Component Definition and Maintenance
The ACB receives all of the Analog Signals from the drive’s internal components.
This includes the current and voltage feedback signals. The boards also have
isolated Digital I/O for fan status, e-stops, and contactor control and status
feedback. All of the test points for the currents, system voltages, control voltages,
and flux are on these boards.
