[Data type] Bit
ACR When rigid tapping is specified in AI advanced preview control/AI
contour control mode, the mode is:
0 : Not turned off.
1 : Turned off.
When the serial spindle does not support advanced preview control of
rigid tapping, AI advanced preview control/AI contour control mode
must be turned off in rigid tapping.
Setting this parameter and satisfying the following conditions can
automatically turn AI advanced preview control/AI contour control mode
off only during execution of rigid tapping when rigid tapping is specified
in AI advanced preview control/AI contour control mode.
Conditions
D To specify rigid mode, use “the method for specifying M29 S****
prior to the tapping command.”
If a method other than the above is used, P/S alarm No. 5110 is issued.
D The interval between M29 (rigid mode specification M code) and the
completion signal (FIN) must be at least 32 msec.
D The rigid mode cancel command and cutting feed move command
cannot be specified simultaneously. If they are specified
simultaneously, P/S alarm No. 5110 is issued.
(Additional information: The rigid mode cancel command and rapid
traverse move command can be specified in the same block.)
D Set bit 2 (CRG) of parameter No. 5200 to 0.
(This setting specifies that rigid tapping mode is canceled when the
rigid tapping signal RGTAP is set to “0”.)
