Forward/Reverse Enable; 2-Wire/3-Wire Operation Control Modes - Delta Electronics AC Drive VFD-F Series User Manual

The Carrier frequency of the PWM output has a signification influence on the
electromagnetic noise, heat dissipation of the AC drive, and the acoustic noise to the motor
as shown in the following chart.
Carrier
frequency
Signification
Minimal
When the carrier frequency is low, current ripple of the AC drive is large. This may result in
a current display value greater than the actual value.
