Parameterization

The knee-shaped acceleration characteristics can be activated specific to the machine axis via the machine data:
MD35240 $MA_ACCEL_TYPE_DRIVE = TRUE
The knee-shaped acceleration characteristic curve is parameterized for specific axes using machine data:
MD32000 $MA_MAX_AX_VELO (maximum axis velocity)
MD35220 $MA_ACCEL_REDUCTION_SPEED_POINT
(speed for reduced acceleration)
MD35230 $MA_ACCEL_REDUCTION_FACTOR (reduced acceleration)
MD32300 $MA_MAX_AX_ACCEL (Maximum axis acceleration)
MD35242 $MA_ACCEL_REDUCTION_TYPE
(type of acceleration reduction: 0 = constant, 1 = hyperbolic, 2 = linear)
