2. PREPARATIONS FOR OPERATION
250
[Classification] Output signal
[Function] Indicates that the tool post interference alarm is activated.
[Output condition] This signal goes “1” when:
(i) The control unit judges that the two tool posts will interfere with each
other during the execution of the tool post interference check function.
This signal goes “0” when:
(i) The control unit judges that the two tool posts will not interfere with
each other during the execution of the tool post interference function.
(ii)When the tool post interference check function is not being performed
(i.e., the TICHK signal is “0”).
NOTE
1 During the execution of the interference check function, if
the control unit judges that the two tool posts will interfere
with each other, it stops both tool posts by slowing them
down, and then enters the alarm state. The CNC then sets
the TIALM signal “1” to indicate that an interference alarm
has occurred.
2 If the interference alarm is occured, switch the operation
mode to the manual mode, manually withdraw the tool posts
to where they do not interfere each o ther, then release the
alarm status b y resetting the control unit.
As the result of manually withdrawing the tool posts, the
TIALM signal goes “0” when the control unit judges that the
tool posts are separated enough not to interfere with each
other any more. When manually withdrawin g the interfering
tool posts, the TIALM signal is effective in identifying how far
the tool posts must be separated from each other. This is
because it is easy for the operator to check at the point
which the signal goes “0”.
3 If an interference alarm occurs, the axis being moved and
its moving direction are stored, and the axis cannot be
moved in the stored direction until the alarm is released by
resetting the control unit. This prevents the axis from
interfering any further by prohibiting movement in the
direction that caused the interference.
