[Data type] Bit
RDC A canned cycle for high-speed positioning and drilling is:
0 : Disabled.
1 : Enabled.
BCR In a boring cycle, retraction is made:
0 : At a cutting feedrate.
1 : At a rapid traverse rate.
FCK In a multiple repetitive canned cycle (G71/G72), the machining profile
is:
0 : Not checked.
1 : Checked.
If this parameter is specified, the machining profile specified in the
multiple repetitive canned cycle for lathe (G71/G72) and the
machining start point are checked. If the relationship is incorrect, the
P/S 062 alarm is raised.
An incorrect relationship between the machining profile and
machining start point indicates either of the following cases.
• Although the finishing allowance is specified with a positive sign,
the start point of the canned cycle is smaller than the maximum
value of the machining profile.
• Although the finishing allowance is specified with a negative
sign, the start point of the canned cycle is larger than the
minimum value of the machining profile.
NOTE
1 The machining profile is checked before the
operation of the canned cycle (not during
machining).
2 The machining profile to be checked is a
programmed profile. The path of retraction or return
is not checked.
3 This parameter is not valid for G71 or G72 of the
canned cycle for grinder.
SPE In a multiple repetitive threading cycle in the FS10/11 tape format,
single-edge thread cutting and both-edge zigzag thread cutting with
the depth of cut kept constant:
0 : Cannot be specified.
1 : Can be specified.
MCC In a multiple repetitive turning canned cycle (G71 or G72), whether an
illegal arc is specified or not is:
0 : Not checked immediately before the start of a movement.
1 : Checked immediately before the start of a movement.
