9.3.4.4 INTERHARMONICS
A single inter harmonic frequency may be generated using the INTERHARMONICS screen. This
screen allows insertion of any inter harmonic from 1Hz to 2400Hz in 1Hz steps. The amplitude
level of the harmonics range is from 0 to 20% of the programmed voltage. To select the inter
harmonics screen, press the menu screen until the MENU 2 screen appears as shown in Figure
9-34. Select INTERHARMONICS using the up or down key.

1. REFERENCE This field will enable the Inter harmonics generator if ON is selected and
will disable the inter harmonics generation if OFF is selected.
2. REF. COUPL If turned on, the REF. VOLT will follow the programmed voltage value.
3. REF. VOLT This field must be programmed to a value if REF. COUPL is off. This
value has a range from 0 to 230 volts. This value is set to a value
equal to the phase A voltage if the REF. COUPL is turned on.
4. VOLTAGE This field programs the Inter harmonic level in percentage of the
REF.VOLT. This value has a range from 0 to 20%
