MotCurrRegVltgLimrInit1
INIT: MotCurrRegVltgLimrInit1
Design Rationale
Design follows implemenetation in FDD.
Module Outputs

PERIODIC FUNCTIONS
INIT: MotCurrRegVltgLimrPER1
Design Rationale
Module Outputs
As per FDD, dMotCurrRegVltgLimrMotVltgDecouplFbDax, dMotCurrRegVltgLimrMotVltgDecouplFbQax renamed with dMotCurrRegVltgLimrMotVltgDecoupldFbDax, dMotCurrRegVltgLimrMotVltgDecouplFbQax in the source file. And also dMotCurrRegVltgLimrMotCurrCmdErr(display variable) is nowhere used in source file. That variable davinci definition is removed. Design follows implemenetation in FDD.
