DBX33.7 Program test active
Edge evaluation: No
Signal state 1 Program control program test is active. Axis disable is set internally for all axes (not spindles). There‐
fore 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 user 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.
Signal state 0 Program control "Program test" is not active.
