[1] Control details
(1) Teaching timing
Teaching is executed using the PLC program when the BUSY signal (XC,
XD, XE, XF) 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.)
(2) Addresses for which teaching is possible
The addresses for which teaching is possible are "current feed values"
( Md.20 Current feed value) having the OP as a reference. The settings of
the "movement amount" used in incremental system positioning cannot be
used. In the teaching function, these "current feed values" are set in the
Da.6
" Positioning address/movement amount" or "
Positions aligned by manual
control
"Current feed value" A
"Current feed value" B
(3) Dedicated instructions "TEACH 1, TEACH 2, TEACH 3,
TEACH 4, PFWRT"
When the dedicated instructions "TEACH 1, TEACH 2, TEACH 3, TEACH
4, PFWRT" are used to execute the teaching function, the programming
becomes easier. Refer to Chapter 14 "Dedicated instructions" for details.
