Re: [CAD_CAM_EDM_DRO] servo control

When the motor is not in motion, the servo watches for any motion, and
pushes the motor back
where it was. This uses the same idea as motion, but you want 0 speed, so
the system takes the
speed-you-got and the speed-you-want and calculates the error-of-speed. This
is converted to
a control voltage and sent to the amp. The motor 'fights' its way back to
where it was supposed
to be.
There has to be a sensor to detect the motion or speed and a calculation
and an output to the amp.
