Program control program test is active. Axis disable is set internally for all axes (not spindles).
Therefore the machine axes do not move when a part program block or a part program is being
processed. The axis movements are simulated on the operator interface with changing axis position
values.
The axis position values for the display are generated from the calculated setpoints.
The part program is processed in the normal way.

• Program stopped by M00/M01 or NC stop or operating mode change.
• If single block mode, the block is processed.
• End of program reached (M02/M30).
• Program aborted due to a reset.
• No actual block in the memory (e.g. for MDA).
• The actual block cannot be executed.

The interface signal:
DB21, ... DBX35.0 (program status running)
does not change to 0 if workpiece machining is stopped due to the following events:
• A feed disable or spindle disable was output
• DB21, ... DBX6.1 (read-in disable)
• Feed correction to 0%
• The spindle and axis monitoring functions respond
• Position setpoints are entered in the NC program for axes in "follow-up mode," for axes without
"servo enable," or for "parking axes"
