3.5.24 MAN output setting (buffer memory address 51, 83: Un\G51, Un\G83)
(1) This area is used to set the manipulated value in the manual control mode.
(2) MAN output setting is valid for the manual control mode 1 and 2 only.
The changed setting value is not output in the normal control mode and the
program control mode even if the setting value has been changed, as the system
overwrites it with the manipulated value calculated in PID operations.
(3) The manual control modes 1 and 2 have different setting ranges and settings for
the MAN output setting.
Mode Setting range Settings
Manual mode1 -50 to 1050 (-5.0 to 105.0%) *1
Set the manipulated value for
manual control with %.
Manual mode2 0 to 4000 *2
Set the analog output for using the
simplified analog I/O function with
digital value.
*1: -50 to 0 is output as 3.2 to 4 mA, and 1000 to 1050 as 20 to 20.8 mA. Set the
value within -32768 to -51 to turn off the output. In this case, the output is near
0mA.
*2: Set the value within -32768 to -1 to turn off the output. In this case, the output is
near 0mA.
3.5.25 Setting change rate limiter (buffer memory address 52, 84: Un\G52, Un\G84)
(1) This setting is made to set the variation of the set value per minute to a set value
(SV) change. This will suppress a derivative kick (sudden change in the
manipulated value).

(2) For thermocouple input, set with temperature.
For micro voltage, voltage and current, set with % for full-scale.
The following shows the setting range.
