Automatic setting at input range change
When the setting of 'CH1 Input range' (Un\G501) was changed, this function automatically changes data in the related buffer
memory areas to prevent the occurrence of a set value discrepancy error (error code: 1950H).
• 0: Disable
• 1: Enable
When Enable (1) has been set, the following buffer memory areas are automatically set or initialized when the setting of 'CH1
Input range' (Un\G501) is changed.
Buffer memory area name
CH1 Set value (SV) setting
CH1 Proportional band (P) setting
CH1 Alert set value 1 to CH1 Alert set value 4
CH1 Cooling proportional band (Pc) setting
CH1 Upper limit setting limiter
CH1 Lower limit setting limiter
Setting variation rate limiter/setting variation rate limiter (temperature rise)
CH1 Setting variation rate limiter (temperature drop)
CH1 Adjustment sensitivity (dead band) setting
CH1 Overlap/dead band setting
CH1 Alert dead band setting
CH1 Loop disconnection detection dead band
CH1 AT bias
CH1 Simultaneous temperature rise gradient data
CH1 Simultaneous temperature rise dead time
CH1 Disturbance judgment position
CH1 Sensor correction value setting
CH1 Sensor two-point correction offset value (measured value)
CH1 Sensor two-point correction offset value (corrected value)
CH1 Sensor two-point correction gain value (measured value)
CH1 Sensor two-point correction gain value (corrected value)

■Default value
The default value is Disable (0).
Setting variation rate limiter setting selection
When setting the variation amount of the set value (SV), select whether to set the variation amount limiter setting values in a
batch or individually at the temperature rise or temperature drop.
• 0: Set in a batch at temperature rise/temperature drop
• 1: Individually set at temperature rise/temperature drop
