7.2.5.3 Two-quadrant ramp (ramp type 2)
This function limits the input signal's rate of change to the defined <AccelerationTime> (0x6331) and
<DeccelerationTime> (0x6332).
This ramp type is active, if the parameter <Type> (0x6330) is set to 2.

7.2.5.3.1 Object 0x6331: Acceleration time
This parameter is the same as the acceleration time for ramp type 1.
Chapter "7.2.5.2.1 Object 0x6331: Acceleration time", page 141
7.2.5.3.2 Object 0x6334: Deceleration time
This parameter defines the output signal's maximum rate of change. The deceleration time corresponds to the
time that the signal needs for a change from 100 to 0 %. The deceleration time can be specified with a resolu-
tion of 1 s, 100 ms, 10 ms or 1 ms.
