Remedy
• Check the specifications.
• Correct the program.
• Issue the spindle speed command (S) when
the tapping fixed cycle command G84, G74
(G84, G88) is given.
• Check connection to the main spindle unit.
• Check that the main spindle encoder exists.
• Specify the pitch data and the number of
threads by F or E command.
• Check the pitch or the number of threads per
inch.
• Check the specification.
• Delete the lathe cutting cycle command.
• The radius command value in the lathe
cutting cycle command must be smaller than
the axis shift amount.
• Set a chamfering amount not exceeding the
cycle.
• Check the specification.
• Delete the following G codes from this
subprogram that is called with the compound
type fixed cycle I commands (G70 to G73):
G27, G28, G30, G31, G33, fixed-cycle
G-code.
• Remove G02 and G03 from the first move
block of the finish shape program in multiple
fixed cycle I.
• The number of blocks in the shape program
called by the compound type fixed cycle I
commands (G70 to G73) must be decreased
below 50.
