Measured with an average reading DC ammeter. Instanta-
neous +12V current peaks will exceed these values.

A –10% tolerance is permissible during initial start of the spin-
dle but must return to ±5% before reaching 5400 r/min. The
±5% must be maintained after the drive signifies that its
power-up sequence has been completed and that the drive is
able to accept selection by the host initiator.

See the +12V current profile  in the
