5.7 H: Terminal Functions234 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual■ H2-06: Watt Hour Output Unit SelectionWhen one of the multi-function terminals is set to output the number of watt hours (H2-01, H2-02, or H2-03 = 39),parameter H2-06 determines the units for the output signal.This output function provides a watt hour meter or a PLC input by a 200 ms pulse signal. H2-06 determines thefrequency that pulses are issued to keep track of the kWh for the drive.Note: 1. A negative power output (i.e., regeneration) does not subtract from the total watt hours.2. The drive keeps track of the watt hours as long as the control circuit has power. The value is reset when the power supply is shut off.Figure 5.77Figure 5.77 Watt Hour Output Example◆ H3: Multi-Function Analog InputsThe drive is equipped with three multi-function analog input terminals: A1, A2, and A3. See Table 5.39 for a listing ofthe functions that can be set to these terminals.■ H3-01: Terminal A1 Signal Level SelectionSelects the input signal level for analog input A1.Setting 0: 0 to 10 VdcThe input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain andbias settings will be simply read as 0%.Setting 1: –10 to 10 VdcThe input level is –10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, thenthe motor will rotate in reverse.■ H3-02: Terminal A1 Function SelectionDetermines the function assigned to analog input terminal A1. Refer to Multi-Function Analog Input Terminal Settingson page 237 for instructions on how to adjust the signal level.■ H3-03, H3-04: Terminal A1 Gain and Bias SettingsParameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (gain).Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1 (bias).Both can be used to adjust the characteristics of the analog input signal to terminal A1.No. Parameter Name Setting Range DefaultH2-06 Watt Hour Output Unit Selection0: 0.1 kWh units1: 1 kWh units2: 10 kWh units3: 100 kWh units4: 1000 kWh units0No. Name Setting Range DefaultH3-01 Terminal A1 Signal Level Selection 0 to 1 0No. Name Setting Range DefaultH3-02 Terminal A1 Function Selection 0 to 31 00.2 sH2-06(Pulse Output Unit)H2-01 to 03㧔Multi-function Output)Integral Power (every 100 ms)OFF OFFONcommon_TMonly
