RETRACAC (P133)
It indicates whether retracing is allowed or not
If RETRACAC = 2, only the M0 is executed; the rest of the M functions are not sent out to the PLC,
it neither executes them nor interrupts the withdrawal. The [CYCLE START] key must be pressed
after executing M0.
Retracing is activated and deactivated with the RETRACE (M5051) signal. This function may also
be activated while function G51 (look-ahead) is active.
If while executing a part program, the PLC sets this signal high, the CNC interrupts the execution
of the program and starts executing backwards what has executed so far.
When the PLC sets the RETRACE signal back low and retracing is canceled. The CNC will resume
forward execution of the blocks that it executed backwards and goes on to the part of the program
that had not machined.
G15SUB (P134)
It is used on the lathe model CNC. Indicates the number of the subroutine associated with function
G15.
When there is an associated subroutine, the CNC acts as follows:
• If there is no other G15 inside the associated subroutine, the G15 will be executed after the
subroutine.
• If there is another G15 inside the associated subroutine, it will execute this G15 without calling
the subroutine and after executing the associated subroutine, it will not execute the G15 again.
This feature may be used to change the set of drive parameters when switching from spindle mode
to C axis mode.
TYPCROSS (P135)
It indicates how cross compensation is applied. This parameter has two digits.
(units) Cross compensation with theoretical or real coordinates.
The units indicate whether cross compensation is applied with theoretical coordinates or with real
ones.
(tens) The cross compensation on Gantry axis affects the slave axis
The tens indicate whether cross compensation on Gantry axes affects only the master axis or both.
Value Meaning
0 It is not permitted.
1 It is permitted. The withdrawal stops at the M functions.
2 It is permitted. The withdrawal does not stop at the M functions.
Default value: 0
Possible values
Integer numbers between 0 and 9999.
Default value: 0 (no associated subroutine)
Value Meaning
x0 With real coordinates.
x1 With theoretical coordinates.
Default value: 0
Value Meaning
0x It affects the master axis.
1x It affects both axes.
Default value: 0
