■Conditions to execute/not to execute the temperature judgment
The following table lists the conditions used to determine whether to execute the temperature judgment.
Executed: , Not executed: 
'Setting/operation mode 'PID continuation flag'
*1
command' (Y1) (Un\G306)
Setting mode at power-ON Stop (0), Continue (1)
Operation mode (during Stop (0), Continue (1)
operation)
Setting mode (after Stop (0)
operation)
Continue (1)
*1 For each timing, refer to the following:
Page 164 Setting/operation mode command
When 'CH1 Unused channel setting' (Un\G502) has been set to Unused (1), the temperature judgment is not executed even
though the above conditions have been satisfied. ( Page 259 CH1 Unused channel setting)
CH1 Temperature process value (PV)
A detected temperature value to which the sensor correction has been executed is stored in this area.
The value to be stored differs depending on the value stored in 'CH1 Decimal point position' (Un\G400). ( Page 229 CH1
Decimal point position)
• When 'CH1 Decimal point position' (Un\G400) is No decimal point (0): A detected temperature value is stored as it is.
• When 'CH1 Decimal point position' (Un\G400) is First decimal place (1): A detected temperature value is stored after being
multiplied by 10.
When a value measured by a temperature sensor has exceeded the temperature measuring range, the
following value is stored:
• When the measured value is larger than the upper limit value of the temperature measuring range: Input
range upper limit value + 5% of full scale
• When the measured value is smaller than the lower limit value of the temperature measuring range: Input
range lower limit value - 5% of full scale
