Preset speeds 0 - 7
Preset speed 0 is used as frequency reference when P3.3 = 1.
Preset speeds 1 - 7 can be used to determine frequency references that are
applied when appropriate combinations of digital inputs are activated. Pre-
set speeds can be activated from digital inputs despite of the active control
place.
Parameter values are automatically limited between the minimum and max-
imum frequencies. (Par. 3.1 and 3.2).

P3.13 is the speed variation ramp when motor potentiometer reference is
increased or decreased.
P3.14 tells under which circumstances the potentiometers reference should
be reset and start over from 0 Hz.
P5.12 and P5.13 sets which digital inputs increase and decrease the motor
potentiometers reference.
