6.2 Motion Command Details
6.2.1 Position Mode (POSING) (Positioning)
6-6
5. Set OW  08 to 0 to execute the NOP motion command to complete the positioning operation.
 Terminology: Command execution
When a command code is stored in the motion command register (OW  08), execution of the motion command correspond-
ing to that code is started. Used in describing motion command operations.
( 2 ) Holding
Axis travel can be stopped during command execution and then the remaining travel can be restarted. A command is
held by setting the Holds a Command bit (OW09, bit 0) to 1.
• Set the Holds a Command bit (OW09, bit 0) to 1. The axis will decelerate to a stop.
• When the axis has stopped, the Command Hold Completed bit (IW09, bit 1) will turn ON.
• Reset the Command Pause bit (OW09, bit 0) to 0. The command hold status will be cleared and the
remaining portion of the positioning will be restarted.
( 3 ) Aborting
Axis travel can be stopped during command execution and the remaining travel canceled by aborting execution of a
command. A command is aborted by setting the Interrupt a Command bit (OW09, bit 1) to 1.
• Set the Interrupt a Command bit (OW09, bit 1) to 1. The axis will decelerate to a stop.
• When the axis has stopped, the remaining distance to be traveled will be canceled, and the Positioning Com-
pleted bit (IW0C, bit 1) will turn ON.
• The positioning will restart if the Interrupt a Command bit (OW09, bit 1) is reset to 0 while the command
is being aborted.
 This type of operation will also be performed if the motion command is changed during axis movement.
 Precautions
Be careful to stop the movement during an axis operation by limiting the torque at OL14 (Positive Side Limiting
Torque Setting at the Speed Reference). When the movement is stopped, the torque is no longer limited and may rap-
idly increase just after stopping. To abort positioning while the torque is limited, use one of the following settings.
• Set the speed reference to 0
• Set bit 0 of OW09 (Motion Command Control Flag) to 0 and set OW08 (Motion Command) to 0 for a
No Operation (NOP) command when the axes stop or turn ON the abort request.
For more information on the maximum allowable value for acceleration and deceleration, refer to  Changing the max-
imum value of acceleration and deceleration for SGDV or SGD7S SERVOPACKs of 4.4.2 ( 23 ).
