How to drive multiple stepper motors with the L6470 motor driver
Enrico Poli
Introduction
The L6470 is a flexible device for the driving of bipolar stepper motors in multiple motor
systems. This application note describes how to drive three bipolar stepper motors in
a daisy chain configuration. Each motor position and its velocity can be controlled
individually or a sequence of position and velocity commands can be implemented by using
the IronPython scripting language included in the dSPIN™ evaluation tool. With the dSPIN
evaluation tool and STEVAL-PCC009V2 interface board, up to eight stepper motors can be
controlled in a daisy chain configuration.
