■ 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. Figure 5.32
illustrates how gain and bias settings work.
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%.
