The Analog Control Board (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 e-stops, contactor control
and status feedback. All of the test points for the currents, system voltages,
control voltages, and flux are on these boards.
