The direction of spindle rotation after the gear change is determined by the PLC-program with the
markers M2485 to M2487 (see "Direction of spindle rotation").
Machine parameter MP3030 can be used to determine whether an axis-halt should occur on a TOOL
CALL with only a spindle speed output.
If an axis-halt is not permitted, then no PLC-positioning, datum-correction, spindle-orientation or
change of limit switch range may be performed during the S-code output.

1 = No axis-halt on TOOL CALL
0 = Axis-halt on TOOL CALL
If a non-permissible spindle speed is programmed, the marker M2092 will be set by the NC, and
simultaneously the error message "Wrong spindle speed" is displayed.
