Parameter Description
Parameter Description
•
Once the motor is automatically restarted, the output frequency of the inverter will be the target
frequency, but the output voltage will be zero. Then the voltage will be increased gradually to the
expected voltage value. The period for the voltage increase is called the restart voltage rising time
(P.58).
•
P.150 has four digits, and each digit has a distinct meaning. Their positions are presented as
following:
Note: 1. P.150 must be set when using the restart function,
2. When the value of P.150 is not 0, default linear acceleration/deceleration curve.
3. If the single digit of P.150 is 1, P.150 cannot write-in.
5.25 Input Signal Filter Constant (P.60)
P.60 “Input signal filter constant”
When the running frequency is set by a voltage signal or a current signal, the voltage/current signal
would be processed by an AD converter. Due to the effect of device accuracy or noises, the external
voltage signal or current signal may fluctuate and as a result, the running frequency fluctuates, too.
The input signal filter constant setting P.60 is used to filter the fluctuation of the running frequency
caused by the above factors. The larger the P.60 set value is, the better the filter performance is, but
a larger delay would be resulted in.
