bit0: Switching to actual cutting mode during automatic operation
[M8]
0: Unable to switch to actual cutting mode or no-load operation mode during automatic operation.
Block stop is executed before a speed change-disabled command (thread cut or tap).
1: Able to switch to actual cutting mode or no-load operation mode during automatic operation.
Block stop is not executed before a speed change-disabled command (thread cut or tap).
[C80]
Not used.
bit1: Speed selection for other part systems during actual cutting mode
[M8]
0: Other part systems operate at the programmed speed in the same manner as the part system where a
speed change-disabled command (thread cut or tap) is given.
1: Other part systems operate at the program check speed.
[C80]
Not used.
bit2: Prohibit reverse run of fixed cycle
[M8]
Select whether to prohibit reverse run of a fixed cycle during manual arbitrary reverse run.
0: Permit reverse run
1: Prohibit reverse run
(Note) Even when the parameter is "1", reverse run is enabled during fixed cycle operation.
[C80]
Not used.
bit3: Prohibit MSTB reverse run
[M8]
Select whether to prohibit reverse run of MSTB during the manual arbitrary reverse run.
0: Enable MSTB reverse run
1: Disable MSTB reverse run
(Note) Even when the parameter is "0", MSTB reverse run is disabled while the MSTB reverse run prohibit
signal (MRPSG) is ON.
[C80]
Not used.
bit4: Thread cut start shift angle operation
Select the operation to be performed at the start of thread cutting when a thread cut start shift angle com-
mand is issued.
0: Start thread cut from the thread cut start shift angle after phase Z has been detected once.
1: Start thread cut from the thread cut start shift angle, independently of phase Z detection.
bit7: Storage of spindle C axis coordinate system
Select whether to automatically insert zero return to spindle/C axis control at the initial servo ON or at every
servo ON. This parameter is enabled when spindle/C axis deceleration stop type (#3106 zrn_typ/BIT8=1)
and zero point return automatic insertion (#1226 aux10/BIT3=1) are selected.
0: Execute automatic zero return before C axis rotation for the first C axis command given after every servo
ON.
1: Execute automatic zero return before C axis rotation for the first C axis command given after the initial
servo ON. For the 2nd and subsequent servo ON, the coordinate system is retained after servo OFF,
and zero return is not automatically inserted.
