CH1 Input signal error detection setting value/lower limit set value [Q compatible mode]
In the Q compatible mode, set a value to detect an error for the input analog value.
The operation varies depending on the value set in 'CH1 Input signal error detection extension/input signal error detection
setting' (Un\G47).
■Buffer memory address
The following shows the buffer memory address of this area.
Only the R60AD8-G can use this area.
Buffer memory name
CH Input signal error detection setting value/CH
Input signal error detection lower limit set value (in Q
compatible mode)
■Setting range
The setting range is from 0 to 250 (0 to 25.0%). Set it in a unit of 1 (0.1%).
For example, set 150 in the buffer memory area to set 15%.
In the channel where a value out of the range is set, an input signal error detection setting value range error (error code:
1C1H) occurs.
• When 'CH1 Input signal error detection extension/input signal error detection setting' (Un\G47) is set to Upper limit value/
lower limit value same (0).
The area is used to set the input signal error detection setting value.
The input signal error detection upper limit value and the input signal error detection lower limit value are calculated as
follows: The calculated values vary depending on the input range used.
Input signal error detection upper limit value =
Gain value of each range + (Gain value of each range - Offset value of each range) × (Input signal error detection set value
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 set value
*1 The input signal error detection setting value is set in this area.
• When 'CH1 Input signal error detection extension/input signal error detection setting' (Un\G47) is set to Upper limit value/
lower limit value different (1)
The area is used to set the input signal error detection lower limit set value.
Setting 251 disables the input signal error detection.
The input signal error detection upper limit value and the input signal error detection lower limit value are calculated as
follows: The calculated values vary depending on the input range used.
Input signal error detection upper limit value =
Gain value of each range + (Gain value of each range - Offset value of each range) × (Upper limit set value
Input signal error detection lower limit value =
Lower limit value of each range - (Gain value of each range - Offset value of each range) × (Lower limit set value
*1 The upper limit set value is the value set in 'CH1 Input signal error detection upper limit set value' (Un\G150).
*2 The lower limit set value is the value set in this area.
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9).
■Default value
The default value is 50 for all channels.
