4. DESCRIPTION OF PARAMETERS
195
PCS If the third or fourth serial spindle is connected under multi–spindle
control, the third or fourth position coder selection signal (PC3SLC,
PC4SLC <G026 bits 0 and 1>) is:
0 : Not used.
1 : Used.
NOTE
If the position coder feedback is exchanged between paths
under multipath control of T series (spindle feedback
selection signals SLPCA and SLPCB <G064 bits 2 and 3>),
set this parameter to the same setting for the paths.
The fourth serial spindle can be used just in Series 16i.
CSS On the second to fourth spindles, Cs contour control is:
0 : Not performed.
1 : Performed.
If Cs contour control is performed on each spindle as specified by this
parameter, set parameter No. 1023 as indicated below.
Setting
–1 = Axis of Cs contour control by the first spindle
–2 = Axis of Cs contour control by the second spindle
–3 = Axis of Cs contour control by the third spindle (Series 16i/18i
only)
–4 = Axis of Cs contour control by the fourth spindle (Series 16i only)
NOTE
1 A single spindle cannot be specified as multiple axes of Cs
contour control.
2 Under multipath control, a spindle of another path cannot be
assigned.
3 This parameter cannot be used with the spindle positioning
function. When using the spindle positioning function, set bit
7 (CSS) of parameter No. 3704 to 0.

[Data type] Bit
ESF When the spindle control function (Spindle analog outpu or Spindle serial
output) is used, and the constant surface speed control function is used or
bit 4 (GTT) of parameter No.3705 is set to 1:
0 : S codes and SF are output for all S commands.
1 : S codes and SF are not output for an S command in constant surface
speed control mode (G96 mode) or for an S command used to specify
maximum spindle speed clamping (G50S–––;).
