Special operation and frequency control
<Set point input calibration>
1) Setting with terminal 2 input
1. Apply the input voltage of 0% set point setting (e.g. 0V) across terminals 2-5.
2. Enter in C2 (Pr. 902) the frequency which should be output by the inverter at the deviation of 0% (e.g. 0Hz).
3. In C3 (Pr. 902), set the voltage value at 0%.
4. Apply the voltage of 100% set point (e.g. 5V) to across terminals 2-5.
5. Enter in Pr. 125 the frequency which should be output by the inverter at the deviation of 100% (e.g. 60Hz).
6. In C4 (Pr. 903), set the voltage value at 100%.
2) 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%.
<Measured value calibration>
1) When both or one of C42 (Pr.934) and C44 (Pr.935) is "9999".
1. Apply the input current of 0% measured value (e.g. 4mA) across terminals 4-5.
2. Make calibration using C6 (Pr. 904).
3. Apply the input current of 100% measured value (e.g. 20mA) across terminals 4-5.
4. Make calibration using C7 (Pr. 905).
2) When both of C42 (Pr.934) and C44 (Pr.935) ≠ "9999".
1. Apply the input current of 0% measured value (e.g. 4mA) across terminals 4 and 5.
2. Set PID display value at 0% measured value (example: 15(°C)) to C42 (Pr.934) , and calibrate C43 (Pr.934).
3. Apply the input current of 100% measured value (e.g. 20mA) across terminals 4 and 5.
4. Set PID display value at 100% measured value (example: 35(°C)) to C44 (Pr.935), and calibrate C45 (Pr.935).
REMARKS
⋅ The frequency set in C5 (Pr. 904) and Pr. 126 should be the same as set in C2 (Pr. 902) and Pr. 125.
