Set point input calibration
● Setting with terminal 2 input
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%.
● Setting with Pr. 133
When both or one of C42 (Pr. 934) and C44 (Pr. 935) is "9999".
For the set point, set a % converted value in the range of 0 to 100%.
When both of C42 (Pr. 934) and C44 (Pr. 935) ≠ "9999".
For the set point, set PID coefficient, which corresponds with 0 to 100%.
Process value input calibration
● When both or one of C42 (Pr. 934) and C44 (Pr. 935) is "9999"
Apply the input 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 input current of 100% detector setting (e.g. 20mA) across terminals 4-5.
Make calibration of the process value gain (%) using C7 (Pr. 905).
● When both of C42 (Pr. 934) and C44 (Pr. 935) ≠ "9999"
Apply the input current of 0% measured value (e.g. 4mA) across terminals 4 and 5.
Set PID display value at 0% measured value (example: 15(°C)) to C42 (Pr. 934), and
calibrate C43 (Pr. 934).
Apply the input current of 100% measured value (e.g. 20mA) across terminals 4 and 5.
Set PID display value at 100% measured value (example: 35(°C)) to C44 (Pr. 935), and
calibrate C45 (Pr. 935).
NOTE
The frequency set in C5 (Pr. 904) and Pr. 126 should be the same as set in C2 (Pr. 902) and
Pr. 125.
