Coordinate transformations (TRANS tab)
Soft key Meaning
Name of the active datum table
Active datum number ( #), comment from the
active line of the active datum number ( DOC)
from Cycle G53
Active datum shift (Cycle G54); The TNC
displays an active datum shift in up to 8 axes
Mirrored axes (Cycle G28)
Active basic rotation
Active rotation angle (Cycle G73)
Active scaling factor/factors (Cycles G72); The
TNC displays an active scaling factor in up to 6
axes
Scaling datum

Displaying Q parameters (QPARA tab)
Soft key Meaning
Display the current values of the defined Q
parameters
Display the character strings of the defined
string parameters
Press the Q PARAMETER LIST soft key. The TNC
opens a pop-up window. For each parameter type
(Q, QL, QR, QS), define the parameter numbers you
wish to control. Separate single Q parameters with
a comma, and connect sequential Q parameters
with a hyphen, e.g. 1,3,200-208. The input range per
parameter type is 132 characters.
The display in the
QPARA tab always contains eight
decimal places. The result of Q1 = COS 89.999 is
shown by the control as 0.00001745 for example.
Very large or very small values are displayed by
the control in exponential notation. The result of
Q1 = COS 89.999 * 0.001 is shown by the control as
+1.74532925e-08, whereby e-08 corresponds to the
factor of 10 -8 .
