1. AXIS CONTROL
183
(2)To resume the ordinary workpiece coordinate system automatically
when terminating synchronous control
Set parameter SPSx (parameter No. 8163) to “1”.
Set parameter No. 1250 with the master axis coordinates in the
workpiece coordinate system when the master axis is at the reference
position.
This synchronous control can be specified using the synchronous control
axis selection signal (SYNC1 to SYNC7) similarly to the ordinary
synchronous control. When the signal is raised to start synchronous
control, a workpiece coordinate system for the master axis is
automatically set up. When the signal is dropped to terminate
synchronous control, the original workpiece coordinate system for the
master axis is resumed automatically.
(1)Workpiece coordinate system for synchronous control
(Master axis workpiece coordinate value)
= (parameter No. 8185 for the master axis)
" (slave axis machine coordinate value) . . . . . .
+ (master axis machine coordinate value) . . . . .
+: Master axis parameter SCDx (bit 4 of parameter No. 8163) = 0
–: Master axis parameter SCDx (bit 3 of parameter No. 8163) = 1
Master axis parameter SCMx (bit 3 of parameter No. 8163) = 1 only
(2)Workpiece coordinate system for ordinary operation
(Master axis workpiece coordinate value)
= (parameter No. 1250 for the master axis)
+ (master axis machine coordinate value)
CAUTION
1 The same least command and input increments must apply
to both master and slave axes.
2 If synchronous control that involves automatic coordinate
system setting is started or terminated during automatic
operation, a move command or other commands that
reference the current position of an axis may not be
specified in the current block and the next one or two (during
tool–nose radius compensation) blocks, except when the M
code in the current block does not involve buffering.
