3704 PCS
Data type : Bit
PCS In Multi-spindle Control, 3rd/4th spindle position-coders are:
0: unavailable
1: available
Position-coders for 3rd/4th serial spindles can be used.
2nd/3rd/4th position-coder selection signals are used for selection.
NOTE1) It is available only with Multi-spindle Control option.
NOTE2) When switching position-coder feedback between 2 paths (by the
signals SLPCA<G064.2> and SLPCB<G064.3>), the same setting of
this parameter is required between paths.

PG2, PG1 Specify gear ratio between spindle and 1st spindle position-coder.
P22, P21 Specify gear ratio between spindle and 2nd spindle position-coder.
P32, P31 Specify gear ratio between spindle and 3rd spindle position-coder.
P42, P41 Specify gear ratio between spindle and 4th spindle position-coder.
Magnification PG2,P22,P32,P42 PG1,P21,P31,P41
*1 0 0

Magnification = Spindle rotation number / Position-coder rotation number
NOTE1) 2nd to 4th spindles are available only with Multi-spindle Control option.
NOTE2) 3rd/4th spindle position-coders are available only when the
parameter PCS(No.3704#6) is “1”.
