■Setting range
• In the R mode
0 to the full scale of the input range (())
• In the Q compatible mode
0 to 10000 (0.0% to 1000.0%)
Ex.
In the Q compatible mode, when the following values have been set in the buffer memory areas, the proportional band (P)
becomes 60.
• 'CH1 Input range' (in the Q compatible mode) (Un\G32): 38 (Temperature measuring range: -200.0 to 400.0)
• 'CH1 Proportional band (P) setting' (in the Q compatible mode) (Un\G35): 100 (10.0%)
(Full scale)  (Proportional band (P) setting) = (400.0 - (-200.0))  0.1 = 60
■Two-position control
Set the proportional band (P) to 0.
For details on the two-position control, refer to the following:
Page 18 Control Method
■Default value
• In the R mode
For the R60TCTRT2TT2 and the R60TCTRT2TT2BW, the default value is 30 (30).
For the R60TCRT4 and the R60TCRT4BW, the default value is 30 (3.0).
• In the Q compatible mode
The default value is 30 (3.0%).
When the proportional band (P) has been set to 0, the auto tuning cannot be executed.
To execute the auto tuning, set the proportional band (P) to a value other than 0.
For details on the auto tuning function, refer to the following:
