Verify the TPS signal is changing from 0 to 100% by controlling the servo from idle
to “WOT” position.
Warring: The reading of OnTime_ServoPWM_In should be from 0.6 to 2.3ms
for the Futaba S3016 which comes from Ecotros’ EFI.
If the reading is lower than 0.6, and higher than 2.3, please reinstall the
servo motor. Because of the reasonable control range is 0.6-2.3ms, if it is
out of this range the servo motor will not work correctly.
1.8 Control Servo motor
Note: It will be the custom UAV engine EFI kit If you want our ECU to control servo motor,
please contact us to get the custom kit.
Note: ECU controls servo motor by the “auto-pilot” of the UAV, via a PWM signal.
1) The default duty cycle of servo control PWM signal is 20ms.
2) The default pulse width is 0.5-2.5ms, but if the pulse is 2.5ms, the servo will rotate in
360 degrees. So the correct range is 0.6-2.3ms to protect the servo motor.
3) The rotation angle is about 180 degrees, so please don’t rotate the servo more than
180 degrees.
4) Do not incorrectly connect the wires of the servo motor.
