performs the same movement as the tool center point control type1 in
(2).
(2) Start-up with movement command
(When orthogonal coordinate axis command is issued in the same block)
(a) Tool center point control type1, type2
When the tool center point control is ON, the tool center point moves only as much as it is
ordered under the incremental value command.
