If the Spindle Remote/Local switch on the CE panel behind the front panel
is set to Local, it enables rotation of the spindle motor. When the DC
motor comes up-to-speed, the heads start Initial Seek operation and stop
on cylinder zero. Approximately 40 seconds later the Ready LED lights.
The spindle motor stops rotating approximately 15 seconds after the switch
is set to the Off position.
When the Remote/Local switch is set to Remote, the spindle motor starts
and stops rotating in accordance with the Spindle Sequence Pick/Hold
commands issued from the controller if the Start switch is On.
