Yaskawa iQpump1000 AC Drive Quick Start - Manual (Page 221)

Setting 3: 0 to 20 mA
The input level is 0 to 20 mA. Negative input values by negative bias or gain settings will be limited to 0%.
n H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.
No. Name Setting Range Default
H3-10 Terminal A2 Function Selection 0 to 32 B
n H3-11, H3-12: Terminal A2 Gain and Bias Setting
Parameter H3-11 sets the level of the input value selected that is equal to 10 Vdc input or 20 mA input to terminal A2.
Parameter H3-12 sets the level of the input value selected that is equal to 0 V, 4 mA or 0 mA input at terminal A2.
Use both parameters to adjust the characteristics of the analog input signal to terminal A2. The setting works in the same way
as parameters H3-03 and H3-04 for analog input A1.
No. Name Setting Range Default
H3-11 Terminal A2 Gain Setting -999.9 to 999.9% 100.0%
H3-12 Terminal A2 Bias Setting -999.9 to 999.9% 0.0%
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. Refer to U1:
Operation Status Monitors on page 401 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. Name Setting Range Default
H4-01 Multi-Function Analog Output Terminal FM Monitor Selection 000 to 999 102
H4-04 Multi-Function Analog Output Terminal AM Monitor Selection 000 to 999 103
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 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. Figure 4.39 illustrates how gain and bias settings work.
No. Name Setting Range Default
H4-02 Multi-Function Analog Output Terminal FM Gain -999.9 to 999.9% 100.0%
H4-03 Multi-Function Analog Output Terminal FM Bias -999.9 to 999.9% 0.0%
H4-05 Multi-Function Analog Output Terminal AM Gain -999.9 to 999.9% 50.0%
H4-06 Multi-Function Analog Output Terminal AM Bias -999.9 to 999.9% 0.0%
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.
