Figure 12.22 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 to be output to terminal AM,
set
H4-03 [AM Analog Output Bias] = 30% .

Calibrate Terminal AM
Stop the drive to calibrate meters. Use this procedure to calibrate:
1. Show H4-02 [Terminal AM Analog Output Gain] on the keypad.
Terminal AM outputs the analog signal when the monitor item that you set in H4-01 [Terminal AM Analog
Output Select] is 100%.
2. Adjust H4-02 while referencing the meter scale connected to terminal AM.
3. Show H4-03 [Terminal AM 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 AM.
4. Adjust H4-03 while referencing the meter scale connected to terminal AM.

H4-01: Terminal AM Analog Output Select
Set the x-xx part of the Ux-xx [Monitor] . For example, set H4-01 = 102 to monitor U1-02 [Output Frequency] .
Note:
• You cannot use all of the monitors in all of the control methods.

Terminal AM Analog
Output Gain
Sets the gain of the monitor signal that is sent from MFAO terminal AM.
100.0%
(-999.9 - +999.9%)
The analog signal output from the AM terminal is a maximum of 10 V (or 20 mA). Use H4-07 [Terminal AM
Signal Level Select] to set the signal level.
