VI0135
The DGFC communicates to the DRIVE through a device called DPRAM. This device allows the DGFCto
write or read from the parameters of the 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 DMVE 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 IPA Identifier of DRIVE parameter
l TYPE Type of DRIVE parameter
l VALUE Value to be read from the parameter specified by IPA
During the transition of DGFC from IDLE->RE%DY the communication structure is configured:
l DGFC copies IPAO..IPA9 parameters in the IPA field of the respective slots.
l DGFC requires the DFQVE to carry out the configuration of the communication structure.
l The DEUVE analyses the parameter identifiers in the IPA 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.
