Message Operation
A BRAM Store saves the function block program that is currently in
RAM to the function block BRAM/EEPROM.
A BRAM Recall copies the function block program that is stored in
BRAM to RAM. The drive executes the program stored in RAM.
A BRAM Initialize erases the function block program stored in
RAM and all associated function block links including links to linear
drive parameters. A BRAM Initialize function does not actually
clear out the BRAM itself; it only clears the function block
application out of the working RAM area.
Refer to Chapter 3 for a more detailed description of BRAM
functionality.
