P3.3.4.1 MOTOR POTENTIOMETER UP (ID 418)
With a motor potentiometer, you can increase and decrease the output frequency. When you
connect a digital input to parameter Motor Potentiometer UP, and have the digital input
signal active, the output frequency rises.
P3.3.4.2 MOTOR POTENTIOMETER DOWN (ID 417)
With a motor potentiometer, you can increase and decrease the output frequency. When you
connect a digital input to parameter Motor Potentiometer DOWN, and have the digital input
signal active, the output frequency falls.
3 different parameters have an effect on how the output frequency rises or falls when Motor
Potentiometer UP or DOWN is active. These parameters are Motor Potentiometer Ramp
Time (P3.3.4.3), Ramp Acceleration Time (P3.4.1.2), and Ramp Deceleration Time (P3.4.1.3).

P3.3.4.4 MOTOR POTENTIOMETER RESET (ID 367)
This parameter defines the logic for the resetting of the frequency reference of the motor
potentiometer.
There are 3 selections in the reset function: no reset, reset when the drive stops, or reset
when the drive is powered down.
