Spindle Synchronization
Chapter 15
15-8
Function
This parameter determines the maximum amount of positional deviation
allowed between synchronized spindle markers after synchronization is
achieved. When this maximum deviation is exceeded, the PAL flag,
$SYNE is set.
Parameter
Number
[595]
Range
0.000 to 360.000 degrees
Notes
This is a global parameter. The value set here applies to both spindles.
Maximum synchronization accuracy will depend on following error
stability when synchronization is achieved.
Function
This parameter determines the maximum amount of positional deviation
allowed between synchronized spindle markers before synchronization is
achieved.
Parameter
Number
[596]
Range
0.000 to 360.000 degrees
Notes
This is a global parameter. The value set here applies to both spindles.
The Spindle Deviation Tolerance parameter in spindles 1, 2, and 3 also
effects how closely the spindles are synchronized.
