z Response
If the data has been changed (written) successfully, the response is the same as the query.
[Function]
When the PWRT signal changes from “0” to “1” while in the teaching mode (MODE = “1”) and this condition is
maintained for 20 msec or more after it is recognized by the controller, the current position data will be written to the
target position corresponding to the position number in the command position number register effective at the time of
detection.
If the position table is empty, the default parameters will be written together in the data fields other than the target
position (positioning band, speed, acceleration/deceleration).
z Actual Example (Axis 0)
Load the teaching position into No. 8 of the axis (0) position table.
