Core Features
3.1
Silent Sine Wave Mode
When the controller has hall sensors connected, the 3 phase output drive
waveform is sinusoidal rather than trapezoidal. On most direct drive hub motors,
this means a butter smooth feeling as you apply the throttle rather than the
normal buzz or growl you may be used to. And even on geared motors the
audibly sound from the hub is somewhat reduced.

LED Indicator
The LED status indicator lets you know if the controller is powered up, what state
it's in, and most importantly if there are any fault conditions that would cause
things not to work. The following are normal operating modes:
LED Off
No power to controller (either battery is disconnected,
or ON/OFF switch is OFF)
LED Slow Flash
Controller powered up, throttle is not pressed or it is
running but in sensorless mode
LED Steady On
Controller is running the motor in sensored mode
The following state flash signals occur with quick blinks and then a pause. Note
though that in sensorless mode, the error flash codes may not be visible due to
the regular blinking that happens when running sensorless:
3 Blinks
Controller is in over voltage fault
4 Blinks
Battery voltage below low voltage cutoff
5 Blink
Brake cutoff is engaged
6 Blinks
Throttle either too high or engaged when controller
turned on
