PARAMETER DESCRIPTION 187
5.7.4 Decrease carrier protection setting

It selects decrease carrier or decrease rated current protection by setting parameters.
Parameter Name Default Setting Range Content
06-07
P.263 Decrease carrier
protection setting
0
0
Fixed carrier frequency, and limit output current according to
carrier value.
1
Fixed rated current, and limit carrier according to output
current and temperature.
Decrease carrier protection

06-07(P.263)=0, fixed carrier frequency, but the rated current of inverter will be reduced according to set carrier
frequency and corresponding curve, so as to avoid overheating of IGBT module on inverter:
