Reading and changing frame components (TR, FI, RT, SC, MI)

Function
This feature allows you to access individual data of a frame, e.g., a specific offset value or
angle of rotation. You can modify these values or assign them to another variable.
Syntax
R10=$P_UIFR[$P_UIFNUM,X,RT]
R12=$P_UIFR[25,Z,TR]
R15=$P_PFRAME[Y,TR]
$P_PFRAME[X,TR] = 25
Significance
$P_UIFRNUM
P_UIFR[n,...,...]
TR
FI
RT
SC
MI
X Y Z
Value range for RT rotation
Rotation around 1st geometry axis:
Rotation around 2nd geometry axis:
Rotation around 3rd geometry axis:
300
Assign the angle of rotation RT around the X axis
from the currently valid settable zero offset
$P_UIFRNUM to the variable R10.
Assign the offset value TR in Z from the data
record of set frame no. 25 to the variable R12.
Assign the offset value TR in Y of the current
programmable frame to the variable R15.
Modify the offset value TR in X of the current
programmable frame. X25 applies immediately.
This command automatically establishes the reference to the
currently valid settable zero offset.
Specify the frame number n to access the settable frame no. n.
Specify the component to be read or modified:
TR Translation
FI Translation Fine
RT Rotation
SC Scale scale modification
MI mirroring
The corresponding axis X, Y, Z is also specified (see
examples).
-180° to +180°
-90° to +90°
-180° to +180°
