PGM-SECTION CANNOT BE SHOWN

• Enter a smaller tool radius.
• 4D and 5D movements cannot be graphically simulated.
• Enter a tool axis for simulation that is the same as the axis in the definition of the workpiece blank.

PLANE WRONGLY DEFINED

• Do not change the tool axis while a basic rotation is active.
• Correctly define the main axes for circular arcs.
• Define both main axes for I,J (JK, IK).

PROBE SYSTEM NOT READY

• Be sure the transmitting/receiving window of the TS 630 is oriented to the receiving unit.
• Check whether the touch probe is ready for operation.

PROGRAM-START UNDEFINED

• Begin the program only with a G99 block.
• Do not resume an interrupted program at a block with a tangential arc or if a previously defined pole is needed.
• Program the first block with axis motion with G00 G40 G90.

RADIUS COMP. UNDEFINED

Enter radius compensation G41 or G42 in the first subprogram for Cycle G37 CONTOUR GEOMETRY.

ROUNDING-OFF NOT PERMITTED

Enter tangentially connecting arcs and rounding arcs correctly.

ROUNDING RADIUS TOO LARGE

Rounding arcs must fit between contour elements.
