7.1.4.3 Group 3.3.4: Motor Potentiom
With a motor potentiometer function, 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 ac-
tive, 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)
The Motor potentiometer reset parameter (P3.3.4.4) is used to choose whether to reset (set to Min-
Freq) the Motor Potentiometer frequency reference when stopped or when powered down.
Motor potentiometer frequency reference is available in all control places in menu Group 3.3: Ref-
erences. The motor potentiometer reference can be changed only when the drive is in run state.
