Introducció
This manual provides detailed instructions for the installation, operation, and maintenance of your Hobbywing XERUN Axe R3 Combo, which includes the Axe R3 Electronic Speed Controller (ESC) and the 4274-1700KV Field Oriented Control (FOC) motor. Please read this manual thoroughly before using the product to ensure correct setup and safe operation.
Informació de seguretat
Adhering to the following safety guidelines is crucial for preventing damage to the product and ensuring user safety:
- Ensure all wires and connections are properly insulated before connecting the ESC to related devices. Short circuits can cause severe damage to your ESC.
- Verify that all devices within the system are connected correctly to prevent any system damage.
- Review the manuals for all power devices and the chassis to confirm the power configuration is correct prior to using this unit.
- Use a soldering iron with a power rating of at least 60W for soldering all input/output wires and connectors.
- Do not allow the external temperatures of the ESC and motor to exceed 90°C (194°F), as high temperatures can damage both components.
- The battery must be disconnected after use. A small current draw exists even when the system is off, which can fully drain the battery over time. This may damage the ESC and will not be covered under warranty.
