Advanced Setup
To achieve optimal product life and avoid reaching the thermal throttle limits of the UHV, the following design considerations of your application should be made to reduce the risk of damaging the ESC.
Avoid the use of adhesives on the UHV that may insulate the heat-generating components or case when attaching the ESC or attaching a heat sink.
Ensure there is sufficient air-flow passing over the UHV aluminium casing. We recommend the ESC is positioned in an area where it can be actively cooled by propeller wash for example (in a helicopter use case). Mounts for externally power fans are also available.
Confirm that the wires selected for the power inputs and motor output terminals are appropriately rated for the anticipated current draw.
Check that the terminals are screwed securely up to 3.9Nm.
Once the ESC is connected to a motor and powered on, the following sequences of tones give statuses and errors as they occur. The tones occur in either high or low beeps (high and low frequency). The output of the tones can be disabled with the motor beep toggle, under Advanced in the configuration tool
Tone Sequence | Indication |
3 High, 1 High, 1 Low | PWM or ProShot detected + Armed |
6 Fast High Tones (5-second repeat) | No signal detected or signal above arming point for the ESC |
1 High (10-second repeat) | Normal operation, waiting for arming throttle signal |
3 High (10-second repeat) | Thermal limit exceeded last flight, shut down occurred |
4 High (10-second repeat) | Under-voltage event occurred last flight, shut down occurred |
5 High (10-second repeat) | Over-voltage event occurred last flight, shut down occurred |
