8.3.2 Motion Command Details
Basically, the SVR provides functions to loop from a Motion Command (OW
08) to the Motion
Command Type Response (IW
08).
For positioning-related motion commands, the SVR updates position information toward the final
target position using a positioning function.
( 1 ) Positioning (POSING)
The 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.
The speed and target position can be changed during operation. When the target position is changed
so that there is not sufficient deceleration distance or after the new target position has already been
passed, the system will first decelerate to a stop and then reposition according to the new target
position.
[ a ] 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.
(Note) The following position information is updated during command execution.
• Machine Coordinate Target Position (TPOS) (IL
0E)
No. Execution Conditions Confirmation Method
1 There are no alarms.
Both IL
02 and IL
04 are 0.
2 The Servo ON condition.
IB
001 is ON.
3 Motion command execution has been completed.
IW
08 is 0 and IB
090 is OFF.

• The target position can be changed while the axis is moving.
• The positioning speed can be changed while the axis is moving.
• Set OB
090 to 1 to hold the command.
• Set OB
091 to 1 or execute the NOP motion command to abort the
command.
Execute the positioning (POSING) motion
command.
