# Zubax Telega ESCs
|
|
|
|
Zubax Telega is a high end, proprietary sensorless FOC motor control technology.
|
|
It is used in multiple products, including the [Zubax Myxa](https://shop.zubax.com/products/zubax-myxa) ESC, [Zubax Mitochondrik](https://shop.zubax.com/products/mitochondrik) motor controller module, and Zubax Sadulli integrated drive.
|
|
|
|
While Telega can be controlled using traditional PWM input, it is designed to operate over CAN bus using [DroneCAN](index.md).
|
|
|
|
::: info
|
|
ESCs based on Zubax Telega require non-trivial tuning of the propulsion system in order to deliver adequate performance and ensure robust operation.
|
|
Users who lack the necessary tuning expertise are advised to either [purchase pre-tuned UAV propulsion kits](https://zubax.com/products#electric-drives) or to use Zubax Robotic's professional tuning service.
|
|
Questions on this matter should be addressed to: [support@zubax.com](mailto:support@zubax.com).

## Where to Buy
|
|
|
|
- [Zubax AmpDrive AD0505A/B "Myxa" ESC](https://shop.zubax.com/products/zubax-myxa): High-end PMSM/BLDC motor controller (FOC ESC) for light unmanned aircraft and watercraft.
|
|
- [Zubax BoolDrive BD1D50 "Mitochondrik"](https://shop.zubax.com/products/mitochondrik): Integrated sensorless PMSM/BLDC motor controller chip (used in ESCs and integrated drives)
|
|
- [Zubax AmpDrive AD0510 "Komar" ESC](https://shop.zubax.com/products/zubax-ad0510-komar-esc): Open hardware reference design for Mitochondrik
|
|
|
|
## Hardware Setup
|
|
|
|
ESCs are connected to the CAN bus using a Pixhawk standard 4 pin JST GH cable.
|
|
For more information, refer to the [CAN Wiring](../can/index.md#wiring) instructions. ESC order does not matter.
|
|
|
|
## Firmware Setup
|
|
|
|
Motor enumeration for [Telega-based ESCs](https://telega.zubax.com/) is usually performed using the [Kucher tool](https://files.zubax.com/products/com.zubax.kucher/) (or less "GUI-friendly" [DroneCAN GUI Tool](https://dronecan.github.io/GUI_Tool/Overview/)).
|
|
Telega does NOT support automatic enumeration by spinning the motor.
|
|
|
|
There is some guidance here: [Quick start guide for Myxa v0.1](https://forum.zubax.com/t/quick-start-guide-for-myxa/911) (Zubax blog).
|
|
|
|
Telega ESCs also require other motor setup and configuration for reliable performance. See the above guide and other Zubax documentation for more information.
|
|
|
|
## Flight Controller Setup
|
|
|
|
### Enable DroneCAN
|
|
|
|
Connect the ESCs to the Pixhawk CAN bus. Power up the entire vehicle using a battery or power supply (not just the flight controller over USB) and enable the DroneCAN driver by setting the parameter [UAVCAN_ENABLE](../advanced_config/parameter_reference.md#UAVCAN_ENABLE) to `3` to enable both dynamic node ID allocation and DroneCAN ESC output.
|
|
|
|
### PX4 Configuration
|
|
|
|
Assign motors to outputs using the [Acutator](../config/actuators.md#actuator-testing) configuration screen.
|
|
|
|
## Troubleshooting
|
|
|
|
### Motors not spinning when armed
|
|
|
|
If the PX4 Firmware arms but the motors do not start to rotate, check that parameter `UAVCAN_ENABLE=3` to use DroneCAN ESCs.
|
|
If the motors do not start spinning before thrust is increased, use [Acutator > Actuator Testing](../config/actuators.md#actuator-testing) to confirm that the motor outputs are set to the correct minimum values.
|
|
|
|
### DroneCAN devices dont get node ID/Firmware Update Fails
|
|
|
|
PX4 requires an SD card for DroneCAN node allocation and during firmware update (which happen during boot).
|
|
Check that there is a (working) SD card present and reboot.
