Value "1" selected for parameter:
According to how many of the inputs assigned for
Preset frequency selections are active, you can apply
the Preset frequencies 1 to 3.

P3.3.3.11 Preset Freq Sel1
P3.3.3.12 Preset Freq Sel2
Connect a digital input to these functions (see chapter
Group 3.1: Motor settings) to be able to apply Preset
frequencies 1 to 7.
8.2.6 Motor Potentiometer
P3.3.4.1 MotPot UP
P3.3.4.2 MotPot DOWN
With a motor potentiometer, the user can increase
and decrease the output frequency. By connecting a
digital input to parameter P3.3.4.1 (MotPot UP) and
having the digital input signal active, the output
frequency will rise as long as the signal is active. The
parameter P3.3.4.2 (MotPot DOWN) works vice
versa, decreasing the output frequency.
The rate how the output frequency either rises or falls
when Motor Potentiometer Up or Down is activated is
determined by the Motor potentiometer ramp time
(P3.3.4.3) and the Ramp acceleration/deceleration
times (P3.4.1.2/P3.4.1.3).
The Motor potentiometer reset parameter (P3.3.4.4)
will set the frequency reference to zero if activated.
P3.3.4.4 MotPot Reset
Defines the logic for resetting the motor potentiometer
frequency reference.
Selection
number
Selection name Note
0 No reset
The previous motor potentiometer frequency reference is kept past
the stop state and stored to memory in case of power down.
1 Stop state
Motor potentiometer frequency reference is set to zero when the
drive is in stop state or the drive is powered down.
2 Powered down
Motor potentiometer frequency reference is set to zero only in a
power down situation.
