Axis Operating Flags
An Axis Operating Flag will turn ON when the axis is operating. An operating
axis is an axis that is being given a command value to move the axis.
For example, when the axis is being operated with a trapezoidal curve, the
axis is operating from the start of the acceleration command to the end of the
deceleration command.
Use the Axis Operating Flag to determine when the axis has stopped after
executing a Deceleration Stop Command.
Timing Chart The following example shows a trapezoidal reference output to the motor.
