5.
Using
Pr.125
6.
Using
C4 (Pr.903)
NOTE
• When the set point is set at Pr.133, the setting frequency of C2 (Pr.902) is equivalent to 0% and the setting frequency of Pr.125
(Pr.903) is equivalent to 100%.
• Measured value input calibration
1.
Apply the input (for example, 4 mA) of measured value 0% across terminals 4 and 5.
2.
Perform calibration by
3.
Apply the input (for example, 20 mA) of measured value 100% across terminals 4 and 5.
4.
Perform calibration by
NOTE
• Set the frequencies set at C5 (Pr.904) and Pr.126 to each of the same values set at C2 (Pr.902) and Pr.125.
• The following figure shows the results of having performed the calibration above.
