<Set point input calibration>
1. Apply the input voltage of 0% set point setting (e.g. 0V) across terminals 2-5.
2. Make calibration using the calibration parameters C2, C3. At this time, enter in C2
the frequency which should be output by the inverter at the deviation of 0% (e.g.
0Hz). (When using the FR-PU04, make calibration with Pr. 902.)
3. Apply the voltage of 100% set point (e.g. 5V) to across terminals 2-5.
4. Make calibration using Pr. 38 and calibration parameter C4. At this time, enter in Pr.
38 the frequency which should be output by the inverter at the deviation of 100%
(e.g. 60Hz). (When using the FR-PU04, make calibration with Pr. 903.)
<Detector output calibration>
1. Apply the output current of 0% detector setting (e.g. 4mA) across terminals 4-5.
2. Make calibration using the calibration parameter C6. (When using the FR-PU04,
make calibration with Pr. 904.)
3. Apply the output current of 100% detector setting (e.g. 20mA) across terminals 4-5.
4. Make calibration using the calibration parameter C7. (When using the FR-PU04,
make calibration with Pr. 905.)
Note: The frequencies set in the calibration parameter C5 and Pr. 39 should be equal
to those set in the calibration parameter C2 and Pr. 38, respectively.
