H4-01 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).
2 Multi Function Analo Output erminal FM Gain and Bias
Multi Function Analo Output erminal AM Gain and Bias
Parameters H4-02 and H4-05 set the terminal FM and AM output signal level when the value of the selected monitor is at
100%. Parameters 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 or -10 to +10 Vdc, or 4 to 20 mA using parameter H4-07 and
H4-08. illustrates how gain and bias settings work.

When viewing a gain setting parameter (H4-02 or H4-05) on the HOA keypad, the analog output will supply a voltage signal
equal to 100% of the monitor value (including changes made from bias and gain settings). When viewing a bias setting
parameter (H4-03 or H4-06), the analog output voltage will supply a signal equal to 0% monitor value.
Example 1: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.
Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.
