"Delete distancetogo (axial)"
After the axes have been stopped with "Delete distancetogo" the next program block is prepared
with the new positions. The axes thus follow a different contour to the one originally defined in the
part program after a "Delete distancetogo".
If G90 is programmed in the block after "Delete distancetogo" it is at least possible to approach the
programmed absolute position. On the other hand, with G91, the position originally defined in the
part program is not reached in the following block.

Application
example(s)
The binary-coded index of the parameter set to be activated is located in the 3 bits:
• 0 corresponds to the 1st parameter set
• 1 corresponds to the 2nd parameter set
• etc. (max. 6 parameter sets are possible)

DBX20.1 Rampfunction generator fast stop
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
A fast stop is triggered by the PLC for the drive (611D). Speed setpoint 0 is therefore entered. The
drive is stopped without a ramp function (regenerative braking).
As soon as the fast stop is recognized by the drive module, the interface signal:
DB31, ... DBX92.1 (Ramp-function generator fast stop active) is returned to the PLC.
