<Set point input calibration>
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. 50Hz).
6. In C4 (Pr. 903), set the voltage value at 100%.
<Detector output calibration>
1. Apply the output current of 0% detector setting (e.g. 4mA) across terminals 4-5.
2. Make calibration using C6 (Pr. 904).
3. Apply the output current of 100% detector setting (e.g. 20mA) across terminals 4-5.
4. Make calibration using C7 (Pr. 905).
REMARKS
⋅ The frequency set in C5 (Pr. 904) and Pr. 126 should be the same as set in C2 (Pr. 902) and Pr. 125.
The results of the above calibration are as shown below:

CAUTION
⋅ If the multi-speed (RH, RM, RL signal) or jog operation (jog signal) is entered with the X14 signal on, PID control is stopped
and multi-speed or jog operation is started.
⋅ If the setting is as follows, PID control becomes invalid. Pr. 79 = "6" (switchover mode)
⋅ When the Pr. 128 setting is "20" or "21", note that the input across inverter terminals 1-5 is added to the set value across
terminals 2-5.
⋅ When Pr. 22 = "9999", the terminal 1 is used for stall prevention level input. Therefore, when using the terminal 1 for PID
control, set Pr. 22 to other than "9999".
⋅ Changing the terminal function using any of Pr. 178 to Pr. 189, Pr. 190 to Pr. 196 may affect the other functions. Please make
setting after confirming the function of each terminal.
⋅ The remote operation function is invalid during PID operation.
