Axis travel can be stopped during command execution and then the remaining travel can be restarted.
A command is held by
setting the Command Pause (OB

.

090) to 1. The axis will decelerate to a stop.
When the axis has stopped, the Command Hold Completed bit (IB
091) will turn
ON.
2. Turn OFF the Command Pause bit (OB
090). The command hold status will be
cleared and the remaining portion of the positioning will be restarted.

Axis travel can be stopped during command execution and the remaining travel cancelled by aborting
execution of a command. A command is aborted by setting the Command Abort bit (OB
091) to
1.
Set the Command Abort bit (OB
091) to 1. The axis will decelerate to a stop. When the axis has
stopped, the Positioning Completed bit (IB

This type of operation will also be performed if the motion command is changed during axis
movement.
