AC30 series Variable Speed Drive
Functional Description
The Drive provides a unique quiet pattern PWM strategy in order to reduce audible motor noise. The user is able to select between the quiet pattern
or the more conventional fixed carrier frequency method. With the quiet pattern strategy selected (RANDOM PATTERN enabled), audible motor
noise is reduced to a dull hiss.
In addition, the user is able to select the PWM carrier frequency. This is the main switching frequency of the power output stage of the Drive. A high
setting of carrier frequency (e.g. 6kHz) reduces audible motor noise but only at the expense of higher Drive losses and smooth motor rotation at low
output frequencies. A low setting of carrier frequency (e.g. 3kHz), reduces Drive losses but increases audible motor noise.
