Synchronizing the actual value (homing)
Once the controller enable has been set, the actual position of the machine axis does not need to be
synchronized again (homing) if the maximum permissible limit frequency of the measuring system was not
exceeded during the time in which the machine axis was not in position-control mode.

DB31, ... DBX2.2 (spindle reset (axis/spindle-specific))
"Delete distance-to-go" is effective in AUTOMATIC and MDI modes only in conjunction with positioning axes.
The positioning axis is decelerated to standstill following the current brake characteristic. The distance-to-go of
the axis is deleted.
Spindle reset
