Hello everyone,
I have a fundamental doubt. I am wondering of how is it possible to have a position control of a servo using digital encoders? how to send an absolute position command when we don't know the current position?
for example: we would always give a relative position command when the servo is operating using digital encoder. suppose if we start a servo from some intermediate position, how to command it to go to the desired position when we don't know the intermediate position? This is unlike potentiometers which any time can tell the current position without movement of the motor.
Please help me to solve the confusion.
thanks in advance.
