m
Normal relative target setting, in contrast, depends on the positive edge of the Start bit.
A new target position is generated relative to the old position when the positive edge
of the Start bit occurs.
m
On-the-fly relative target setting also depends on the positive edge of the Start bit. A
new target position is generated relative to the instantaneous actual position when the
positive edge of the Start bit occurs.
m
With absolute unlimited target setting (Target Mode = 3, not limited to maximum travel
amplitude) positioning is carried out in the direction of the shorter path to the target.
The maximum traversing range can be exceeded if the software limit switch function is
off.
With the trapezoidal and S-Curve profiles, new positioning data (target position, position-
ing speed, positioning acceleration, etc.) can also be activated while in motion.

Position-
ing Record Number Actual, on-line changes must also be made here. The changes take
effect immediately if

the Start bit is set and
m
no positioning error (e.g. hardware limit switches active) is present.
If one of the positioning records 1 to 16 is selected in the current set number, on-line
changes can be made in the selected set. The data from the selected positioning set are
copied completely into Positioning Set 0 and take effect when, in addition to the two con-
ditions above,

Alternatively, Positioning Set 0 can be written to directly. The basic values of the ad-
dressed positioning set then remain unchanged during the on-line changes. Thus only the
speed can be changed at a relative positioning, too. The effective target position remains
unchanged.
