"Spindle in position" signal for tool change
Function
The motion sequence for a tool change, especially for milling machines, mainly comprises positioning the spindle
and then the subsequent (for optimization runs, also at the same time) approach to the tool change position with
the path axes. In this case, the mandatory precondition is that the spindle is reached before approaching the tool
change position.
If the tool change cycle is interrupted by the machine operator (e.g. with an NC stop, NC stop axes plus spindles,
mode group stop etc.), then it must be completely ruled out that the spindle moves into the tool changer at an
incorrect position.
This is the reason that for spindle positioning, when the last programmed spindle position is reached with "Exact
stop fine" the following NC/PLC interface signal is output to check the position:
DB31, ... DBX85.5 (spindle in position)
Setting the signal
Preconditions for output of signal DB31, ... DBX85.5 (spindle in position) are as follows:
• The reference state of the spindle:
DB31, ... DBX60.4/5 (referenced/synchronized 1/2) = 1
• "Exact stop fine" must have been reached:
DB31, ... DBX60.7 (exact stop fine) = 1
Additionally, the last programmed spindle position must have been reached on the setpoint side.
Deleting the signal
When signal DB31, ... DBX60.7 is withdrawn (exact stop fine), then signal DB31, ... DBX85.5 (spindle in position)
is also always reset.
Note
The signal is only output for the "Spindle positioning" function.
This includes:
• SPOS, SPOSA and M19 in the part program
• SPOS and M19 in synchronized actions
• Spindle positioning, using FC18
• Spindle positioning via PLC interface (DB31, ... DBX30.4)
Note
When positioning the spindle, the zero mark is automatically searched for. This is the
reason that for an error-free sequence, the referenced signal is always available at the
end of positioning movement.
