• Calibrating set point input
(Example: To enter the set point on terminal 2)
1.
1. Apply the input (for example, 0 V) of set point setting 0% across terminals 2 and 5.
2.
Using C2 (Pr.902), enter the frequency (for example, 0 Hz) to be output by the inverter when the deviation is 0%.
3.
Using C3 (Pr.902), set the voltage value at 0%.
4.
Apply the input (for example, 5 V) of set point setting 100% across terminals 2 and 5.
5.
Using Pr.125, enter the frequency (for example, 60 Hz) to be output by the inverter when the deviation is 100%.
6.
Using C4 (Pr.903), set the voltage value at 100%.
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 C6 (Pr.904).
3.
Apply the input (for example, 20 mA) of measured value 100% across terminals 4 and 5.
4.
Perform calibration by C7 (Pr.905).
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 display unit for analog input can be changed from "%" to "V" or "mA". (Refer to
• The following figure shows the results of having performed the calibration above.
