6.2.8 Overview of Teaching Mode (Teaching Type)
Depending on your system, it may be desirable to be able to use a touch panel, etc., to perform jogging
operation or write the current position to the “Position” field of the position table, without using a PC or teaching
pendant.
The teaching mode (teaching type) is provided to support these applications.
The features of the teaching mode (teaching type) are summarized below:
[1] The actuator can be jogged using I/O signals input from the PLC.
Continuous jog feed or inching feed can be selected by the manual switching signal to facilitate fine position
adjustment.
* This function is effective regardless of the ON/OFF state of the operation mode input (MODE) signal.
[2] The current position can be written to the “Position” field of the position table using I/O signals input from
the PLC.
* This function is effective only when the operation mode input (MODE) signal is ON.
(Note) The number of I/O points is limited, so some I/O ports are used in both the teaching type and the normal
positioning type. Remember this when creating a sequence circuit for the PLC.
Operation mode input (MODE)
* Signal for switching to the teaching mode
ON (teaching mode) OFF (positioning mode)
Current operation mode output (MODES)
* Monitor output indicating the internal
mode of the controller
ON (teaching mode) OFF (positioning mode)

Start input (CSTR)

Write completion output
(WEND) Position complete output
(PEND)
Warning: Jog commands are effective even before home return is completed, but the soft stroke
checks are not performed prior to home return. Accordingly, the actuator may move all
the way to the mechanical end if the jog command (JOG+/JOG-) signal remains ON.
Exercise caution not to let the actuator hit the mechanical end.
