With a motor potentiometer, the user can increase and decrease the output frequency. By connect-
ing a digital input to parameter P3.3.4.1 (
output frequency will rise as long as the signal is active. The parameter P3.3.4.2 (
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
tion/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 ac-
tivated.
P3.3.4.4 M

The previous motor potentiometer frequency reference is kept past
the stop state and stored to memory in case of power down.
Motor potentiometer frequency reference is set to zero when the drive
is in stop state or the drive is powered down.
Motor potentiometer frequency reference is set to zero only in a
power down situation.
