Introduction | Status displays
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 7
Active datum shift (Cycle 7); the control
displays an active datum shift in up to 8 axes
Mirrored axes (Cycle 8)
Active rotation angle (Cycle 10)
Active scaling factor/factors (Cycle 11 / 26); the
control displays an active scaling factor in up to
6 axes
Scaling datum
In the optional machine parameter CfgDisplayCoordSys
(no. 127501) you can specify the coordinate system in
which the status display shows an active datum shift.

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 control
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 and 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 .
