20 Medalist Pro Installation Guide, Rev. B

±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 the +12V current profile in the Medalist Pro Product Manual (publication number 32661-001).

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

[5]See “Conducted noise immunity” in the Medalist Pro Product Manual. The specified voltage tolerance is inclusive of ripple, noise, and transient response.

[6]Operating condition is defined as random seek read opera- tions with a block count of 64.

General Notes for Tables 2a and 2b:

1.Minimum current loading for each supply voltage is not less than 4% of the maximum operating current shown.

2.Use separate ground returns for +5V and +12V supplies.

3.Where power is provided to multiple drives from a common supply, carefully consider individual drive power require- ments. Where multiple units are powered on simultaneously, be sure the peak starting current is available to each device.
