Tool setting mode

This mode of operation allows functions such as
system alignment, tool calibration, length and
diameter tool setting, and thermal compensation
tracking.
No M-codes are required.
High-speed tool breakage
detection
This mode of operation allows rapid detection of
broken tools that are solid at the centre – for
example, drills and taps.
An M-code is required to activate the tool
breakage detection mode. The M-code must
supply a constant voltage of between 12 V and
24 V to CN2-11. To deactivate the tool breakage
function, the 12 V to 24 V supply must be
removed from CN2-11.

Operating modes

These selection levels can be inverted using
switch SW3-1, so that 0 V is used to activate tool
breakage detection and 12 V to 24 V is used to
deactivate. If the M-code voltage is floating when
deactivated, a resistor is required to pull up the
voltage to 12 V to 24 V (see the figure below).

Latch mode

This mode of operation allows functions such as
checking tools for missing inserts and profile
checking.
