Hello, POWER – maximum voltage supplied to the motors (0 - 255, where 255 means full battery voltage). Choose this parameter according to your motor characteristics. Basic tuning: ◦ Motors should not get too hot! Motor temperatures of over 80С will cause permanent damage to motor magnets. ◦ A Power value that is too low will not provide enough force for the motor to move the gimbal and stabilize the camera adequately. A low power value will be most noticeable in windy conditions, when the gimbal is not well balanced, or if the gimbal suffers from mechanical friction. Slowly lower the Power parameter to find its optimal value. Find the lowest value that still provides good stabilization and adequate holding torque. ◦ Raising the power equals raising the “P” and “D” value of PID settings. If you raise the POWER value, you should re-tune your PID values as well.
No, but you should get rid of the I2C errors, they will lower the performance.
Measure the motor. disconnect it and measure between each pin, the resistance should be about same, between 10 and 20 ohms depending of motor, but same between each pin. Measure also between motor metal parts and any pin, there should be no resistance.
