Chapter 9 Parameter Descriptions
The imbalance in amps is calculated as the larger of:
(largest phase current) – (average phase current), or
(average phase current) – (smallest phase current).
The imbalance in percent is calculated as:
(Imbalance in amps) ÷ (average phase current) x100.

Captures and displays RMS motor amps at the time of the last fault.
Captures and displays the DC bus voltage of the drive at the time of the last fault.
Captures and displays Drive Status 1 bit pattern at the time of the last fault.
