

a) On the NUCLEO-F302R8 board, check jumper settings: JP1 open, JP5 (PWR) on

E5V side, JP6 (IDD) closed.

b) On the X-NUCLEO-IHM07M1 expansion board:

– Check jumper settings: J9(a) closed, JP3 closed

– For 6-step control, set jumpers as: JP1 and JP2 open, J5 and J6 on 1Sh side(a)

– For FOC control, set jumpers as: JP1 and JP2 closed, J5 and J6 on 3Sh side(a)

For details refer to Figure 7: X-NUCLEO-IHM07M1 – top layer with silk-screen and Figure 8:

X-NUCLEO-IHM07M1 connectors.

Note: FOC algorithm gives better performance than 6-step.

a. Supply voltage has to be off before changing the control mode.
