FPR
#1 #0
[Data type] Bit
FPR Specifies whether to use a function that converts the specified spindle
rotation speed to the actual spindle rotation speed in feed--per--revolution
mode, that is, the feed--per--revolution function with no position coder.
0: Notused.
1: Used.
NOTE
If you set this parameter to 1, reset parameter NPC (bit 0 of
parameter No. 1402) to 0.
3741 Maximum spindle speed for gear 1
3742 Maximum spindle speed for gear 2
3743 Maximum spindle speed for gear 3
3744 Maximum spindle speed for gear 4
[Data type] Word
[Unitofdata] rpm
3770 Axis as the calculation reference in constant surface speed contorol
[Data type] Byte
[Valid data range] 0, 1, 2, 3, ..., number of control axes
set the axis as the calculation reference in constant surface speed contorol.
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.
