8.8 STEP Operation (STEP)
The STEP command executes a positioning for the specified travel direction, moving amount, and travel speed.
Parameters related to acceleration and deceleration are set in advance. The speed can be changed during axis
movement.
(1) Operating Procedure
(2) Holding
Axis travel can be stopped during command execution and then the remaining travel can be restarted. A com-
mand is held by setting the Command Pause bit (OB
090) to 1.
1. Set the Command Pause bit (OB
090) to 1. The axis will decelerate to a stop. When the axis has
stopped, the Hold Completed bit (IB
091) will turn ON.
2. Reset the Command Pause bit (OB
090) to 0. The command hold status will be cleared and the remain-
ing portion of the positioning will be restarted.
(3) Aborting
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
01C) will turn ON.
This type of operation will also be performed if the motion command is changed during axis movement.
