Machine coordinate display
As for the axis whose the signal EAX* <Gn136> for control axis select (PMC axis control) is 1, the
machine coordinate shows the actual machine coordinate (the machine position from the reference
position) regardless of the bit 7 (PGM) of parameter No. 11320 and bit 4 (PGA) of parameter No. 3115
setting.
-
Workpiece coordinate system preset
Please set the bit 6 (WPS) of parameter No. 3006 to 1 to do workpiece coordinate system preset
automatically at the end of the high-speed program check mode.
When the workpiece coordinate system preset is commanded by the soft key operation or input signal
during the high-speed program check mode, the workpiece coordinate system is established based on the
actual machine coordinate.
WARNING
When the coordinate system is set before the high-speed program check mode is
turned on by the work coordinate system setting G92 (machining center system
and G code system B or C of the lathe system), G50 (G code system A of the
lathe system) and the local coordinate system setting G52, their setting values
are deleted by the execution of the work coordinate system preset.
-
Reference Position Return (G28)
The alarm PS5364 occurs when the reference position is not established and G28 is specified during the
high-speed program check mode.
-
Machine Lock Signal
During the high-speed program check mode, all-axis machine lock signal MLK <Gn044.1> and each-axis
machine lock signals MLK1 to MLK8 <Gn108> are invalid except for PMC control axis.
-
Control axis select signal (PMC axis control)
In case that the bit 3 (PGR) of parameter No. 3454 is set to 1, the alarm PS5364 occurs when the signal
EAX* <Gn136> for control axis select (PMC axis control) is changed from 0 to 1 or from 1 to 0 during
the high-speed program check mode.
-
Save / restore of data
The save/restore of the data before/after the program check of the high-speed program check function is
realized by saving all data before the program check and restoring all data after the program check.
Therefore, even when the data is changed without the program command such as the PMC window
during the program check, the changed data returns to the value before the program check.
-
Restore of data
When the power off request alarm is generated during the high-speed program check mode and the CNC
power is turned off immediately, the changed data still remain. Therefore, if a restore of data is necessary,
turn off the CNC power after ending the high-speed program check mode and restoring the saved data.
-
Programmable parameter input (G10)
The bit 3 (PGR) of parameter No. 3454 and the bit 6 (PGS) of parameter No. 3001 can not be changed by
programmable parameter input (G10). When G10 L52 is commanded to these parameter bits, the alarm
PS5364 occurs.
-
Cycle start
In case that the bit 3 (PGR) of parameter No. 3454 is set to 1, the signal ST <Gn007.2> for cycle start are
invalid during the data saving and restoring.
