YASNAC PCNC Programming Manual Chapter 3: Movement Control Commands
Table 3.4.5.3 G Codes That Use I, J, and K Addresses in the Same Block
(b) Relationship with tool radius offset C
If the G codes that are not allowed in the 3-D tool offset mode or modal G codes that must
not be existent at the start of the tool radius offset C are specified in the 3-D tool offset
mode, an alarm occurs. Also note that addresses I, J, and K are used in the 3-D tool offset
mode to define the vector angle. Due to this these addresses must not be used as the
dummy block commands (incremental commands) like in the tool radius offset C.
(c) Relationship with the high-speed cutting function
If high-speed cutting function is called in the 3-D tool offset mode, alarm 0189 “OFS
ABNORMAL ERROR” occurs. To execute high-speed cutting, it is necessary to cancel
the 3-D tool offset mode. If the 3-D tool offset mode is called during high-speed cutting
operation, normal tool radius offset C is executed instead of the 3-D tool offset.
G Code Function Name
G02, G03 Circular interpolation /Circle cut
G106 Automatic corner override
G10 Programmable data input
G22 Stored stroke limit B, C
G65, G66, G67 Macroprogram call
