E70 Series Instruction Manual
4.4 Manual Reference Position Return Mode
II - 15
If the return direction is erroneous in high-speed reference position return, an alarm occurs.
A return is made to the reference position at the rapid traverse feedrate.
(1) Using the MODE SELECT switch, select the reference position return mode.
(2) Using the RAPID TRAVERSE OVERRIDE switch, set arbitrary override value.
The machine position depends on whether the near point detection limit switch is on 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.
For dog mode reference position 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 position return, turn ON the FEED AXIS SELECT switch (+ or -) in the direction that the spindle
head approaches the reference position.
Hold the FEED AXIS SELECT switch ON during reference position return until the machine passes by the dog (dog
mode) or the REFERENCE POSITION ARRIVAL lamp goes ON (high speed return).
Operation procedure
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.
