P3)
Remote control place frequency reference selection
It defines the selected frequency reference source when the drive is remote
control. A second reference source is programmable in par. 3.12.

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).

Motor potentiometer ramp
Motor potentiometer reset
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.
0 = No Reset
1 = Reset if stopped
2 = Reset if powered down
P5.12 and P5.13 sets which digital inputs increase and decrease the motor
potentiometers reference.
