7.2.5.2 One-quadrant ramp (ramp type 1)
This function limits the input signal's rate of change to the defined <AccelerationTime> (0x6331).
This ramp type is active, if the parameter <Type> (0x6330) is set to 1.

7.2.5.2.1 Object 0x6331: Acceleration time
This parameter defines the output signal's maximum rate of change. The acceleration time corresponds to the
time the signal needs for a change from 0 to 100 % as shown in  Figure 59, page 141. The acceleration
time can be specified with a resolution of 1 s, 100 ms, 10 ms or 1 ms.
