Set Values
Value Description
0 Low carrier frequency at low speed disabled.
1 Low carrier frequency at low speed enabled.
·Normally set n175 to 0 (except for 5.5 and 7.5kW Inverters).
·Whentheoutputfrequencyis5Hzorless andtheoutputcurrentrate is110%ormore,
the carrier frequency will be automaticallyreduced to 2.5 kHzwith n175 setto1. 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 n080 for carrier frequency.
