Dualsky Summit X Series User manual

● 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.
- Dshot at 32kHz: 310k erpm
- Proshot at 8kHz: 480k erpm
- Proshot at 16kHz: 430k erpm
- Proshot at 32kHz: 330k erpm
- Dshot at 16kHz with sine: 280k erpm

Instruction Manual
Programming parameters
● 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.

Time
● Minimum throttle, maximum throttle and center throttle :
These settings set the throttle range of the ESC. Center throttle is only used for
bidirectional operation. The values given for these settings are for a normal
1000μs to 2000μs input signal,and for the other input signals, the values must
be scaled.
For Dshot/Proshot input signal, these settings have no effect.
● Brake On Stop :
Brake on stop can be set between 1% and 100%, or disabled. When not
disabled, the given brake force will be applied when throttle is zero. For
nonzero throttle, this setting has no effect. This feature is primarily intended for
fixed wing crafts with folding props.
On some ESCs this setting is not linearly programmable, it will just be enabled
(at 100% force for any setting 1%-100%) or disabled (this applies to ESCs that
have “EN/PWM” style fet drivers).
● Auto Telemetry :
When auto telemetry is enabled, the ESC will autonomously output telemetry at
32ms intervals, regardless of whether or not there are telemetry requests from
the input signal.
● LED Control : LEDs can be controlled on ESCs that support it.
● Regenerative braking / active freewheeling :
Damped light mode is implemented by doing regenerative braking, and
inherently active freewheeling is also implemented. Then losses due to braking
are counteracted by the reduced losses of active freewheeling.It is possible to
select nondamped operation (for most ESCs). This will degrade performance in
multirotor applications but can be desirable for fixed wing environments.
● S.BUS :
S.BUS as input signal is supported. The S.BUS channel is selected with
SUMMIT X Android app. If a valid S.BUS channel (0 to 16) is selected, then the
input signal will be interpreted as S.BUS.
Telemetry is supported. Telemetry is designed to be compatible with the
specifications from KISS 24A, and delivers the following data:
- Temperature [°C] - Voltage [V] - Current [A]
- Temperature [Ah] - Rotation speed [electrical rpm]
Temperatures below 0°C are not supported, they will be shown as 0°C.
For conversion from electrical rpm to mechanical rpm, divide by (motor poles)/2.
Telemetry
At power on, an activated ESC beeps 3 beeps.
When throttle signal is detected, it beeps one low tone beep. This signals that input
signal is detected. Then, when or if throttle is zero, it beeps one high tone beep.
This signals the end of the arming sequence, and the ESC is ready to run.
Also, if more than 50% throttle is detected at arm start, the ESC starts throttle
calibration.If the esc is armed and sees zero throttle for a given time, it beeps
beacon beeps, which are approximately one beep per three seconds.
The figure below shows an example of throttle value versus time.

Failures
● Beeps - Not activated ESC :
All ESCs shall be activated during manufacturing.
If for some reason this is not done, the ESC will beep like this upon
powerup, before the normal operation beep sequence starts:
● Beeps - Activation failed ESC :
All ESCs shall be activated during manufacturing.
If for some reason activation has failed and the ESC is not regarded as a
valid SUMMIT X unit, the ESC will beep like this upon powerup, before the
normal operation beep sequence starts:
In this case the ESC will only accept 1-2ms pwm input signal.
