12 CONTROL AUXILIARY FUNCTIONS
12.7.4 Teaching function
The "teaching function" is used to set addresses aligned using the manual control
(JOG operation, manual pulse generator operation) in the positioning data addresses
(
Da.5
Positioning address/movement amount,
Da.6 Arc address).
The details shown below explain about the "teaching function".
(1) Control details
(2) Precautions during control
(3) Data used in teaching
(4) Teaching procedure
(1) Control details
(a) Teaching timing
Teaching is executed using the sequence program when the BUSY signal
(X4, X5, X6) is OFF. (During manual control, teaching can be carried out as
long as the axis is not BUSY, even when an error or warning has occurred.)
(b) Addresses for which teaching is possible
The addresses for which teaching is possible are " Md.29 Current feed
value" having the zero point as a reference. The settings of the "movement
amount" used in increment system positioning cannot be used. In the
teaching function, these "current feed values" are set in the "
Da.5
Positioning address/movement amount" or "
Da.6 Arc address".

control
"Current feed value" A
Da.5

amount
"Current feed value" B
Da.6
Arc address
(c) Teaching target axis (
Cd.4
Target axis)
Teaching can be executed for the "designated axis only" or the "2 axes
carrying out interpolation control". When teaching is executed for the "2
axes carrying out interpolation control", the "current feed value" is set for
both the reference axis and the interpolation axis.
