PID control (Pr. 128 to Pr. 134)
(8) Calibration example
<Set point input calibration>
1. Apply the input voltage of 0% set point setting (e.g. 0V) to across terminals 2-5.
2. Make calibration using Pr. 902. At this time, enter the speed output by the inverter at the deviation of 0% (e.g. 0r/
min).
3. Apply the voltage of 100% set point setting (e.g. 10V) to across terminals 2-5.
4. Make calibration using Pr. 903. At this time, enter the speed output by the inverter at the deviation of 100% (e.g.
1800r/min).
<Detector output calibration>
1. Apply the output current of 0% detector setting (e.g. 0V) to across terminals 1-5.
2. Make calibration using Pr. 917.
3. Apply the output current of 100% detector setting (e.g. 5V) to across terminals 1-5.
4. Make calibration using Pr. 918.
CAUTION
The frequencies set in Pr. 917 and Pr. 918 should be the same as set in Pr. 902 and Pr. 903.
The results of the above calibration are as shown below:

CAUTION
1. 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.
2. When "6" (switchover mode) is selected for Pr. 79, PID is made invalid.
3. When "1" (online auto tuning) is selected for Pr. 95, PID control is made invalid.
4. Changing the terminal function using any of Pr. 180 to 183 and Pr. 187 and Pr. 190 to 192 and Pr. 195
may affect the other functions. Confirm the functions of the corresponding terminals before making
setting.
5. When PID control is selected, the minimum speed is as set in Pr. 902 and the maximum speed is as
set in Pr. 903.
(Pr. 1 "maximum speed" and Pr. 2 "minimum speed" settings are also valid.)
