2.4.23 Withdrawal the tool.
RETRACTENABLE
Enable tool withdrawal.
This parameter shows the parameter table to enable tool withdrawal (retraction) in various
situations.
RETRACTTHREAD
Enable tool withdrawal (retraction) in threading.
Possible values: ON / OFF.
Default value: ON.
Associated variable: (V.)[ch].MPG.RETRACTTHREAD
This parameter defines the CNC behavior when interrupting a threading ([STOP] key or PLC
mark _FEEDHOL).
2.4.24 Master spindle.
MASTERSPDL
Master spindle maintained.
Possible values: Temporary / maintained.
Default value: Temporary.
Associated variable: (V.)[ch].MPG.MASTERSPDL
This parameter indicates whether the channel keeps the current master spindle or recovers
its original master spindle after executing M02, M30 or after an emergency or reset or
restarting the CNC.
When a channel does not keep its master spindle, on CNC power-up and after a reset, the
channel assumes as master spindle the first spindle defined by the machine parameters of
the channel (original master). If this spindle is parked or "handed out" to another channel,
the channel assumes as master spindle the next spindle defined by the machine parameters
and so on. If the channel does not have spindles of the original configuration (the one defined
by the machine parameters) because they are parked or "handed out", it assumes as master
spindle the first one of the current configuration that is not parked.
Exchanging spindles between channels.
When spindles are being exchanged between channels, the behavior of this parameter also
depends on parameter AXISEXCH that sets whether the channel change of a spindle is
temporary or permanent. If the current master spindle of the channel is a spindle "loaned"
by another channel and its permission to change channels is temporary (AXISEXCH =
Temporary), the spindle returns to its original channel.
RETRACTENABLE
RETRACTTHREAD Enable tool withdrawal (retraction) in threading.
RETRACTTHREAD Meaning.
OFF The CNC stops the axes at the end of the pass.
ON • In electronic threading (G33/G34), function G233 defines the distance
that the axes withdraw from the part. If G233 is not active, the axes stop
at the end of the pass.
• In threading canned cycles, (-T- model), both ISO and conversational,
the CNC withdraws the axes from the part. The distance that the tool
withdraws depends on how the cycle is programmed.
MASTERSPDL Meaning.
Temporary. The channel recovers its original master spindle if it is free; otherwise, it selects
as master the firs spindle available in the original configuration.
Maintained. The channel keeps the active master spindle.
