SPECIFICATIONS
3.4.13 Input signal error detection flag (Un\G49)
(1) If the analog input value detected falls outside the setting range sets to the CH input
signal error detection setting value/CH Input signal error detection lower limit setting
value (Un\G142 to Un\G149), or CH input signal error detection upper limit setting
value (Un\G150 to Un\G157), the Input signal error detection flag for the
corresponding channel turns to 1.
(2) By bringing the analog input value within the setting range and turning ON the Error
clear request (YF), the Input signal error detection flag turns OFF.
(3) If an error is detected on any one of the channels for which input signal error detection
is enabled, the Input signal error detection signal (XC) also turns ON.
(4) When the operating condition setting request (Y9) is turned ON, the Input signal error
detection flag is cleared.
