Atmel BLHeli SiLabs Operation manual Rev6.x
Operation manual for BLHeli SiLabs Rev6.x
Normal operation:
Power up:
Once
Throttle needs to be minimum before arming starts
Throttle up detected (arming sequence start):
Once
The maximum throttle in this interval sets the”arm” target for the governor.
Zero throttle detected (arming sequence end):
After this, the motor will run.
Once

Entering programming mode:

Throttle up detected (arming sequence start):
Full throttle detected (start of entering programming mode):
Zero throttle detected (continue entering programming mode):

The above description is for main.
For the tail, follow the same sequence, but use right rudder as full throttle and left rudder as
zero throttle.

If the throttle stick is moved to zero during one of the above sequences, the parameter value
of that function is selected and stored. And you will hear this sound:
Parameter value stored
Once
The ESC then resets itself.
If the throttle stick is moved below max (but not to zero), the current parameter will be
skipped, and programming will proceed to the next parameter. This way it is possible to
access the later parameters without going through all the beeps.
It is generally a good idea to go to full throttle again before selecting a parameter, to make
sure you have selected the right parameter.
Throttle is read in the 1 second pause between the function/parameter beeps.
If the throttle stick is never moved to zero, the ESC will reset itself after the last parameter
value of the last function. Then no changes are done to the programmed values.
If power is disconnected during the programming sequence, then no changes are done to the
programmed values.
