u H4: Multi-Function Analog Outputs
These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive
performance.

H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection
Sets the desired drive monitor parameter U -
Monitors on page 414 for a list of all monitors. The "Analog Output Level" column indicates if a monitor can be used
for analog output.
Example: Enter "103" for U1-03.
No.

Multi-Function Analog Output Terminal FM Monitor Selection
H4-04
Multi-Function Analog Output Terminal AM Monitor Selection
A setting of 031 or 000 applies no drive monitor to the analog output. With this setting, terminal functions as well as FM
and AM output levels can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).

H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
H4-05, H4-06: Multi-Function Analog Output Terminal AM Gain and Bias
Parameter H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameter H4-03 and H4-06 set the terminal FM and AM output signal level when the value of the selected
monitor is at 0%. Both are set as a percentage, where 100% equals 10 Vdc or 20 mA analog output and 0% equals 0 V or
4 mA. The output voltage of both terminals is limited to +/-10 Vdc.
The output signal range can be selected between 0 to +10 Vdc, -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. Figure 5.74 illustrates how gain and bias settings work.

Using Gain and Bias to Adjust Output Signal Level
It is possible to calibrate the meter when the drive is stopped. Follow the procedure below.
Terminal FM
1.
Use the digital operator to display the monitor gain for terminal FM (H4-02). Make sure that the voltage output is
100% of the monitor level selection for terminal FM (H4-01).
2.
Adjust the setting to parameter H4-02 accordingly while watching the read out of the meter connected to terminal
FM.
3.
Use the digital operator to display the monitor bias for terminal FM (H4-03). Make sure that the voltage output is
0% of the monitor level selection for terminal FM (H4-01).
4.
Adjust the setting to parameter H4-03 accordingly while watching the read out of the meter connected to terminal
FM.
Terminal AM
1.
Use the digital operator to display the monitor gain for terminal AM (H4-05). Make sure that the voltage output is
100% of the monitor level selection for terminal AM (H4-04).
2.
Adjust the setting to parameter H4-05 accordingly while watching the read out of the meter connected to terminal
AM.
3.
Use the digital operator to display the monitor bias for terminal AM (H4-06). Make sure that the voltage output is
0% of the monitor level selection for terminal AM (H4-04).
4.
Adjust the setting to parameter H4-06 accordingly while watching the read out of the meter connected to terminal
AM.
Example 1: To have an output signal of 5 V at terminal FM when the monitored value is at 100%, set H4-02 to 50%.
