Start position for simulation and simultaneous recording
During simulation, the start position is converted via the zero offset to the workpiece coordinate
system.
The simultaneous recording starts at the position at which the machine is currently located.
Constraint
● Referencing: G74 from a program run does not function.
● Alarm 15110 "REORG block not possible" is not displayed.
● Compile cycles are only partly supported.
● No PLC support.
● Axis containers are not supported.
● Swivel tables with non-swiveling offset vectors are not supported.
Supplementary conditions
● All of the existing data records (tool carrier / TRAORI, TRANSMIT, TRACYL) are evaluated
and must be correctly commissioned for correct simulation.
● Transformations with swiveled linear axis (TRAORI 64 - 69) as well as OEM transformations
(TRAORI 4096 - 4098) are not supported.
● Changes to the tool carrier or transformation data only become effective after Power On.
● Transformation change and swivel data record change are supported. However, a real
kinematic change is not supported, where a swivel head is physically changed.
● The simulation of mold making programs with extremely short block change times can take
longer than machining, as the computation time distribution for this application is
dimensioned in favor of the machining and to the detriment of simulation.
Example
An example for supported kinematics is a lathe with B axis:
