H4: Multi-Function Analog Outputs

These parameters assign functions to analog output terminals FM and AM for monitoring a specific aspect of drive
performance.
n H4-01, H4-04: Multi-Function Analog Output Terminal FM, AM Monitor Selection
Sets the desired drive monitor parameter Uo-oo to output as an analog value via terminal FM and AM.
Parameters on page 171 for a list of all monitors. The "Analog Output Level" column indicates whether a monitor can be
used for analog output.
Example: Enter "103" for U1-03.
No.
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 either of these settings, the output level of the
terminals FM and AM can be set by a PLC via a communication option or MEMOBUS/Modbus (through mode).
n 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
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 analog output and 0% equals 0 V. 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 using parameter H4-07 and H4-08.
1.80 illustrates how gain and bias settings work.
No.
H4-02 Multi-Function Analog Output Terminal FM Gain
H4-03 Multi-Function Analog Output Terminal FM Bias
H4-05 Multi-Function Analog Output Terminal AM Gain
H4-06 Multi-Function Analog Output Terminal AM Bias
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.
