OPERATION:
Rotating head moves clockwise with
A-B-C-A-B-C pulses and
counterclockwise with A-C-B-A-C-B pulses. Maintaining pressure
in the extended position, locks the rotating head with "Shot
Pin"
accuracy. Use simple non-servo commands from a timing device,
a programmable controller or a computer, see sample program to
the right.. |
