I've built an oversized F550 with a NAZA M2 controller and E600 motors.
When I plug in the battery I get an endless BB---BB---BB---BB from all six motors.

The documentation states that the beep codes indicate "Input voltage is abnormal"

Does anyone know what's causing these beeps? I can't go any further with my build until I solve this problem.

1st, You posted this in the Heli section. NAZA M stuff should be in the Multirotor section. You'll get more / better responses there.

On my NAZA M builds, when I plug in the battery, I get that tone until I power the NAZA (have a seperate switch for control power). The NAZA will then boot and the motors will emit the 1-2-3 (or is it 4) tone, indicating ready to initialize.

I would be looking to see that the NAZA M is powered correctly and all your "servo wires" are plugged into the NAZA in the correct orientation (yellow wire toward notch).
Are you using the PMU?
Did you plug the PMU into the correct port (X3) of the NAZA M, in the correct orientation? (Yellow wire toward the notch)
Does the PMU have battery power applied to it? (check with meter)
Is there power coming from the PMU (check w/ meter)?
What battery are you using? (NAZA M V2 likes the 4S batteries)
Does the LED light up and if so, what color and does it flash?

If battery power is applied and everything is correctly wired, may be a bad PMU not powering the MCU correctly.

Have you plugged in USB to the NAZA Assistant? If yes, do you see any thing on the screens?
