both traversing directions at the
servo-amplifier-potentiometer “velocity”
(Tacho-return) as good as is possible
to a value which corresponds to the
entered KV-factor and the programmed
raoid feed rate.

For pre-adjustment, the trailing error (lag) can
be adjusted to the feed rate indicated on the display.
