Programming parameter
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.
3. PWM frequency:
Motor pwm frequency can be programmed between 16kHz and 48kHz. Higher pwm frequency can run motors smoother. Programmable
frequency also allows for moving of small but potentially disturbing humps in the throttle response. All ESCs have these bumps, with BLHeli_32 they can be
moved in the rpm range, to a place where the system has low sensitivity to them.
4. 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.
5. 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.
6. Motor Direction:
Rotation direction can be set to Normal/Reversed/Bidirectional 3D/Bidirectional 3D Rev./Bidirectional Soft/Bidirectional Soft Rev. In bidirec-
tional mode, center throttle is zero and above is fwd rotation and below is reverse rotation. When bidirectional operation is selected, throttle calibration is disabled.
7. Startup Beep Volume:
Sets the strength of beeps under normal operation.
8. Beacon/Signal Volume:
Sets the strength of beeps when beeping beacon beeps. The ESC will start beeping beacon beeps if the throttle signal has been
zero for a giventime. Note that setting a high beacon strength can cause hot motors or ESCs!
9. Beacon delay:
Beacon delay sets the delay before beacon beeping starts.
10.Throttle Cal Enable:
If disabled, throttle calibration is disabled.
11. 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 900us to 2100us input signal, and for the other input signals, the values must be scaled. For Dshot input
signal, these settings have no effect.
12.Thermal protection:
Thermal protection can be enabled or disabled. And the temperature threshold can be programmed .
13.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.
14.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.
15.Current Protection:
This feature is not available
for X-Cross HV 2 series.
16.Current Sense Calibration:
When the current display is not accurate, this value can be adjusted, and the value range is: - 99%
～
154%.
17.Brake on stop:
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
throttle, this setting has no effect.
18.LED Control:
LEDs can be controlled on ESCs that support it.

telemetry requests from the input signal.

All welding requires good welding technology, short circuit between the element or the wire should be avoided
at any time.
●
The shorter the welding of electrolytic capacitor pin, the better, to avoid burning off the pin with high current;
●
If the current is large, it is recommended to weld two capacitors in the accessories on the ESC power supply;
