When the MODE signal is turned ON, the normal operation mode is changed to the teaching
mode.
When the mode is changed to the teaching mode, the MODES Signal is turned ON.
After confirming that the MODES signal is turned ON on the PLC side, start the teaching
operation.
(Note): In order to change the normal operation mode to the teaching mode, the following
conditions are required.
x
The actuator operation (motor) is stopped.
x
The + JOG (JOG+) signal and – JOG (JOG-) signal are turned OFF.
x
The Position Data Import Command (PWRT) Signal and Positioning Start (CSTR) Signal are
turned OFF.
(Note): When the PWRT signal is not turned OFF, the mode is not returned to the normal

The PWRT signal is available when the teaching mode signal (MODES) is turned ON.
Turn ON the PWRT signal
(Note1)
, Then, the current position data will be written in the position
data box for the position No. set using the PLC's specified Position No. channel.
(Note2)
When the data writing is completed, the WEND signal is turned ON.
After the WEND signal is turned ON, turn OFF the PWRT signal in the host machine.
When the PWRT signal is turned OFF before the WEND signal is turned ON, the WEND signal
is not turned ON.
When the PWRT signal is turned OFF the WEND signal is also turned OFF.
Note1: Turn it ON for 20msec or more. If the time is shorter than 20msec, the writing is not
completed.
Note2: When the data items except for the position have not been defined, the parameter
initial values are written. [Refer to Chapter 7 Parameter]
