The following diagram illustrates the gain and bias.
Figure 11.80 Analog Output Gain/Bias Setting Example 1
For example, when the parameter value set to analog output is 0 and a 3 V signal is output to terminal FM,
H3-04
[Terminal FM Analog Output Bias]
is set to 30%.
Figure 11.81 Analog Output Gain/Bias Setting Example 2
Calibrate Terminal FM
The output signal is adjustable while the drive is stopped. Use the following procedure to perform calibration.
1. Show
H4-02 [Terminal FM Analog Output Gain]
on the keypad.
The analog signal at the time when the monitor item selected with
H4-01 [Terminal FM Analog Output
Select]
is 100% is output from terminal FM.
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.
The analog signal at the time when the monitor item selected with
H4-01
is 0% is output from terminal FM.
4. Adjust
H4-03
while referencing the meter scale connected to terminal FM.
