1ms
Note: It is
assumed that
the number of
anti-shake
waves is “2” by
default.
Fig. 7-13 Schematic Diagram of Terminal Filter Sampling
Since the multi-function input terminal is triggered by level or pulse, digital filtering is
needed when the terminal status is read, in order to avoid interference.
★
The parameters of this code do not need to be adjusted under normal circumstances.
Where adjustment is required, pay attention to the relationship between the filtering
time and terminal action duration, to avoid the susceptibility to interference due to
insufficient filtering times or slow responses and command losses arising from
excessive filtering times.
