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.

7700 HDR HBR
[Input type] Parameter input
[Data type] Bit path
# 0 HBR When the electric gear box (EGB) function is used, performing a
reset:
0: Cancels the synchronous mode (G81 or G81.5).
1: Does not cancel the synchronous mode. The mode is canceled
only by the G80 or G80.5 command.
# 2 HDR Direction for compensation for a helical gear (usually, set 1.)
(Example) To cut a left-twisted herical gear when the direction of
rotation about the C-axis is the negative (-) direction:
0: Set a negative (-) value in P.
1: Set a positive (+) value in P.
