CHAPTER 8 MACHINE ZERO RETURN OPERATION
8.1 Machine Zero
The machine coordinate system
is a basic coordinate system for CNC coordinate calculation. It is
an inherent coordinate system of the machine. The origin of the machine coordinate system
is called
machine zero
(or machine reference point). It is defined by the zero return switches fixed
on the machine. Usually the switch is fixed on the positive max. Strokes of X, Y, Z axes.
Note: the mechanical zero is called “machine zero”.
8.2 Machine Zero Return Steps
1. Press
key, it enters the Machine zero mode, the bottom line of the screen page shows
“REF”, the figure is shown below:
2. Press
or
or
key to select the machine zero of X, Y or Z axis
3. The machine moves along the machine zero direction, and returns to the machine zero via the
deceleration signal, zero signal detection. And the axis stops with the machine zero finish indicator
lighting up.
Machine zero finish indicators
Note 1
:
If the machine zero is not fixed on the machine, machine zero operation B/C/D is unallowed.
Note 2
:
While the coordinate is moved out from the machine zero, the machine zero finish indicators go out.
Note 3
:
After the machine zero operation, the cancellation of the tool length offset for the
CNC is set by the BIT7 of the bit parameter No.13
Note 4
:
See details in the 3rd part INSTALLATION AND CONNECTION for the parameters concerning with
the machine zero.
Note 5: When machine zero return, bit parameter
№
011 ZNIK determines whether axis movement is locked
automatically.
