14.34.2.1 Operation Function: Automatic Mode

The axis is positioned automatically.
The axis will be positioned at the designated station by turning ON Operation start (ST).
The arbitrary position command operation is also available: the positioning can be carried out to any position other than a
station by directly commanding the positioning coordinates from the PLC. (Refer to the explanations of the arbitrary
coordinate designation method.)
Preparation
Set the following signals before operation.
Abbreviation Signal name
AUT Automatic operation mode

 Turn OFF Operation start (ST) when the positioning has been completed.
Turning OFF Operation start (ST) during the positioning makes the axis be positioned at the nearest station from the cur-
rent position.
 The following signals will be output when the positioning has been completed:
Automatic set position reached (JSTA), Set position reached (JST), Near set position (NEAR), and Station position (STO1
to STO256).
IB-1501668-B
Use this signal to select automatic operation mode.
Setting two different operation modes at the same time will cause the operation
error (M01 0101).
Keep this signal ON during automatic mode.
Set the rotation direction based on the direction of station No. assignment.
This signal setting is not available when short-cut control is enabled.
The operation will be issued at the automatic operation speed (aux_Aspeed)
and acceleration/deceleration time constant(aux_timeN.1, aux_timeN.2) of the
selected operation group.
Set the station Nos. to be used for positioning.
Setting "0" (special station No.) will start the special operation mode.
Value at ST's ON is valid
"0" is output
