12. POSITION SWITCH
12.1 OUTLINE OF FUNCTION
The position switch (PSW) is used as an alternate switch for the dog switch provided on an axis of the
machine. The position switch uses parameters by which the names of axes and their corresponding
coordinates indicating imaginary dog positions are defined in advance. When the machine reaches the
imaginary dog position‚ a signal is output to the PLC interface. The position switch thus works as an
imaginary dog switch.

switching of
position switch
Specify whether to perform position
switch area checking at high speeds.
0: Do not perform position switch area
checking at high speed (do it the
same as before).
1: Perform position switch area
checking at high speed.

751 <axis> Axis name Specify the name of the axis for which a
position switch is provided.
X, Y, Z, U, V, W, A,
B, or C axis address
752 <dog1> Imaginary dog
position 1
753 <dog2> Imaginary dog
position 2
When the machine enters the range
between imaginary dog positions 1 and
2, a signal is output to the PLC.

754 <check> Selection of area
check method
When position switch area checking at
high speed is selected, specify the mode
of area checking, i.e., whether to use the
command type machine position or
detector feedback position, for each
position switch point.
0: Use the command type machine
position as the machine position for
position switch area checking.
1: Use the detector feedback position
as the machine position for position
switch area checking.
Note: This parameter is valid only when
1 set in "#7500 Pcheck."
