3770 Axis as the calculation reference in constant surface speed control
[Data type] Byte
[Valid data range] 1, 2, 3, ..., number of control axes
Set the axis as the calculation reference in constant surface speed control.
NOTE
When 0 is set, constant surface speed control is always
applied to the X–axis. In this case, specifying P in a G96
block has no effect on the constant surface speed control.
3771 Minimum spindle speed in constant surface speed control mode (G96)
[Data type] Word
[Unit of data] min

[Valid data range] 0 to 32767
Set the minimum spindle speed in the constant surface speed control
mode (G96).
The spindle speed in constant surface speed control is clamped to the
speed given by parameter 3771.
