3.5 Specifications of I/O Signals
3.5.1 Recognition of Input Signals
The input signals from this controller have an input time constant, in order to prevent malfunction caused by chattering,
noise, etc.
Each input signal will switch the applicable setting when received continuously for 6 msec or more.
In other words, when a given input is switched from OFF to ON, the controller will recognize the ON state of the signal
only after elapse of 6 msec.
The same applies to the switching of an input from ON to OFF. (Fig. 1)
