■ H2-06: Watt Hour Output Unit Selection
When 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 the
frequency 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.

◆ H3: Multi-Function Analog Inputs
The drive is equipped with three multi-function analog input terminals: A1, A2, and A3. See Table 5. 39 for a listing of
the functions that can be set to these terminals.
■
H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1.
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and
bias settings will be simply read as 0%.
Setting 1: –10 to 10 Vdc
The input level is –10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then
the motor will rotate in reverse.
■
H3-02: Terminal A1 Function Selection
Determines the function assigned to analog input terminal A1. Refer to Multi-Function Analog Input Terminal Settings
on page 237 for instructions on how to adjust the signal level.
■
H3-03, H3-04: Terminal A1 Gain and Bias Settings
Parameter 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.
