Mitsubishi Electric MELDAS 600M Series Instruction Manual page 344

Operation procedure
Using the MODE SELECT switch, select
the reference point return.
Using the RAPID TRAVERSE
OVERRIDE switch, set any desired
override value.
Check the current
machine position.
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 for 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 reference point return, 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 reference point until the machine passes by the dog
(dog mode) or the REFERENCE POINT ARRIVAL lamp goes ON (high speed return).
