Synchronizing spindles
in multiple drive configurations
If you are installing two or more Elite 9 drives, you may (optionally) synchronize their spindles to reduce the latency associated with switching from one drive to another.
Spindle sync cables are used to connect the drives.
Use pins 23 and 24 on the J4A connector to attach the spindle sync cable. Pin 24 provides the reference index signal (SSREF+) and pin 23 provides ground (GND). See Figure 8.
