5-12-1. Measurement of the offset value
∆
Y
Note
•
In the example shown below, the resolution is set to 0.0005 mm.
•
The same applies in the case of RS232C commands.
Also, when an operation is performed using RS232C commands, there is a command that
performs absolute zero point processing directly without setting the absolute zero point mode.
Operating Procedure
Select the Y-axis.
Note
If it is in the INC mode, switch to the ABS mode.
Press the LOAD key.
The arrow indicator flashes.
On contact of the feeler to the machine table,
the buzzer beeps and the counting starts at
the loaded display value.
When the feeler touches the machining table,
the buzzer sounds and the counting starts
from the loaded display value.
The arrow indicator is off.
Check that the REF lamp is on. When it is
not lighted, press the
F
key three times to
select the absolute zero point mode.
Select the Y-axis.
The mark “
” lights up.
Press the HOLD key. The “
/
”
mark and
absolute zero point mode LED flash.
(It is ready for holding the value of the distance
∆
Y to the absolute zero point of scale)
Move the machine spindle and make it pass
over the absolute zero point of the scale. The
buzzer beeps, the mark “
” and the arrow
indicator light and the offset value
∆
Y is held.
The absolute zero point mode LED also light.
∗
By storing the held offset value
∆
Y in memory,
∆
Y can be set easily when the display unit is
replaced. Refer to “5-1-5. Setting offset value
∆
Y”.
Select the Y-axis.
Press the HOLD key.
The mark “
” and arrow indicator go out, the
held display is released, and the spot position is
displayed. At this time, the hold value is stored
internally.
Note
When this processing is performed with an
RS232C command, “H” is replaced by “S”.
