(2) Change the mode to the manual mode, and move the tool by a
manual operation (jog feed, incremental feed, manual handle
feed, or manual numerical command) for a purpose such as the
purpose of changing the tool. This operation is called manual
retraction. The CNC automatically records the retract path of
the tool. Up to 10 points on the tool retract path are recorded
automatically. When the tool is retracted manually, the TRSPS
signal is set to "0". While the tool is moving along an axis by
manual operation, the TRMTN signal is "0".

(3) Restore the automatic operation mode, and set tool return signal
TRRTN to "1" then back "0". The CNC then reverses the tool
along the path of the manual movement to return the tool to the
retract position. This operation is called recovery. When the
tool starts moving for recovery, TRMTN is set to "1". Upon
completion of the recovery to the retract position, TRSPS is set
to "1". The recovery is performed at the dry run feedrate.
