The DGFC communicates to the DRIVE through a device called DPRAM. This device allows the
write or read from the parameters of

DRIVE, and consequently to condition its functioning. In DPRAM

there are various communication structures with different functioning modes.
The structure piloted by the IDA block carries out a reading operation of DGFC from the

parameters.

The maximum number of parameters to be controlled by this structure is 10. The reading of the parameters
occurs in an asynchronous way compared to the regulation cycle.

The communication structure is composed of ten slots. Inside each

slot

3 data are contained:

l

Identifier of DRIVE parameter

l

T Y P E

Type of DRIVE parameter

l

VALUE

Value to be read from the parameter specified by

During the transition of DGFC from

the communication structure is configured:

l

DGFC copies

parameters in the

field of the respective slots.

l

DGFC requires the

to carry out the configuration of the communication structure.

l

The

analyses the parameter identifiers in the

field and if it finds them in compliance with

each other, it writes the type of the required parameter in the

TYPE

field. The TYPE field will be used

during the communication to perform the automatic conversion of data.
