Operation manual for BLHeli SiLabs Rev10.x

Normal operation:

This procedure is used for PWM input signal.

Power up:

Once

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):

Once

After this, the motor will run.

Normal operation:

This procedure is used for PPM input signal.

Power up:

Once

Throttle signal detected (arming sequence start):

Once

Zero throttle detected (arming sequence end):

Once

After this, the motor will run.

Entering programming mode:

This procedure is used for PWM input signal.

Power up:

Once

Throttle up detected (arming sequence start):

Once

Full throttle detected (start of entering programming mode):

Infinite

Zero throttle detected (continue entering programming mode):

Infinite

Full throttle detected (programming mode entered):

Once

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.

Throttle range calibration and entering programming mode:

This procedure is used for PPM input signal.

Power up:

Once

Throttle signal detected (arming sequence start):

Once

When throttle is above midstick (measuring max throttle):

While measuring

If throttle is above midstick for 3 seconds:

Once

This beep sequence indicates that max throttle has been stored

When throttle is below midstick (measuring min throttle):

While measuring

If throttle is below midstick for 3 seconds:

Once

This beep sequence indicates that min throttle has been stored

At this point throttle calibration values are stored. You may remove power from the ESC, if you just wanted to do a throttle calibration and not enter programming mode.

Full throttle detected:

Once

This beep sequence indicates that programming mode is entered

Programming mode:

Function 1, parameter value 1

Once

Function 1, parameter value 2

Once

…etc…

Function 2, parameter value 1

Once

…etc…

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 load the defaults and then reset itself after the last parameter value of the last function. This is a convenient way of setting all parameters to defaults.

If power is disconnected during the programming sequence, then no changes are done to the programmed values.

*: Governor arm mode is only supported with PWM input signal

**: Default startup method and power varies by ESC. Generally the stepped start is used for the original mCPX ESCs, and generally the default power is lower for larger ESCs.

Default values are marked in bold green.

If for some reason there is an error in the eeprom/flash write operation (e.g. due to loss of power or low voltage), defaults will be loaded.
