Introduction
The L6480 and L6482 devices are motor controllers providing a flexible solution for the high
power stepper motor applications. The devices can be controlled by a host microcontroller
through a fast SPI interface and are able to execute a complete set of motion commands.
This document describes how the devices can be configured and gives some suggestions
on the operation and application design.
The current control algorithm of the devices - voltage mode driving for the L6480 and the
advanced current control for the L6482 device - will be not investigated in this document.
Please refer to the respective application notes AN4144 “Voltage mode control operation
and parameter optimization” and AN4158 “Peak current control with automatic decay
adjustment and predictive current control: basics and setup” for more details about them.
