8 Motion Commands
8-10
8.3 External Positioning (EX_POSING)
The EX_POSING command positions the axis to the target position using the specified target position and speed.
Parameters related to acceleration and deceleration are set in advance.
If the external positioning signal turns ON during axis movement, the axis will move the distance specified for
the External Positioning Move Distance from the point at which the external positioning signal turned ON, and
then stop. If the external positioning signal does not turn ON, positioning will be completed to the original target
position.
(1) Operating Procedure
* If the Position Reference Type (OB
095) is set for an absolute mode, the target position can be set
before executing the command.
No.

• The target position can be changed while the axis is moving.
• The target position cannot be changed after the external
positioning signal is input.
• The positioning speed can be changed while the axis is moving.
• An override of between 0% to 327.67% can be set for the position-
ing speed.
• Set OB
090 to 1 to hold the command.
• Set OB
091 to 1 or execute the NOP motion command to abort
the command.
• A latch zone can be set as long as it is supported by the
SERVOPACK being used.
Execute the External Positioning
(EX_POSING) motion command.
• Set OW
08 to 2.
Set the target position.
• Target Position Setting: OL

Turn ON the external positioning signal. The
axis will be moved the External Positioning
Move Distance and decelerate to a stop.
Positioning completed.
