Set point input calibration
Apply the input voltage of 0% set point setting (e.g. 0V) across terminals 2-5.
Enter in C2 (Pr. 902) the frequency which should be output by the inverter at the deviation
of 0% (e.g. 0Hz).
In C3 (Pr. 902), set the voltage value at 0%.
Apply the voltage of 100% set point (e.g. 5V) to across terminals 2-5.
Enter in Pr. 125 the frequency which should be output by the inverter at the deviation of
100% (e.g. 50Hz).
In C4 (Pr. 903), set the voltage value at 100%.
Process value input calibration
Apply the output current of 0% detector setting (e.g. 4mA) across terminals 4-5.
Make calibration of the process value bias (%) using C6 (Pr. 904).
Apply the output current of 100% detector setting (e.g. 20mA) across terminals 4-5.
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.
