[1]

Measured with average reading DC ammeter or equivalent sampling scope. Instantaneous +12V current 
peaks will exceed these values. 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
