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.
6.2.3
Current profiles
The +12V and +5V current profiles are shown below in figure 1.
Note:
All times and currents are typical. See Table 12 for maximum current requirements.
+5V
=
250 mV pp from 0 to 100 kHz to 20 MHz
+12V
=
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
