Figure 2.90 Analog Output Gain/Bias Configuration Example 2
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.

Sets the monitoring number to be output from the MFAO terminal AM.
102
(000 - 999)
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.
• When you use the terminal in through mode, set this parameter to 000 or 031. You can set the terminal AM output level from the PLC
through MEMOBUS/Modbus communications or the communication option.
