6.1.4.3 Group 3.3.4: Motor Potentiom
With a motor potentiometer function, the user can increase and decrease the output frequen-
cy. 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)
The Motor potentiometer reset parameter (P3.3.4.4) is used to choose whether to reset (set to
MinFreq) 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:
References. The motor potentiometer reference can be changed only when the drive is in run
state.
