3.5.17 Output variation limiter (buffer memory address 44, 76: Un\G44, Un\G76)

3.5.18 Sensor compensation value setting (buffer memory address 45, 77: Un\G45,

(1) Sets the upper and lower limit values for actually outputting the manipulated
value (MV) calculated by PID operation to an external device.
(2) The setting range is -50 to 1050 (-5.0% to 105.0%).
Make setting so that the (lower output limiter value) is less than the (upper output
limiter value).
(3) The current value output, when output is off (PID control stop), depends on the
lower output limiter
Setting value

(1) This function controls a sudden change in the manipulated value.
Set the variation of the manipulated value per second.
Mainpulated value (MV)
Mainpulated value (MV)2
Mainpulated value (MV)1
(2) The setting range is 0 to 1000 (0.1 to 100.0%).
For example, when the output variation limiter is set to 10 (1.0%), the output
variation will be 1% per second at a sudden manipulated value change of 50%,
and it will take 50 seconds until the output value changes to 50% actually.
(3) Setting default value of 0 the output variation limiter function.
(1) Sets the compensation value used when there is a difference between the
measure temperature and the actual temperature due to measured temperature
conditions, etc. (Refer to Section 3.2.5.)
(2) Set the value within the range of -5000 to 5000 (-500.0 to 500.0
thermocouple input.
For micro voltage, voltage and current input, set -5000 to 5000 (-50.00 to 50.00
%) for full-scale of the set input range.
