8.8 Teaching Function
The teaching function allows the operator to teach the servo system CPU when the
target position (address) is unknown or to align with an object.
(1) Teaching methods
Two teaching methods are available: "address teaching" and "program
teaching."
(a) Address teaching
Writes the current value to the designated program address.
The program must be created before the address teaching method can be
used.
(b) Program teaching
Writes the current value to addresses while the program is being created.
(2) For details about teaching, see the A30TU-E Teaching Unit Operating Manual
(IB-67277).
