CV3100 series and MINI series high performance general purpose inverter instruction manual
inverter output due to the instability of analog signal. The lag function of this
parameter is used to avoid fluctuation around zero frequency.
Taken example to analog input channel AI1 as below:
Diagram 6-32 Zero frequencyhysteresis running
If the running command is given and the above parameters (PA.00、PA.01) are not be
set, the frequency output will be rigidly according to the relationship between analog
voltage and frequency. When the factory setting value of PA.00 and PA.01 are changed,
the inverter will not start to run if the AI1 input frequency value is less than the
summation by PA.00 and PA0.01; if the it is equal to or exceeds the summation by
PA.00 and PA.01, can the motor start to run and accelerate to the frequency
corresponding to AI1 input according to preset acceleration time.
During decelerating, when the frequency output reaches the summation by
PA.00+PA0.01, the inverter will not stop running, only when the frequency
corresponding to AI1 input reaches or be lower than PA.00, it can stop running.
This function can be used to realize the sleeping function of inverter as well as energy
saving operating.
