Comments by Timo Karppinen For correct use of the NUCLEO-F401RE, L476RG with the X-NUCLEO-IHM02A1, the solder bridge SB15 on the NUCLEO-x4xxRx has to be removed / Getting started with X-NUCLEO_IHM02A1, page 3/24. = IHM02A1 L6470 nCS

Set the motor parameters before connecting the motor!!! Supply voltage, Maximum motor phase curent and Maximum phase voltage are the most important ones. Set as well the step angle - you will set the number of steps per revolution.

On first tests supply the IHM02A1 voltage from a source where you can set the current limit. The limit should correspond the maximum phase current given in the step motor data sheet. Two phases are driven at a time the current might be double the motor phase current.
