Please note while programming:
Before running Cycle 440 for the first time, you must have
calibrated the TT tool touch probe with the TT Cycle 30.
Ensure that the tool data of the calibrating tool has been
entered in the tool table TOOL.T.
Before running the cycle, you must activate the calibrating
tool with TOOL CALL.
Ensure that the TT tool touch probe is connected to input
X13 of the logic unit and is ready to function (MP65xx).
Before you perform a measurement, you must have made
at least one calibration, otherwise the TNC will output an
error message. If you are working with several traverse
ranges, you have to make a calibration for each of them.
The TNC calculates incorrect values if the probing
directions for calibrating and measuring do not
correspond.
Each time you run Cycle 440, the TNC resets the result
parameters Q185 to Q187.
If you want to set a limit for the axis shift in the machine
axes, enter the desired limits in the tool table TOOL.T
under LTOL for the spindle axis and under RTOL for the
working plane. If the limits are exceeded, the TNC outputs
a corresponding error message after a control
measurement.
After the cycle is completed, the TNC restores the spindle
settings that were active before the cycle (M3/M4).
