MXC
[Data type] Bit
MXC During mixed control of the X– or Z–axis, measurement direct input
function B for tool compensation performs calculation based on:
0 : Machine coordinates for the path being controlled
1 : Machine coordinates for another path subject to mixed control
NOTE
1 This parameter is valid for setting tool compensation values
for the X– or Z axis and setting shift of the workpiece
coordinate system for the Z–axis.
2 This parameter cannot be used when mixed control is
applied to paths for which different minimum command
increments (metric or inch) are specified.
XSI When MXC = 1, the machine coordinates along the X–axis for the other
path subject to mixed control are fetched:
0 : With the sign as is
1 : With the sign inverted
ZSI When MXC = 1, machine coordinates along the Z–axis for the other path
subject to mixed control are fetched:
0 : With the sign as is
1 : With the sign inverted
NCS If an overtravel alarm is issued for an axis under synchronous, composite,
or superimposed control, synchronous, composite, or superimposed
control is:
0 : Released.
1 : Not released.
If an overtravel alarm is issued for an axis under synchronous, composite,
or superimposed control, the following operation is performed according
to the setting of this parameter:
When NCS is set to 0 P/S alarm No. 255 may be issued together with the
overtravel alarm. In this case, place the machine in the emergency stop
state once, then release the alarm.
When NCS is set to 1 The machine decelerates, then stops with a delay
of 8 msec in comparison with an ordinary overtravel alarm.
SPE The synchronization deviation is:
0 : The difference between the positioning deviation of the master axis
and that of the slave axis.
1 : The difference between the positioning deviation of the master axis
and that of the slave axis plus the acceleration/deceleration delay.
