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.
