original workpiece coordinate system for the master axis
automatically. Note that the workpiece coordinates of a salve axis
can be automatically set through appropriate parameter setting at the
end of synchronous control only.
- Setting and commands
In addition to setting ordinary synchronous control, parameters must
be specified as follows:
(1) To set up a workpiece coordinate system for synchronous control
automatically when starting synchronous control
Set parameter SPMx (No. 8163#1) to "1".
Set parameter No. 8185 with the coordinates of the slave axis
reference position relative to the coordinates of the master axis
when the master axis is at the reference position.
(2) To resume the ordinary workpiece coordinate system
automatically when terminating synchronous control
Set parameter SPSx (No. 8163#2) to "1". (Only the parameter
of the master axis.)
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 signals (SYNC1 to SYNC8) similarly to
the ordinary synchronous control. When the signals are raised to
start synchronous control, a workpiece coordinate system for the
master axis is automatically set up. When the signals are dropped
to terminate synchronous control, the original workpiece
coordinate system for the master axis is resumed automatically.
- Workpiece coordinate calculation method
(1) Workpiece coordinate system for synchronous control
(Master axis workpiece coordinate value)
= (parameter No. 8185 for the master axis)
± (slave axis machine coordinate value) . . . <1>
+ (master axis machine coordinate value) . . . <2>
<1> +: Master axis parameter SCDx (No. 8163#4) = 0
-: Master axis parameter SCDx (No. 8163#4) = 1
<1> Master axis parameter SCMx (No. 8163#3) = 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
CAUTION
The same least command and input increments
must apply to both master and slave axes.
