In the case of
STOP with termination
the sequential positioning procedure is
discontinued.
The motion data record address is read in new.
STOP and interruption of the current positioning procedure.
NO STOP:
I0: no STOP
START:
I1: START signal (on edge)
A new START resumes the positioning process at the position where it was
interrupted.
Relationship between the chosen STOP function and the positioning mode
A START flank after previous STOP produces:
- on condition that no STOP (E0=24V) is still present -
Single positioning
Sequential positioning
STOP and termination of
the current positioning
procedure
(
STOP with termination
)
The motion data record address is
read in and the motion data
record is executed.
Note:
In continuous mode a
complete positioning, starting
from the current position, takes
place to the target position
contained in the data record.
The motion data record
address is read in and a
new sequential positioning
procedure is started.
STOP and interruption of
the current positioning
procedure (
STOP without
termination
)
The positioning procedure which was active before the STOP
is continued irrespective of the set motion data record
address.
Position mode in reset operation
In reset operation (activated by the configured reset distance), additional
positioning functions are possible for absolute positionings:
All directions
Standard positioning mode
Positive direction
Positioning only in positive direction
Shortest path
Positioning on the shortest path
Negative direction
Positioning only in negative direction
Actual direction
Positioning by keeping the actual direction of travel
Dynamic positioning
In dynamic positioning, a decision concerning the positioning travel is not taken on
the basis of the actual position, but on the basis of the braking position resulting
from the motion parameters.
In the event of positioning specifications below zero and higher than or equal to
the reset distance, this function is deactivated.
The positioning functions are neither effective in test movements nor in a
positioning after homing travel.
In the event of ”shortest path” the motion is not defined for a positioning by half
the reset distance.

termination
