Instead of the dog switch provided on the machine axis‚ the coordinate values indicating imaginary dog
positions (dog1 and dog2) on the coordinate axis of the axis name preset with axis are set with the position
switches (PSW1 – PSW24). When the machine reaches the position‚ the signal is output to the device
corresponding to the PLC interface.
Example of settings of dog1 and dog2 and operation
Setting of dog1 and
dog2
dog1, dog2 position Operation
dog1 < dog2
dog1 dog2
A signal is output between
dog1 and dog2.
dog1 > dog2
dog2 dog1
A signal is output between
dog1 and dog2.
dog1 = dog2
dog1 = dog2
If dog1 equals dog2‚ the
dog1 position triggers a
signal.
