This parameter applies to the speed limits whenthe override bit P770 [PTP Control] Bit 0 “Vel Override” is on.789 PTP EGR MultPoint-To-Point Electronic Gear Ratio MultiplyEGR multiplier (numerator) for position index output. The output applies to thepoint-to-point command P784 [PTP Command].790 PTP EGR DivPoint-To-Point Electronic Gear Ratio DivideEGR divider (denominator) for position index output.
