6.2.1
Conducted 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.
6.2.2
Power sequencing
The drive does not require power sequencing. The drive protects against inadvertent writing during power-up
and down.

Current profiles
The +12V and +5V current profiles for the ST973401SS and ST936701SS models are shown below in the fol-
lowing figures.
Note:
All times and currents are typical. See Tables 12 and 13 for maximum current requirements.
