0 Low carrier frequency at low speed disabled.
1 Low carrier frequency at low speed enabled.
•Normally set n75 to 0.
•When
the output frequency is 5 Hz or higher and the output current rate is 1 10% or less,
the carrier frequency will be automatically reduced to 2.5 kHz with n75 set to 1. If the
load is heavy at low speed, the Inverter will withstand higher overcurrent by suppres -
sing the heat radiation of the Inverter caused by the carrier frequency.
•This function is enabled with 2, 3, or 4 set in n46 for carrier frequency.
