Program simulation

3.16.1

Turning simulation and program test

Prerequisite
PLC signal DB19.DBB20.6 is set to 1 when simulation is activated. This signal can be
evaluated for the purpose of switching to program test mode or canceling axis or controller
enabling signals (to prevent axes from moving during simulation runs). The signal is reset to
0 when simulation is terminated.
In order to simulate certain operations during a dry run even though the axis/controller
pulses have been disabled, the transfer of status "Ext. pulse disable active, terminal 663
open" to the NC has to be prevented. The machine manufacturer can achieve this by
evaluating the above-mentioned PLC signal and activating the dry run simultaneously with
NC Start.
If the drive machine data MD1012 $MN_FUNC_SWITCH, Bit 2 is set to 0, the status "Ext.
pulse disable active, terminal 663 open" is not transferred to the NC.

Turning/milling simulation

Using the display-machine data MD9020 $MM_TECHNOLOGY, you define the basic
configuration for the free contour programming of turning/milling.

Milling simulation 3D graphic

This function is a software option named "Milling Simulation", with order number: 6FC5253-
0AE02-0AA0.
If the option is set, the "3D Simulation" softkey will appear and can be used to select the
function.
Operation of milling machine simulation is described in:
