The 1-axis is returned to zero point when PX3 is turned ON, and the 2-
axis is returned to zero point when PX4 is turned ON.
Check that the in-position signal is turned ON, and that the start accept
signal is turned OFF before starting the zero point return program.
* To allow the "K141" to be started during execution of "K140", this
program is structed so that there is no WAIT command to wait for the
completion of zero point return after the motion control step. (This
program must contain the start accept for each axis in the interlock
conditions, so that K140 and K141 do not start simultaneously.)
