3.4.22 CH[ ] input signal error detection setting value/CH[ ] Input signal error detection lower limit setting val-
(1) Set the input signal error detection upper limit value to less than 25mA.
If the setting is 25mA or more, the error may not be detected.
(2) If a value outside the setting range is set, an error occurs and an error code is
stored in the Error code (Un\G19). In this case, the operation is performed
based on the setting before the error detection.
(3) The following table lists the lower limit value, offset value, and gain value for
each input range.
