Measured with average reading DC ammeter. Instant12V current peaks will exceed these val-
ues. Power supply at nominal voltage. N (number of drives tested) = 6, 35 Degrees C ambient.
[2]
For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ±5% before reaching
15000 RPM. 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.
[3]
See +12V current profile in Figure 1.
[4]
This condition occurs when the Motor Start option is enabled and the drive has not yet received a Start
