Fulcrum Pro/Pro+ 300A Brushless Speed Controller Manuals www.hifei.com
Low voltage cut-off can protect battery from discharging too low and causing permanent
damaged to battery, especially important for Lithium polymer cells. It is strongly recommend to set the
LVC carefully before running.
The setting is to set low voltage cut-off of each Lipo cell.
‘Sensitivity’ setting is low over-current threshold, will shut down rapidly.
‘Standard’ is moderate over-current threshold, will shut down after a slight delay.
‘Insensitivity’ is high over-current threshold, will shut down after a slight delay. Recommend
only experienced modelers would change to use this programming feature.
‘Close’ current limiting detection disabled. only experienced modelers would use this option.
‘Brake disabled’ setting will close the brake function;
‘Soft brake’ will provide 20% of full braking power.
‘Low timing’ setting adjusts the timing at the range of 0º~15º, recommended for more lower
pole count brushless motors (such as 2 poles, or 4 poles). It gives more power and slightly less efficient;
‘Middle timing’ adjusts the timing at the range of 5º~20º, recommended for most brushless
motors. It gives a good balance of power and efficiency;
‘High timing’ adjusts the timing at the range of 15º~30º, recommended for higher pole count
motors. (such as 8, 10, 12, 14 poles or higher brushless outrunner motor)
‘Auto timing’ setting is automatically adjust the timing degree according to motor’s rotating
demand.
0°; 2°; 4°; 6°; 8°; 10°; 12°;14°; 16°; 18°; 20°; 22°; 24°; 26°; 28°; 30° are specific options for

Cutoff type settings decide the way in which the ESC cutoff output to brushless motor when
the LVC works, or temperature/ signal-lost protection works.
‘Hard cutoff’: when the battery volts discharges to the set LVC value or soft protection
works, the motor will shut down immediately. Motor can be restarted by closing the throttle to the
lowest position and re-move the throttle as normal.
‘Soft cutoff’: when the battery volts discharges to the set LVC value or soft protection
works, the ESC will slowly reduce motor power to zero, you will notice a decrease in power and it is
time to dock.
‘Soft start’: very soft and smoothly start the motor, it will take more time.
‘Standard start’: start the motor at normal speed, it depends on the motor’s quality and
dynamic response.
‘Fast start’: start the motor fast, recommend this for racing.
.
‘Auto’ recommended for general fixed-wing aircraft.
‘Low RPM’ recommended for collective pitch helicopters. Used for low pole count motors
and low RPM on higher pole count motors.
‘High RPM’ recommended for collective pitch helicopters. Used for higher pole count
motors and higher RPM.
Note:
a. The poles mentioned above is the magnetic poles of brushless motor, not the stator numbers of
motor.
b. It is strongly recommended to have bench testing and choose appropriate parameters for your
configuration before assembling the ESC to hull for running.
