*K is the coefficient determined by the set value in C6-03.
C6-03 Š 10.0 kHz: K=3
10.0 kHz > C6-03 Š 5.0 kHz: K=2
5.0 kHz < C6-03: K=1
•
To fix the carrier frequency, set C6-03 and C6-04 to the same value or set C6-05 to 0.
•
If Carrier Frequency Proportional Gain (C6-05) < 6 and C6-03 < C6-04, OPE11 (Data setting error) will
occur.
Carrier Frequency and Inverter Overload Current Level
When using a 200 V Class Inverter 30 to 110 kW or a 400 V Class Inverter for 30 to 160 kW with a carrier fre-
quency higher than 10 kHz, the Inverter overload level will be reduced. Even when the overload current is
below 120%, in this case an OL2 (Inverter overload) will be detected. The Inverter overload current reduction
level is shown below.
