Setting 7: DC Bus Undervoltage
Output closes whenever the DC bus voltage or control circuit power supply drops below the
trip level. The undervoltage trip level is determined by L2-05. A fault in the DC bus charge
circuit will also cause the DC Bus Undervoltage output to close.
Setting 8: During Baseblock (N.O.)
Output closes to indicate that the drive is in a baseblock state. While Baseblock is executed,
output transistors are not switched and no voltage will be output.
Setting 9: Frequency Reference Source
A digital output programmed for this function shows the frequency reference source that is
currently selected.
Setting A: Run Command Source
A digital output programmed for this function shows the Run command source that is
currently selected.
Status Description

Closed Baseblock is being executed.
Status Description
Open Frequency reference is provided from External Reference 1 (b1-01) or 2 (b1-15)
Closed Frequency reference is being sourced from the digital operator.
Status Description
Open Run command is provided from External Reference 1 (b1-02) or 2 (b1-16)
