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 5,357 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
Elite 47 Product Manual
(publication number 83329280).

This condition occurs when the Motor Start option is enabled
and the drive has not yet received a Start Motor command.

See “Conducted noise immunity” in the
Elite 47 Product Man-
ual.
The specified voltage tolerance is inclusive of ripple,
noise, and transient response.

At power-up, the motor current regulator limits the +12V cur-
rent to an average value of less than 4.8A, although instanta-
