Getting started with the high power stepper motor driver

expansion board based on powerSTEP01 for STM32 Nucleo

Introduction

The X-NUCLEO-IHM03A1 is a high power stepper motor driver expansion board based on the

powerSTEP01. It provides an affordable and easy-to-use solution for driving high power bipolar stepper

motors in your STM32 Nucleo project. The fully digital motion control through speed profile generation,

dynamic positioning feedback and a complete suite of protection features offer high levels of

performance and robustness The X-NUCLEO-IHM03A1 is compatible with the Arduino UNO R3

connector and supports the addition of other boards which can be stacked to drive up to three stepper

motors with a single STM32 Nucleo board.

1 Getting started

The X-NUCLEO-IHM03A1 expansion board is a high power stepper motor driver covering

a wide range of applications. In particular, the maximum ratings of the board are the

following.

Power stage supply voltage (VS) from 10.5 V to 50 V

Motor phase current up to 10 A r.m.s.

Follow this sequence to start your project with the board:

1. Check the jumper position based on your configuration (see Section 2: "Hardware

description and configuration").

2. Plug the board to the STM32 Nucleo board through Arduino UNO R3 for the X-

NUCLEO-IHM03A1.

3. Supply the board through the input 1 (VS) and 2 (ground) of the connector CN1. The

power OK (green) and fault (red) LEDs will turn on.

4. Develop your application using the examples provided with the firmware library, X-

CUBE-SPN3, high power stepper motor driver software expansion for STM32Cube.

Further support material is available on the powerSTEP01 (www.st.com/powerstep)

and STM32 Nucleo web pages (www.st.com/stm32nucleo).

Up to three expansion boards can be stacked on the same STM32 Nucleo board

as described in Section 2.2: "Multi-motor configuration".

2.1 Selecting the chip select and clock lines of the SPI

The chip select and the clock lines of the SPI interface can be selected via the appropriate

resistors indicated in Table 3: "Chip select line selection" and Table 4: "Clock line

selection".

2.2 Multi-motor configuration

The expansion boards can be stacked on a single STM32 Nucleo board in order to drive up

to the three stepper motors (one expansion board for each motor is required).

The configuration is changed by mounting the resistors from R3 to R8 as listed in Table 5:

"Multi-motor setup table".

The other resistors are not mounted.

By default, the stepper driver board is configured for a single-motor setup, so the board

configuration must be changed in multi-motor setups before stacking the boards on the

STM32 Nucleo.
