Main features

● RM 32-bit Cortex MCU, frequency up to 64 MHZ, 25% higher than the previous generation of MCU.

● PWM frequency up to 128k, high frequency for higher throttle makes running smoother.

● ESC ﬁrmware is optimized, makes the throttle linearity smoother and the response faster.

● Supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and

Multshot (5- 25us). The input signal is automatically detected by the ESC upon power up.

● All Dshot and Proshot signals are supported .

● Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active

freewheeling.

● Small size and light weight, support higher KV motor and more power load .

● The output of the modular BEC can supply power to the receiver, steering gear and other external devices,

which makes the application of the ESC more extensive;.

● Adjustable BEC output 5V / 3A or 12V / 2A , more ﬂexible application

Programming parameter

Programming parameters below can be accessed from the conﬁguration software (BLHeliSuite32).

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.

During startup, the actual applied power depends on throttle input, and can be lower than the maximum level set by the rampup power parameter, but the

minimum level is a quarter of the maximum level.

2. 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). Typically a medium setting will work ﬁne, but if the motor stutters it can be beneﬁcial to increase timing. Some motors with high inductance

can have a very long commutation demagnetization time. This can result in motor stop or stutter upon quick throttle increase, particularly when running at a low

rpm. Setting timing to high will allow more time for demagnetization, and often helps. Motor timing can also be set to auto.

3. PWM frequency:

Motor pwm frequency can be programmed in a range. Support variable pwm frequency where the pwm frequency is controlled by motor RPM.

-Low frequency for low throttle gives good active braking where it is most needed

4. Demag compensation:

It 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.

5. Sine Modulation Mode:

Sine modulation mode can give a few percent more eﬃcient running &smoother running. Note: if sine mode is chosen, then variable pwm frequency is disabled.

6. Maximum Acceleration:

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.

7. Motor Direction:

center throttle is zero and above is fwd rotation and below is reverse rotation. When bidirectional operation is selected, throttle calibration is disabled.

12. Min throttle, max 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

1000us to 2000us input signal, and for the other input signals, the values must be scaled. For Dshot input signal, these settings have no eﬀect.

13.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.

14.Low RPM power protect:

running on a low supply voltage. However, disabling it increases the risk of sync loss, with the possibility of toasting motor or ESC.

15.Low Voltage Protection:

battery voltage drops below the programmed threshold. This feature is primarily intended for ﬁxed wing crafts.

22.S.BUS:

If a valid S.BUS channel (0 to 16) is selected, then the input signal will be interpreted as S.BUS.

23. S.PORT:

If a valid S.PORT physical ID (1 to 28) is selected, then the telemetry format will be S.PORT. Note that only ESCs that use USART1 (port PB6) for

29x14x9mm

telemetry support S.PORT. If the "S.PORT Physical ID" programming parameter shows up in BLHeliSuite32, then your ESC supports it.

Attentions

●

ESC will automatically detect the input throttle signals every time as

soon as it powered on, and then execute the corresponding signal-

receiving mode.

●

User need to calibrate the throttle range when starting to use a new

ESC or another transmitter.

● Please don't ﬂash any other ﬁrmware to avoid product damage.

● Observe polarity at all times. Double check before applying power.

● Power oﬀ before unplugging ,plugging in or making any connections.

● Please do not exceed the current & voltage range.

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

It can be enabled,disabled or on adaptive. Disabling it can be necessary in order to achieve full power on some low kV motors

It 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

Some ESCs do not support this function，For these ESC, the settings have no eﬀect.

Brake on stop can be set between 1% and 100%, or disabled. When not disabled, brake will be applied when throttle is zero. For nonzero

When it is enabled, the ESC will autonomously output telemetry at 32ms intervals, regardless of whether or not there are telemetry

It can be set to normal or relaxed. Relaxed increases the risk of damage to ESC or motor but can recover faster when props hit obstacles.

Damped light mode is implemented by doing regenerative braking, and inherently active freewheeling is also implemented. Then
