Analogue input AI2 filtering time
When select AI1 and AI2 inputs as open-loop frequency setting source, the relationship between the
analogue input and the setting frequency is shown as figure:
The analogue voltage reasults from setting frequency signal disposed by analogue input filtering, bias
and gain. The relationship between the analogue voltage and the setting frequency is set by
parameters of Group F05.
• The formula is: Y=kX+b
• Y is actual output value, X is output value with ratio and gain not being adjusted, k is analogue
input gain (F16.06, F16.09), b is analogue input bias (F16.05, F16.08).
• F16.07 and F16.10 define the filtering constant time. It is used to filter the analogue signal.The
bigger the constant, the higher the immunity level, but the response time is prolonged with the
increase of this constant. That is, the smaller the constant, the shorter the response time, but the
lower the immunity level.

Maximum input pulse frequency
When set the DI6 terminal as pulse input, F16.17 defines the maximum input pulse frequency.
Input pulse filtering time
It is used to filter the input pulse frequency and filter out the small fluctuations in the pulse frequency.
