Alarm handling for single axes
Alarms with an axis parameter are only displayed and not handled as single axis alarms. It is
sufficient to acknowledge these so-called "show alarms" with CANCEL.
Note
Only alarms that have to be cleared again with AXRESET take effect on single axes.
Use Case 1
Cancel operation of axis/spindle
The function Cancel axis/spindle corresponds to the current behavior of the channel-specific
NC/PLC-interface signals:
DB21, ... DBX6.2 (delete distance-to-go)
Use Case 2
Stop axis/spindle
All axis motions controlled by the main run are stopped, thereby interrupting the following
movements:
● Axis/spindle:
● Overlaid movement such as:

Function Manual, 09/2009, 6FC5397-1BP20-0BA0
DB31, ... DBX28.2 (AXRESUME)
DB31, ... DBX28.1 (AXRESET)
Note
The axis/spindle must be operating under PLC control. This supplementary condition
basically applies to all applications: Use cases 1 to 4.
The exchange of signals at the VDI interface during autonomous single operations is
described by means of machine axis 1 in a comparison of PLC actions as the NCK
reaction in Section "Control by the PLC".
