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.
+5V
0 to 100 kHz
150mV
100 kHz to 10 MHz
100mV
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.
Note: All times and currents are typical. See Table 2 for maximum current requirements.
