Name Description
2020h 1 Speed Control Mode 4 = Speed control with PDO controlled ramp
5 = Speed control with parameter controlled ramp
2020h 7 Rollback Speed 0-8000 rpm
Controls if the truck stands still or starts rolling when
slowing down to zero speed in an slope. Setting the
speed to zero means stand still (hillhold). Only used in
speed control modes with ramps (Speed Control Mode
= 4 or 5).
2020h 10 Application Setup Word Bit 0 Adjust Speed During Acceleration
If set to true, the truck may accelerate faster
than the ramp says, if accelerating in an
steep downhill slope.
Bit 1 Adjust Speed During Deceleration
If set to true, the truck may decelerate faster
than the ramp says, if decelerating in an
steep uphill slope.
Bit 2 Enter Rollback Mode At Zero Speed
If set to true, the truck stops before it
eventaully starts to roll. Only used if
Rollback Speed is NOT zero
2095h 9 Speed Change Shift
Factor Rigth shift of Acceleration/Deceleration values.
Changes the scale of the ramps, i.e.
from:
0->255 rpm/20ms
to: (0->255)/2
n
rpm/20ms
where n = Speed Change Shift Factor
2096h 4 Used Max Forward

ASICS
The basic speed ramp functionality is shown in Figure 23 . When a step change in the Command
Speed is sent to the ACS the Internal Speed Reference value is ramped from the previous
Internal Speed Reference speed value to the new Internal Speed Reference.
