4. REFERENCE POSITION ESTABLISHMENT
155
When no reference position has been set (APZx, bit 4 of parameter No.
1815, is 0), operations (A) to (E), below, are performed automatically to
set a reference position.
Mechanical
stopper
Current position
(A)The tool is moved along a specified axis with a limited torque until
it butts against the mechanical stopper.
The tool is moved in the direction specified with ZMIx (bit 5 of
parameter No. 1006), at the feedrate specified with parameter No.
7183, at the torque specified with parameter No. 7186 (until the
tool strikes the mechanical stopper).
Mechanical
stopper
The direction, feedrate, and torque
are specified with parameters.
(B)After the tool strikes the mechanical stopper, the tool is withdrawn
in the direction opposite to the butting direction, along the axis for
a parameter–set distance.
The tool is moved in the direction opposite to that specified with
ZMIx (bit 5 of parameter No. 1006), at the feedrate specified with
parameter No. 7185, for the distance specified with parameter No.
7181.
Mechanical
stopper
The direction, feedrate, distance,
and torque are all specified with pa-
rameters.
(C)Operations (D) and (E) are performed from the withdrawal point,
such that the tool is butted against the mechanical stopper at a
constant feedrate in reference position setting.
(D)The tool moves along the specified axis at a specified torque until
it butts against the mechanical stopper.
The tool moves in the direction specified with ZMIx (bit 5 of
parameter No. 1006), at the feedrate specified with parameter No.
7184, at the torque specified with parameter No. 7186 (until the
tool strikes the mechanical stopper).
