Hi Kalyan,
1, 2, 3. It might be due to improper motor identification or the speed loop tuning. Try to run the motor identification procedure once again. It’s recommended to carry out motor identification without a propeller.
4. No, Kucher doesn’t display plots. Please, use UAVCAN GUI Tool instead.
5. Myxa is rated for 51V indeed. But the warning appears at 50.4 V, because if the voltage is higher, there is a risk that the voltage will exceed the maximum allowable when the motor is decelerated quickly.
6. You can read more about the speed loop tuning in the instructions for tuning in the RPM control mode.
Try to increase the m.spup_curr_begn parameter for more reliable motor start. It increases the spinup motor torque.
Myxa doesn’t and won’t support UAVCAN over the USB. The main interface in Myxa and other Telega based ESCs is UAVCAN over CAN. USB is used just for quick setup.
