Please note while programming:

Note that all functions for tilting in the working plane are

reset. M128 or FUNCTION TCPM are switched off.
Position the calibration sphere on the machine table so

that there can be no collisions during the measuring

process.
Before defining the cycle you must set the datum in the

center of the calibration sphere and activate it, or you

define the input parameter Q431 correspondingly to 1 or 3.
If MP6602 is not equal to –1 (PLC macro positions the

rotary axes), only start a measurement if all rotary axes are

at 0°.
For the positioning feed rate when moving to the probing

height in the touch probe axis, the TNC uses the value

from cycle parameter Q253 or MP6150, whichever is

smaller. The TNC always moves the rotary axes at

positioning feed rate Q253 while the probe monitoring is

inactive.
If the kinematic data attained in the optimize mode are

greater than the permissible limit (MP6600), the TNC

shows a warning. Then you have to confirm acceptance of

the attained value by pressing NC start.
Note that a change in the kinematics always changes the

preset as well. After an optimization, reset the preset.
In every probing process the TNC first measures the

radius of the calibration sphere. If the measured sphere

radius differs from the entered sphere radius by more than

you have defined in MP6601, the TNC shows an error

message and ends the measurement.
If you interrupt the cycle during the measurement, the

kinematic data might no longer be in the original condition.

Save the active kinematic configuration before an

optimization with Cycle 450, so that in case of a failure the

most recently active kinematic configuration can be

restored.
Programming in inches: The TNC always records the log

data and results of measurement in millimeters.
The TNC ignores cycle definition data that applies to

inactive axes.
