To calibrate the meters connected to terminals FM and AM, use these parameters:
-
H4-02 [Terminal FM Analog Output Gain]
-
H4-03 [Terminal FM Analog Output Bias]
-
H4-05 [Terminal AM Analog Output Gain]
-
H4-06 [Terminal AM Analog Output Bias]
Set these parameters where the output voltage of 10 V and output current of 20 mA are 100% of the signal level. Use jumper switch S5 and H4-07 [Terminal FM Signal Level Select] or H4-08 [Terminal AM Signal Level Select] to select the voltage output and current output.

Figure 1 and Figure 2 show the gain and bias.
Figure 1. Analog Output Gain/Bias Configuration Example 1
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:
-
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%.
-
Adjust H4-02 while referencing the meter scale connected to terminal FM.
-
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%.
-
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:
-
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%.
-
Adjust H4-05 while referencing the meter scale connected to terminal AM.
-
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%.
-
Adjust H4-06 while referencing the meter scale connected to terminal AM.
