4. Operation Using I/O Signals
4.1.4 Recognition of Input Signals
The input signals of this controller have an input time constant to prevent malfunction due to chattering, noise, etc.
Each input signal is switched when the new signal state has continued for at least 6 msec.
In other words, when the input is switched from OFF to ON, the controller will recognize that the input signal is ON after
6 msec. The same applies when the input is switched from ON to OFF.
* Excluding command pulse input (PP•/PP, NP•/NP).
