7.2.1Conducted noise immunity

Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.

+5 V	=	250 mV pp from 0 to	20 MHz.
+12 V	=	800 mV pp from 100	Hz to 8 KHz.

450 mV pp from 8 KHz to 20 KHz.

250 mV pp from 20 KHz to 5 MHz.

7.2.2Power sequencing

The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down.

7.2.3Current profiles

The +12V and +5V current profiles are shown in the following figures.

Note: All times and currents are typical. See Section 7.2 for maximum current requirements.
