    There might be situations where external isolation components might be needed. Veronte MC110 can be mounted in different ways in order to reject the airframe vibration. The simplest way CAN be achieved by just using double-sided tape on the bottom side of MC110. Other ways may use some external structure which could be rigidly attached to the airframe and softly attached to Veronte (e.g.

    NINE TROUBLESHOOTING 9.1 How to confirm that the MC110 is able to read a PWM signal Warning: For safety reasons, it is better to do this test without the motor connected or powered. Power up the controller via user cable, without connecting the motor or the input power. If the input command is higher than the deadband, the MC will start to control (even though there is no motor connected).
