Figure 1. Typical startup and operation current profile

1.7.1.1Typical current profile

Figure 1 shows a projected drive startup and operation current profile for the Marathon 2250 and the Marathon 1680.

Note. The peaks in Figure 1 are the result of inductive kickback from the commutation of the spindle motor and, therefore, do not draw power from the battery.

1.7.2Power recovery

Except during execution of a write command or writing cached data, the drive’s power can be interrupted without adversely affecting the drive or previously written data. If power is removed while the drive is performing a write operation, the integrity of the data being written cannot be guaranteed.

Note. Do not remove power from the drive while the interface signals are ac- tive (at low impedance) because power may enter the input buffers.

1.7.3Conducted noise

The drive is expected to operate with a maximum of:

∙150 mV peak-to-peak triangular-wave injected noise at the power connector. The frequency is 10 Hz to 100 KHz with equivalent resistive loads.
