Setting Actual Values From Synchronized Actions - Siemens SINUMERIK 840Di sl Function Manual

On-the-fly transitions in case of axis couplings
Positioning axis motions and movements resulting from axis couplings programmed via
synchronized actions can be activated alternately.

Legal transitions in master value couplings are marked with LEADON in the above table.
Legal transitions in coupled motions are marked with TRAILON.

Setting actual values from synchronized actions

Application
The PRESETON function can be used to redefine the control zero in the machine coordinate
system.
Function
When Preset is applied, the axis is not moved. A new position value is merely entered for the
current axis position.
Programming
The value for one axis can be programmed in each synchronized action.
Example
WHEN $AA_IM[a] >= 89.5 DO PRESETON(a, 10.5)
with PRESETON (axis, value)
Axis: Axis of which the control zero is to be changed
Value: The value by which the control zero is to be changed.
Permissible applications
PRESETON from synchronized actions can be programmed for:
• modulo rotary axes that have been started from the parts program and
• all command axes that have been started from a synchronized action
Restrictions
PRESETON cannot be programmed for axes, which are involved in a transformation.
