IP 266
Table 2-3 shows the conditions under which the "Position Reached" signal is set.
Table 2-3. Switching Conditions for the "Position Reached" Signal
Absolute and relative target specifications:
• Position setpoint must have reached the target coordinate
and
• Actual position lies within the tolerance range of zero-speed
monitoring (beginning at time t
Premature termination of a job with absolute or relative target
specification
A residual distance remains until a new machining operation
is started. A subsequent machining request with the distance
to go shown positions the drive to the original target position
In machining programs, the termination of machining operations
or dwells is indicated by the "Position Reached" signal.
During execution of a machining program
• when a dwell is aborted
• when a traversing movement is aborted
In "1/2 jog" following a Stop command
"Controlled jog" when the actual position no longer changes in a
sampling interval
