For example, when the parameter value set to analog output is 0, and a 3 V signal is output to terminal FM, H4-03
[Terminal FM Analog Output Bias] is set to 30%.
Calibrate Terminal FM
Stop the drive to calibrate meters. Use this procedure to calibrate:
1. Show H4-02 [Terminal FM Analog Output Gain] on the keypad.
Terminal FM outputs the analog signal when the monitor item that you set in H4-01 [Terminal FM Analog Output
Select] is 100%.
2. Adjust H4-02 while referencing the meter scale connected to terminal FM.
3. Show H4-03 [Terminal FM Analog Output Bias] on the keypad.
Terminal FM outputs the analog signal when the monitor item that you set in H4-01 is 0%.
4. Adjust H4-03 while referencing the meter scale connected to terminal FM.
Calibrate Terminal AM
Stop the drive to calibrate meters. Use this procedure to calibrate:
1. Show H4-05 [Terminal AM Analog Output Gain] on the keypad.
Terminal AM outputs the analog signal when the monitor item that you set in H4-04 [Terminal AM Analog
Output Select] is 100%.
2. Adjust H4-05 while referencing the meter scale connected to terminal AM.
3. Show H4-06 [Terminal AM Analog Output Bias] on the keypad.
Terminal AM outputs the analog signal when the monitor item that you set in H4-04 is 0%.
4. Adjust H4-06 while referencing the meter scale connected to terminal AM.
