RETRACTE (P186)
It enables or disables the various retraction (withdrawal) options in a drilling or a mill type threading.
0 Value: disabled.
1 Value: enabled.
TAPTYPE (P188)
This version improves the rigid tapping speed. This is especially useful in processes where it is
continuously thread cutting.
If bit 0 of g.m.p. TAPTYPE (P188) = 1, the M3, M4 and M5 that are executed in rigid tapping appear
in the history, but they are not sent to the PLC. Since these M's are not sent to the PLC, the dwells
associated with them are eliminated and, consequently, the cycle is faster.
MANTFCON (P198)
While executing in look-ahead (G51), some blocks of the program cause the feedrate to slow down
almost to zero causing a square-corner effect. To avoid this effect, when G05 or G51 have been
programmed, it is necessary to maintain the machining feedrate of the blocks that cause it.
To maintain the machining feedrate of these blocks and avoid the square-corner effect, change bit
0 of general machine parameter MANTFCON (P189).
This parameter has 16 bits counted from right to left.
Bit 0 of g.m.p. MANTFCON (P189):
Bit Meaning
0 Enables / disables the threading withdrawal in the threading cycles (G86 and
G87). Only for the lathe model.
1 Enables / disables the threading withdrawal in the drilling cycles (G69, G81,
G82 and G83). Only for the mill model.
2 Enables / disables the threading withdrawal in the tapping cycle (G84). Only
for the mill model.
3 Enables / disables the threading withdrawal in the rigid tapping cycle (G84).
Only for the mill model.
Default value 0
Bit 0 Meaning
0 Regular rigid tapping.
1 Rigid tapping and without sending M functions to the PLC.
Default value 1
Value Meaning
0 Motionless blocks are executed in square corner mode.
1 Motionless blocks maintain the feedrate and are not executed in square
corner mode.
