Reference point
The machine position depends on whether the near point detection limit switch is the plus or minus
side with the near point dog on the machine table as illustrated above as the reference.
When the limit switch exists on the dog, move to either plus or minus.
Using the FEED AXIS SELECT switch, move the machine.
If the limit switch exists in the minus direction as illustrated above, turn ON a plus
FEED AXIS SELECT switch.
For dog mode return to reference position, turn ON the FEED AXIS SELECT switch (+ or –) in the
direction where the dog and limit switch approach each other.
For high-speed reference point return, turn ON the FEED AXIS SELECT switch (+ or –) in the
direction that the spindle head approaches the reference point.
Hold the FEED AXIS SELECT switch ON during return to reference position until the machine passes
by the dog (dog mode) or the REFERENCE POSITION ARRIVAL lamp goes ON (high speed return).
