- 676 -
7643 Polygon synchronous axis in spindle-spindle polygon turning
[Input type] Parameter input
[Data type] Byte path
[Valid data range] 0 to Maximum number of controlled axes (Common to the system)
This parameter sets the polygon synchronous (slave) axis in
spindle-spindle polygon turning.
NOTE
1 Spindle-spindle polygon turning is enabled only for
serial spindles.
2 This parameter is invalid if either parameter No.
7642 or No.7643 is set to 0. In this case, the
settings of parameter No. 7640 and No.7641 are
valid.
3 When a spindle other than the first serial spindle is
used as a master axis, the multi-spindle control
option is required to specify an S command for the
master axis.
4 When the PMC window function or G10 command
is used to rewrite this parameter, rewrite this
parameter before the block specifying the
spindle-spindle polygon command G51.2. When
the PMC window function is used to rewrite this
parameter in the block immediately before G51.2,
specify the rewriting of this parameter by using an
M code (parameter No. 3411 and up) without
buffering.
5 A spindle number common to the system is to be
set in this parameter. When using this parameter,
set 0 in parameter No. 7640 and No. 7641.
Alarm and message
Number Message Description
PS0194 SPINDLE COMMAND IN
SYNCHRO-MODE
A Cs contour control mode, spindle positioning command, or
rigid tapping mode was specified during the spindle
synchronous control mode or simple spindle synchronous
control mode.
PS0218 NOT FOUND P/Q COMMAND P or Q is not commanded in the G51.2 block, or the command
value is out of the range. Modify the program. For a polygon
turning between spindles, more information as to why this alarm
occurred is indicated in DGN No. 471.
PS0219 COMMAND G51.2/G50.2
INDEPENDENTLY
G51.2 and 50.2 were specified in the same block for other
commands. Modify the program in another block.
PS0221 ILLEGAL COMMAND IN
SYNCHR-MODE
Polygon machining synchronous operation and axis control or
balance cutting are executed at a time. Modify the program.
