5-2-6 Signal filtering
L038 parameter set the input signal PULS and SIGN digital filter, the bigger number, the
longer filtering time constant .Range of the default value, the maximum pulse input frequency is
500kHz
（
kpps
）
, the number larger, the numerical input pulse frequency will be reduced.
Used for filtering of signal noise to avoid counting errors. If the phenomenon of working are
not accurate turn up result from the counts are not accurate, may increasing the parameter value.
5-2-7 Smoothing filtering
As the
diagram show, L040 parameter for instruction pulse proceed smooth filtering, with
exponential form of accelerated and deceleration. Filter will not lost input pulses, but will appear
instructions delay phenomenon. When it set as 0, the filter won’t work. Parameters means the time
which rises form 0 frequency to 63.2% of the position
command
frequency cost.
