[Data type] Bit
G84 Method for specifying rigid tapping
0 : An M code specifying the rigid tapping mode is specified prior to the
issue of the G84 (or G74) command. (See parameter No.5210).
1 : An M code specifying the rigid tapping mode is not used. (G84
cannot be used as a G code for the tapping cycle; G74 cannot be used
for the reverse tapping cycle.)
VGR Any gear ratio between spindle and position coder in rigid tapping
0 : Not used (The gear ratio is set in parameter No.3706.)
1 : Used (The gear ratio is set by parameters Nos. 5221 through 5224 and
5231 through 5234.)
NOTE
For serial spindles, set this parameter to 0 when using the
DMR function for position coder signals on the spindle side.
CRG Rigid mode when a rigid mode cancel command is specified (G80, G01
group G code, reset, etc.)
0 : Canceled after rigid tapping signal RGTAP is set to “0”.
1 : Canceled before rigid tapping signal RGTAP is set to “0”.
SIG When gears are changed for rigid tapping, the use of SIND <G032 and
G033> is
0 : Not permitted.
1 : Permitted.
DOV Override during extraction in rigid tapping
0 : Invalidated
1 : Validated (The override value is set in parameter No.5211.)
PCP Rigid tapping
0 : Used as a high–speed peck tapping cycle
1 : Not used as a high–speed peck tapping cycle
FHD Feed hold and single block in rigid tapping
0 : Invalidated
1 : Validated
SRS To select a spindle used for rigid tapping in multi–spindle control:
0 : The spindle selection signals SWS1 and SWS2 (bits 0 and 1 of G027)
are used. (These signals are used also for multi–spindle control.)
1 : The rigid tapping spindle selection signals RGTSP1 and RGTSP2
(bits 4 and 5 of G061) are used. (These signals are provided expressly
for rigid tapping.)
