Figure 4-7 Acceleration and velocity characteristic with acceleration reduction: 0 = constant
Hyperbolic characteristic
Figure 4-8 Acceleration and velocity characteristic with acceleration reduction: 1 = hyperbolic
Linear characteristic
Figure 4-9 Acceleration and velocity characteristic with acceleration reduction: 2 = linear
The key data for the characteristic curves equate to:
v
max
= $MA_MAX_AX_VELO
v
red
= $MA_ACCEL_REDUCTION_SPEED_POINT * $MA_MAX_AX_VELO
a
max
= $MA_MAX_AX_ACCEL
a
red
= (1 - $MA_ACCEL_REDUCTION_FACTOR) * $MA_MAX_AX_ACCEL
