4. Parameter description
Parameter
Note: 1. When need restart function, P.150 must be set.
2. When the value of P.150 is not 0, default linear acceleration/deceleration curve.
3. The detection of rotation of P.150 is only to immediate frequency search.
4. This function is valid in V/F curve. It means P.300 must be set to 0.
4.26 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 A/D converter. Due to the effect of device accuracy or noises, the
external voltage signal or current signal may fluctuate and thus the running frequency fluctuates.
● 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, but larger delay is resulted in.

● If the operation box is located away from the control box, you can use contact signals to perform
continuous variable-speed operation, without using analog signals, when in ‘external mode’,
‘combined mode 1’ or ‘combined mode 5’.
