■Precautions on parameter setting
• The logic switching parameters are validated when the PLC READY signal [Y0] is turned OFF to ON. (The logic is negative
right after power-on.)
• If the logic of each signal is set erroneously, the operation may not be carried out correctly. Before setting, check the
specifications of the equipment to be used.
Input filter setting method for external input signals
The input filter is used to suppress chattering when the external input signal is chattering by noise, etc.
The setting area of the input filter varies by the input type of "[Pr.116] FLS signal selection" to "[Pr.119] STOP signal selection".
■External input signals from the external device connected with the Simple Motion module
(upper/lower stroke limit signal (FLS/RLS), near-point dog signal (DOG), stop signal (STOP),
and external command signal/switching signal (DI))
Use the following parameter to set the input filter of the external input signals from the external device connected with the
Simple Motion module (upper/lower stroke limit signal (FLS/RLS), near-point dog signal (DOG), stop signal (STOP), and
external command signal/switching signal (DI)).
• "[Pr.153] External input signal digital filter setting" is not a parameter for each axis.
• "[Pr.153] External input signal digital filter setting" becomes valid when the power supply is turned ON, the CPU module is
reset, or the PLC READY signal [Y0] is turned ON.
• When lengthening the filter setting time, the signal detection timing will be slow.
• When "[Pr.153] External input signal digital filter setting" is set with a value other than "0 to 6", note that the module may
cause a failure.
