Brushless motors and servodrivers

A friend of mine, owner of a company that uses a lot of motors, was very kind and gave me two high performance bruschless motors. With this motors we intend to drive the right ascension and declination of the telescope.

The motors are equipped with a resolver that allows to control the motor position to less than a tenth of a degree. 

Then we purchased two Infranor servo drives capable of driving these motors through the Ethercat fieldbus with DS402 profile.

Now we need the controller for the initial tests.

Introduction

Hello everyone, the Bassano Bresciano observatory (code 565) has been fully automated and remote controlled for some time. It can work automatically all night without the presence of operators and can be remotely controlled. Now the growing needs require a rethinking of all parts of automation. We open this blog with the intention of publishing all the steps that we will perform in this modernization operation allowing anyone to access projects and software in the hope that they will be useful.
