Hello @ALupo.1 and welcome to the ST Community.

The red LED indicates that at least one of the two devices is in fault condition.

As described in the L6470 datasheet at the end power-up, the FLAG output is forced low.

It is necessary to send a GetStatus command to reset the STATUS register flags.

Let me know if this info help you.
