If you can not move the axis, note the distance from the zero position ( the difference between
the RAPA number and the zero offset number) to the actual position of the axis. Power off,
change encoder, Power up, go to zero offset page in the system parameters, position cursor, press
CAL, enter the difference noted earlier, and press WRITE.
IN POSITION (H)
Sets the in-position width used in positioning the individual axes when executing a tool
change, pallet change, etc. When the axes are moving towards their individual home
positions, the next block of data will be processed when the axes only have the amount
specified in this parameter left to travel to reach their home position.
SWL HD
These four parameters set the position of the horizontal spindle when it is swiveled and
becomes a vertical spindle. This type of spindle head is used on double column ma-
chines. (MCM)
BARRIER (Y,Z)
On horizontal machining centers, if both the Y and Z axes enter a certain area at the same
time, they will interfere with each other. To prevent this, a barrier zone is set up so an
alarm will occur if this happens.
ENCODER OFFSET
This parameter offsets the zero-cross point of the position encoder.
HOME POSITION
These parameters allow the user to machine multiple workpieces on a pallet or table. No.
1, 3, and 4 home positions are reserved for the ATC and APC. No. 1 shows the home
position of the axes when a tool change is performed. No. 3 shows the home positions
when the A pallet is being changed. No. 4 shows the home positions when the B pallet is
being changed.
HOME POSITION MOVEMENT ORDER
Sets up the order in which the axes will move. For example, when a tool change is
performed on a vertical machining center, the Z axis has to move to position first. The
setting range is 0 to 3 with 0 meaning no movement and 1st, 2nd, and 3rd setting the
order in which the axes will move.
