Use caution when endpoints are set to high values that may exceed the servos physical capabilities. This is true of both analog and digital servos, but for different reasons. Most analog servos will hit physical stops if they are set too far in either direction. Hitting the stop strains the servo and causes excessive current draw from the battery. In extreme cases the servo motor may become compromised to the point of failure if it is strained too much.

Some digital servos have a different issue where the servo stops driving the motor if the position pulse is outside the operational range of the servo. This can be detrimental in extreme cases because the tendency for a pilot would be to extend the position pulse further out of bounds while the vehicle plummets into the ground.

Make sure your servos can handle extended position pulses if the endpoints are set much beyond 150% of normal. Test the servo operation  by setting the endpoints on the SM2 Control Panel Application and using the "Program Device" function to set the endpoints on the SM2. It is advisable to find out where your particular equipment stops working (if it ever does stop), and keep well within those operational boundaries.

Use the "High Endpoint" and "Low Endpoint" slider-bars to set servo endpoints.
