11.3.2 Motion Command Details
Basically, the SVR provides functions to loop from a Motion Command (OW
08) to the Servo 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
OE)
• Target Position (CPOS) (IL
10)
• Machine Coordinate System Position (MPOS) (IL
12): MPOS is always equal to CPOS.
• Machine Coordinate Feedback Position (APOS) (IL
16): APOS is always equal to CPOS.
No.
