6.7 Setting Reference
This function allows user to set a machine zero point. With this machine zero point users
can restore the work coordinates even if the machine is moved when the DRO is in OFF
condition. Generally each encoder has reference marks present at every specified interval.
One of these reference marks is used to recall the same datum point every time.
This function works only in ABS mode. It will not be executed in INC mode.
6.7.1
Homing reference
In this function, the Datum is set at the reference mark on the encoder. Follow the
procedure for the homing reference.
1. Press [
] key.
2. The soft key menu displays {
}, {
} and {
}.
3. Press {
} The Information Bar message window displays “SELECT AXIS”
4. Axis will display ‘Homing....’ Message. Move the slider to the reference point
5. After crossing reference mark DRO will start counting. Your reference is now set.
Note:
It is highly recommended to mark an indicator on the encoder so as to use the
same reference mark while finding the datum point.
6.7.2
Recalling machine reference
In this function, the Machine reference is recalled as set in the user setup. Follow the
procedure for the Machine reference.
1. Press [
] key.
2. The soft key menu displays {
} and {
}.
3. Select {
}. The Information Bar message window displays ‘SELECT AXIS’
4. Press the required axis [
] key. The selected axis displays 'M/C REF.’.
5. Move the axis to the reference point on encoder which was used for setting machine
reference.
6. Now the DRO will display the ‘distance to go’ for machine reference position.
7. Now if you will move the slide to make the DRO reading zero, you will achieve the
machine reference position.
6.7.3
Setting the machine reference
1. Press {
} key to set machine reference
The screen displays the message
“homing...”
Move the slider to the reference point
on encoder.
Mark this reference position for future use.
