Troubleshooting Guide
Problem ESC
Tones
Possible
Causes
Solution
Motor won’t
operate and
continues to
emit tones
Two short
tones
repeating
Input voltage
is beyond the
operating range
of the ESC
Ensure the operating
voltage is within the
specs for the ESC
One long
tone
repeating
The ESC is
not receiving
a throttle
signal from the
receiver
Verify the transmitter and
receiver are connected,
check the throttle lead
is in the correct servo
port, and check channel
assignments
One short
tone
repeating
The throttle
input is not at
the low position
Move the throttle
control to the low
position
Throttle range is
set too narrow
Re-calibrate the
throttle range
Throttle Signal Loss Protection:
When the ESC detects loss of signal for over 0.25 second,
it will cut off power to the motor immediately. The ESC will
resume normal operation when throttle signals are received.
Overload Protection:
The ESC will cut off power to the motor if there is a sudden
load that exceeds predetermined limits.
Over-current Protection:
The ESC will cut off power to the motor if the peak current
goes above the rated value.
Low-voltage Cutoff Protection:
The ESC will limit the output to 60% when the input voltage
drops below the LVC value.
