Conducted noise
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
=
250 mV pp from 100 Hz 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.
