● Motor Direction : Normal
● Motor Timing : Auto
● Minimum Throttle : 1040
● Center Throttle : 1500
● Maximum Throttle : 1960
● Low Voltage Protection : 3.00V
● Brake On Stop : 100% (Rev 1.1)
● Rampup Power :
Rampup power can be set to relative values from 3% to 150%. This is the
maximum power that is allowed when ramping up at low rpms and during
startup. For low rpms, the maximum power to the motor is limited, in order to
facilitate detection of low BEMF voltages.
Rampup power also affects bidirectional operation, as the parameter is used to
limit the power applied during direction reversal.
● Motor Timing :
Motor timing can be set between approximately 1° and approximately 31°
in approximately 1° increments (actual accurate values here are 15/16ths
of a degree).
This parameter can also be set to auto. In this case the code monitors
demagnetization time,and keeps timing as low as possible without having
issues with demag. On well behaved motors, timing can be low in the entire
power range,and thereby max power can be reduced.On not so well behaved
motors, timing is increased as needed, and thereby improves margins against
sync loss.
● PWM frequency :
Motor PWM frequency can be programmed in a range that is preconfigured by
the ESC manufacturer.

● Rampup Power: 50%
● PWM Frequency : 24kHz
● Throttle Calibration : Enable
● Sine Modulation Mode : Off
● Auto Telemetry : Off
● Beacon Delay : 20:00 Min
● Maximum supported speeds :
For a 48MHz ST MCU, the maximum speeds are approximately:
- Multishot at 8kHz: 510k erpm
- Multishot at 16kHz: 450k erpm
- Multishot at 32kHz: 420k erpm
- Dshot at 8kHz: 470k erpm
- Dshot at 16kHz: 420k erpm
● Demag Compensation :
Demag compensation is a feature to protect from motor stalls caused by long
winding demagnetization time after commutation. The typical symptom is motor
stop or stutter upon quick throttle increase, particularly when running at a low
rpm. As mentioned above, setting high commutation timing normally helps, but
at the cost of efficiency.
Generally, a higher value of the compensation parameter gives better
protection.
If demag compensation is set too high, maximum power can be somewhat
reduced for some motors.
● Sine Modulation Mode :
Sine modulation mode can give a few percent more efficient running, as well as
smoother running.
It is a pretty subtle effect. Power is modulated with a sine shape, following the
top of a sine wave through the commutation cycle so that the power when
commutating shall be ideal for a motor with sine shaped BEMF. Power is varied
between sin(60deg)=87% when commutating to sin(90deg)=100% in the
middle of a commutation cycle, and then down again to sin(120deg)= 87% at
the end of the commutation cycle.
Maximum power is the same for sine mode as for regular mode, as when
approaching full power the ESC will transition smoothly into regular mode.
● Maximum Acceleration :
Maximum acceleration can be set between 0.1%/ms and 25.5%/ms. It can also
be set to maximum, in which case acceleration is not limited. Limiting
acceleration is primarily intended as a backup parameter that can be used in
cases where too hard acceleration gives desyncs.
When setting to e.g. 10%/ms, it means that the power applied to the motor is
not allowed to increase by more than 10% per millisecond.
● Motor Direction :
Motor direction can be set to fwd, rev, bidirectional 3D, bidirectional 3D rev,
bidirectional soft and bidirectional soft rev. In bidirectional mode, center throttle
is zero and above is fwd rotation and below is reverse rotation. When
bidirectional operation is selected, throttle calibration is disabled.There are two
bidirectional modes, bidirectional 3D and bidirectional soft.The 3D mode
applies more power when reversing direction, and also limits minimum throttle

to 6%. The soft mode applies less power when reversing, and does not limit
minimum throttle.
● Startup Beep Volume : Sets the volume of beeps during powerup.
● Beacon/Signal Volume :
Sets the volume of beeps when beeping beacon beeps. The ESC will start
beeping beacon beeps if the throttle signal has been zero for a given time.
Note that setting a high volume can cause hot motors or ESCs!Also sets the
volume used for Dshot / Proshot initiated signal tones.
● Beacon Delay : Beacon delay sets the delay before beacon beeping starts.
● Throttle Cal Enable : If disabled, throttle calibration is disabled.
● Temperature Protection :
Temperature protection can be enabled or disabled. And the temperature
threshold can be programmed. The programmable threshold is primarily meant
as a support for hardware manufacturers to use, as different hardwares can
have different tolerances on the max temperatures of the various components
used.The ESC measures temperature within the MCU and limits motor power if
the temperature is too high. Motor power is limited over a range:
- If the temperature is above the threshold, motor power begins to be limited.
- If the temperature is above the threshold plus approximately 150C, motor
power is limited to 25%. Motor power is not limited below 25%.
● Low RPM Power Protect :
Power limiting for low RPMs can be enabled or disabled. Disabling it can be
necessary in order to achieve full power on some low KV motors running on a
low supply voltage.However, disabling it increases the risk of sync loss, with
the possibility of toasting motor or ESC.
● Low Voltage Protection :
Low voltage protection can be set between 2.5V and 4.0V per lipo cell. Or it
can be disabled.When enabled, it will limit power applied to the motor if the
battery voltage drops below the programmed threshold. This feature is primarily
intended for fixed wing crafts.
● Current Protection :
Current protection can be enabled to limit current. If enabled, then current will
be limited to maximum the programmed value. The reaction time of the current
limiting is quite fast, so current will also be limited during accelerations.
