5.1.14 vl_velocity_acceleration (Index: 6048h)

The vl velocity acceleration index specifies the slope of acceleration ramp for RFG. (32bit length)

It is generated as the quotient of the delta speed(Sub-index1) and delta time(sub-index2) sub-

index.

Sub-index1 = delta speed (unit: min

-1

Minimum unit: 1dig= 1min

-1

)

Sub-index2 = delta time (unit: sec Minimum unit: 1dig= 1sec)

vl_velocity_acceleration = delta_speed / delta_time

This Index is effective only RFG mode.

5.1.15 vl_velocity_deceleration (Index: 6049h)

The vl velocity deceleration index specifies the slope of deceleration ramp for RFG. (32bit length)
