◆ H4: Analog Outputs
H4 parameters set the drive analog monitors. These parameters select monitor parameters, adjust gain and bias,
and select output signal levels.
■ Calibrate Meters Connected to MFAO Terminals FM and AM
You can use H4-02, H4-03, H4-05, and H4-06 [FM/AM Analog Output Gain/Bias] to calibrate meters connected
to terminals FM and AM.
No. Name Setting Range Default Setting
H4-02 Terminal FM Analog Output Gain -999.9 - 999.9% 100.0%
H4-03 Terminal FM Analog Output Bias -999.9 - 999.9% 0.0%
H4-05 Terminal AM Analog Output Gain -999.9 - 999.9% 50.0%
H4-06 Terminal AM Analog Output Bias -999.9 - 999.9% 0.0%
H4-07 Terminal FM Signal Level Select

Figure 11.114 shows the gain and bias.
Figure 11.114 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
[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 [FM Analog Output Gain] on the keypad.
