Not true. For instance, my universal PWM controller (and my
universal stepper controller with the Gecko interface) will not
lose the position reference even during an abrupt stop, or a
crash. The reason is that the motor position is fed back from
the encoders all the way to the computer. So, even a servo
fault doesn't interrupt the encoder position count.
