H4-02, H4-03: Multi-Function Analog Output Terminal FM Gain and Bias
■
H4-05, H4-06: Terminal AM Gain and Bias
Parameters H4-02 and H4-05 set the terminal FM and AM output signal level equal to 100% of the monitor (gain).
Parameters H4-03 and H4-06 set the bias added to the monitor output for terminals FM and AM. Both are set as a
percentage, where 100% equals 10 Vdc analog output. The output voltage of both terminals is limited to 10 Vdc.
Select an output signal range between 0 to +10 Vdc or -10 to +10 Vdc using parameters H4-07 and H4-08.

Using Gain and Bias to Adjust Output Signal Level
The output signal is adjustable while the drive is stopped.
Terminal FM
1.
View the value set to H4-02 (Terminal FM Monitor Gain) on the digital operator. A voltage equal to 100% of the
parameter being set in H4-01 will be output from terminal FM.
2.
Adjust H4-02 viewing the monitor connected to the terminal FM.
3.
View the value set to H4-03 on the digital operator, terminal FM will output a voltage equal to 0% of the parameter
being set in H4-01.
4.
Adjust H4-03 viewing the output signal on the terminal FM.
Terminal AM
1.
View the value set to H4-05 (Terminal AM Monitor Gain) on the digital operator. A voltage equal to 100% of the
parameter being set in H4-04 will be output from terminal AM.
2.
Adjust H4-05 viewing the monitor connected to the terminal AM.
3.
View the value set to H4-06 on the digital operator, terminal AM will output a voltage equal to 0% of the parameter
being set in H4-04.
4.
Adjust H4-06 viewing the output signal on the terminal AM.
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%.
