5.6 F: Option Settings210 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual■ F3-03: Digital Input Option DI-A3 Data Length SelectionDetermines the number of bits for the option card input that sets the frequency reference.Setting 0: 8 bitSetting 1: 12 bitSetting 2: 16 bit◆ F4: Analog Monitor Card SettingsThese parameters set up the drive for operation with the analog output option card AO-A3. This section describesparameters that govern operation with an analog output option card. Refer to the instruction manual packaged with theoption card for specific details on installation, wiring, input signal level selection, and parameter setup.■ F4-01, F4-03: Terminal V1, V2 Monitor SelectionSelects the data to output from analog terminal V1. Enter the final three digits of U- to determine which monitordata is output from the option card. Some monitors are only available in certain control modes.■ F4-02, F4-04, F4-05, F4-06: Terminal V1, V2 Monitor Gain and BiasParameters F4-02 and F4-04 determine the gain, while parameters F4-05 and F4-06 set the bias. These parameters are setas a percentage of the output signal from V1 and V2 where 100% equals 10 V output. The terminal output voltage islimited to 10 V.Using Gain and Bias to Adjust Output Signal LevelWhen viewing the values set to F4-02 or F4-05 on the digital operator, a voltage equal to 100% of the parameter beingviewed (including current gain and bias settings) will be output from terminal V1 or V2. When viewing the value set toF4-05 or F4-06, terminal V1 or V2 will output a voltage equal to 0% of the parameter being viewed (including currentgain and bias settings).Example 1: F4-02 = 0%, F4-02 = 80%. When the parameter setting display for F4-02 is accessed using the digitaloperator, terminal V1 will output a voltage of 8 V, even when the drive is stopped.Example 2: F4-03 = 5%. When the parameter setting display for F4-03 is accessed using the digital operator, terminal V1will output a voltage of 0.5 V, even when the drive is stopped.■ F4-07, F4-08: Terminal V1, V2 Signal LevelSets the output signal level for terminals V1 and V2.Setting 0: 0 to 10 VSetting 1: -10 to 10 VNo. Parameter Name Setting Range DefaultF3-03 Digital Input Option DI-A3 Data Length Selection 0 to 2 2No. Parameter Name Setting Range DefaultF4-01 Terminal V1 Monitor Selection 000 to 999 102F4-03 Terminal V2 Monitor Selection 000 to 999 103No. Parameter Name Setting Range DefaultF4-02 Terminal V1 Monitor Gain -999.9 to 999.9% 100.0%F4-04 Terminal V2 Monitor Gain -999.9 to 999.9% 50.0%F4-05 Terminal V1 Monitor Bias -999.9 to 999.9% 0.0%F4-06 Terminal V2 Monitor Bias -999.9 to 999.9% 0.0%No. Parameter Name Setting Range DefaultF4-07 Terminal V1 Signal Level 0, 1 0F4-08 Terminal V2 Signal Level 0, 1 0
