Terminal AM adjustment

How to adjust the scale of the meter with the inverter run
As an example, this section describes how to adjust the scale of the frequency meter connected to the terminal [FM].
Use the adjustment screw of the meter to set a zero point in advance.
This method can apply to the meter connected to the terminal [AM] as well.
1 ) Connect the frequency meter
2) In the basic parameters of [Setting mode], set [FMSL: Terminal FM function] to "0: Output frequency".
The default setting of [FMSL] is "0".
3) In the basic parameters of [Setting mode], select [FM: Terminal FM adjustment] and press the [OK] key.
The output frequency of the inverter is displayed in the upper part of the screen, and the output level (%) of the terminal [FM] in the lower part.
4) Turning the touch wheel will change the indication of the meter and the output level (%) of the terminal.
[FM] in the lower field of the screen. Adjust the scale so that the indication of the meter matches the output frequency.
5) Press the [OK] key to complete the adjustment of the meter.

How to adjust the scale of the meter with the inverter stopped
You can adjust the scale of the meter even at the inverter stop state.
When [FMSL: Terminal FM adjustment] and [F670: Terminal AM adjustment] are set "22", signal value is fixed at the following values.

For 4 - 20 mA output
This is when [F682: Terminal FM inclination polarity] is "1: Positive inclination (upward slope)" and [F683: Terminal FM bias] is "0". When[F682] is set to "0: Negative inclination (downward slope)", the inclination becomes negative.
This is when [F682] is "1" and [F683: Terminal FM bias] is "20". 20% value (4mA) of the full scale output current (20 mA in this case) will be the output current at internal calculated value of 0%.
Adjust the values of [F682: Terminal FM inclination polarity] and [F683: Terminal FM bias] for 4 - 20 mA output.
