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
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"
