5.4 CHANGING THE PIERCING TIME
Overview
When the C-series or Y-series oscillator is used, external signals can
be used to change the piercing time specified by G24.
When the CNC executes G24, it presets the timer to the specified
piercing time. While the timer is counting down, piercing is executed.
Reducing the piercing time
When the piercing time reduction signal (PTS) is set to 1 during
piercing, the timer set for the piercing time stops counting down at the
rising edge of the signal and piercing stops.
Extending the piercing time
When the piercing time extension signal (PTE) is set to 1 during
piercing, piercing does not stop when down-counting by the timer
ends. The piercing continues until the piercing time extension signal
(PTE) is set to 0.
The following block diagram indicates the piercing operation.
Updating the piercing time
The piercing time can be updated to an extended or reduced value. As
shown in the block diagram, piercing time R, specified by G24 R_; is
stored as active data. When the piercing time is changed by the
piercing time reduction signal (PTS) or piercing time extension signal
(PTE), the update data is prepared by means of time measurement.
When bit 1 (HPT) of parameter No.15003 is set to 0, the update data
replaces the active data.
To execute piercing with the updated time, specify the next G24
command without R. If G24 is specified with R, the updated time is
replaced with the value for R.
If cutting conditions have been specified using the cutting condition
setting function, the piercing time stored in the data area for the
cutting condition setting function is valid at all times and, therefore,
the active data cannot be changed.
