3. Programming parameters and instructions
** Startup power differs with different ESC. Usually, bigger ESC has bigger startup power.
Dark grey cell is the default set.
If error occurs during saving/re set process due to some reason, e.g power disconnected, low
voltage etc, default settings will be re loaded.
1).Startup power
Can be set to relative values from 0.031 to 1.5. This is the maximum power that is allowed during
startup. Actual applied power depends on throttle input, and can be lower, but the minimum
level is a quarter of the maximum level.
Startup power also affects bidirectional operation, as the parameter is used to limit the power
applied during direction reversal.
2).Tempreture protection
The ESC measures temperature within the MCU and limits motor power if the temperature is too
high. Motor power is limited in four steps:
- If the temperature is above 1400C, motor power is limited to 75%.
- If the temperature is above 1450C, motor power is limited to 50%.
- If the temperature is above 1500C, motor power is limited to 25%.
- If the temperature is above 1550C, motor power is limited to 0%.
3).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.
4).Motor direction
Rotation direction can be set to fwd/rev/bidirectional fwd/bidirectional rev.
In bidirectional mode, center throttle is zero and above is fwd rotation and below is reverse
rotation. When bidirectional operation is selected, programming by TX is disabled.
