B–63610EN/01
166
The target spindle of synchronous spindle control is specified in
parameters No. 4831 to 4832.
In addition, the following signals affect the control.
Synchronous spindle signal of each spindle
SPSYC1 to SPSYC2 <G288 bits 0 to 1>
Signal of synchronous control of the spindle phase for each spindle
SPPHS1 to SPPHS2 <G289 bits 0 to 1>
SSY Simple synchronous spindle control by each spindle is:
0 : Not performed.
1 : Performed.
The master axis and slave axis of simple synchronous spindle control can
be selected from the first to second spindles.
The target spindle of simple synchronous spindle control is set in
parameters No. 4821 to No. 4822.
In addition, the following signals affect the control.
Signal of simple synchronous control of each spindle
ESSYC1 to ESSYC4 <G264 bits 0 to 3>
Parking signal of simple synchronous control of each spindle
PKESE1 to PKESE4 <G265 bits 0 to 3>
CSS On the second spindle, 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
NOTE
1 A single spindle cannot be specified as multiple axes of Cs
contour control.
2 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–––;).
