FANUC tapping interrupt processing:
Rigid tapping retraction:
No5202#1 Set to 1, select G30 tapping return
0: Execute address signal G62.6 tapping retreat
1: Execute G30 tapping rollback of G code
Rigid tapping retraction based on G30 command (suitable for retraction after power failure):
① After the system is powered off during tapping, power it on again.
② Type in MDI mode (or automatic mode):
G30P99M29Sxxx; xxx is the spindle speed when tapping before power off.
③The system automatically generates and executes tapping retraction action.

Mitsubishi tapping interrupt processing:
In the Mitsubishi system, after the attack speed is interrupted, there will usually be:
1.0057 alarm: Alarm while waiting for TAP reset
2. And the three axes will be locked and unable to move.
Approach:
1. First check whether there is tapping retraction in the PLC switch. If so, turn it on directly to realize tapping retraction.
2. If there is no tapping return item in the PLC switch, you can force YC5C to equal 1 in the IF diagnostic interface, and it will automatically return to point R.

Siemens tapping interrupt processing:
Siemens 828D/840DSL after version 4.5 all come with tapping rollback function.
