■Enabling the setting
Turn offonoff 'Operating condition setting request' (Un\G70, b9) to enable the setting.
■Default value
The default value is Disable (0) for all the channels.
CH1 Input signal error detection lower limit setting value
Set a value to detect an error for the input analog value.
For details on the input signal error detection function, refer to the following.
Page 53 Input signal error detection function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Input signal error detection lower limit
setting value
CH Input signal error detection lower limit
setting value (In FX3 allocation mode function)
■Setting range
The possible setting range is from 0 to 250 (0 to 25.0%). Set it in a unit of 1 (0.1%).
In the channel where a value out of the above setting range is set, an input signal error detection setting value range error
(error code: 1C1H) occurs.
The input signal error detection lower limit value is calculated by using the input signal error detection lower limit set value as
the reference as follows. The input signal error detection lower limit value to be calculated varies depending on the input
range used.
• Input signal error detection lower limit value = Lower limit value of each range - (Gain value of each range - Offset value of
each range)  (Input signal error detection lower limit setting value/1000)
Detection conditions vary depending on 'CH1 Input signal error detection setting' (Un\G528) as follows:
• When Input signal error detection setting is set to Upper and lower limit detection (1), the detection is performed with both
the input signal error detection upper limit value and input signal error detection lower limit value.
• When Input signal error detection setting is set to Lower limit detection (2), the detection is performed only with the input
signal error detection lower limit value.
• When 'Input signal error detection setting' is set to Upper limit detection (3), the value set in this area is ignored.
• When Input signal error detection setting is set to Simple disconnection detection (4), the value set in this area is ignored.
■Enabling the setting
Turn offonoff 'Operating condition setting request' (Un\G70, b9) to enable the setting.
■Default value
The default value is 50 for all channels. When the FX3 allocation mode function is used, 20 is set for all channels.
