Set point input calibration
햲
Apply the input voltage of 0% set point setting (e.g. 0 V) across terminals 2-5.
햳
Enter in C2 (Pr. 902) the frequency which should be output by the inverter at the deviation of 0%
(e.g. 0 Hz).
햴
In C3 (Pr. 902), set the voltage value at 0%.
햵
Apply the voltage of 100% set point (e.g. 5 V) to across terminals 2-5.
햶
Enter in Pr. 125 the frequency which should be output by the inverter at the deviation of 100%
(e.g. 50 Hz).
햷
In C4 (Pr. 903), set the voltage value at 100%.
Process value input calibration
햲
Apply the input current of 0% detector setting (e.g. 4 mA) across terminals 4-5.
햳
Make calibration of the process value bias (%) using C6 (Pr. 904).
햴
Apply the input current of 100% detector setting (e.g. 20 mA) across terminals 4-5.
햵
Make calibration of the process value gain (%) using C7 (Pr. 905).
NOTE The frequency set in C5 (Pr. 904) and Pr. 126 should be the same as set in C2 (Pr. 902) and Pr. 125.
