User Constant Tables5- 25Carrier Frequency: C6User constants for the carrier frequency are shown in the following table.* 1. Only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters.* 2. The factory settings depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.* 3. The setting ranges depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.* 4. This constant can be monitored or set only when F is set for C6-02.Con-stantNum-berName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terPageV/fV/fwithPGOpenLoopVec-torFluxVec-torC6-01 CT/VTselection0: CT (low carrier, constant torque,150% per minute)1: VT (high carrier, variabletorque, 120% per minute)0 or 11*1No Q Q Q Q 223H4-54-206-20*1C6-02CarrierfrequencyselectionSelect carrier wave fixed pattern.0: Low-noise PWM1: 2.0 kHz2: 5.0 kHz3: 8.0 kHz4: 10.0 kHz5: 12.5 kHz6: 15.0 kHzF: Enables detailed settings usingconstants C6-03 to C6-050,1(C6-01=0)0 to F(C6-01=1)1(C6-01=0)6 *2(C6-01=1)No Q Q Q Q 224H4-64-184-196-2C6-03*4CarrierfrequencyupperlimitSet the carrier frequency upperlimit and lower limit in kHz units.The carrier frequency gain is set asfollows:With the vector control method, theupper limit of the carrier frequencyis fixed in C6-03.K is a coefficient that depends onthe setting of C6-03.C6-03 ≥ 10.0 kHz: K = 310.0 kHz > C6-03 ≥ 5.0 kHz: K = 25.0 kHz > C6-03: K = 12.0 to15.0*315.0kHz*2 No A A A A 225H 6-22.0 to2.52.0kHzC6-04*4Carrierfrequencylowerlimit0.4 to15.0*315.0kHz*2 No A A No A 226H 6-22.0 to2.52.0kHzC6-05*4Carrierfrequencypropor-tional gain00 to99 00 No A A No A 227H 6-2Carrier frequencyOutput frequency x (C6-05) x K(Max. output frequency)Outputfrequency
