Syntax x x T H
Parameters
Description x x [int] A x i s number.
Range x x 0 to 8.
Units x x N o n e .
Defaults x x M i s s i n g : 0 .
Out of range: E r r o r B.
Floating point: E r r o r A.
Description T h i s command reads the theoretical position and the instantaneous real
position. If the axis specifier xx is missing or set to 0, the controller returns
the desired position for all axes.
The command could be sent at any time but its primary use is while a
motion is in progress.
The command is useful in determining the following error of a motion
device by comparing the theoretical position to its real position.
Returns x x T H n n or XX ITHnni, xx2THnn2, x x 8 T H n n 8
xx, xxi, xx2, x x 8
— A x i s number.
nn, n n 2 , n n 8
— Theoretical position, in predefined units.
Errors A — U n k n o w n message code.
B — I n c o r r e c t axis number.
S — Communication time-out.
Rel. Commands T P — R e a d actual position.
Example
3TP,3TH I R e a d real and theoretical position on axis #3.
3TP .5.322 I C o n t r o l l e r returns real position 5.322 for axis #3.
3TH .5.323 I C o n t r o l l e r returns theoretical position 5.323 for axis #3.
