Implementation

Introduction

This chapter describes how to initialize, parameterize, program, and start up the

system.

Function

Functional description

1. The entire island is controlled via the PLC. For this purpose, the STB and FTB

input and output values are transferred between Advantys STB and the PLC,

along with the ATV31 state values. On the PLC, there is a state machine for the

DriveCom profile available for each ATV31. The variable speed drives are

controlled via these state machines. The state machine converts motion

commands, e.g., “Turn left at 1400 rpm” or “Acknowledge error”, into a control

signal for the drive.

2. In the example project, the motion commands are generated using an operator

panel in the Unity PLC programming software. Here the user can control the

drives by pressing buttons and entering a speed. The drive island I/O signals can

be used as an alternative to manual operation via the operator panel. In this

case, setting certain inputs will generate a motion command.
