2. DGF OVERVIEW
2.1 INTRODUCTION
DGCF is a general purpose, where the final user can load the custom firmware which
carry out the desidered applications.
The DGF option is mounted on the drive with which it communicates through a DUAL
PORT RAM. Therefore it is possible to read drive parameters (including parameters
connected to analog and digital I/O), perform the algorithms, and write the result or
other parameters necessary to realize the desired functions.
The functional blocks also allow the reading of inputs and writing of outputs, physically
present on the optional I/O card and available to the DGF.

2.1.1 Firmware organization
The firmware of the DGF is divided in two parts: a fixed part, factory developed, and
a personalized one which can be developed even by the final user.
The final user has different possibilities to personalize the firmware of the DGF. The
main tools are the developing environment Win+Drive. Users with a programming
knowledge can develop directly with a C or Assembler language.
