6 -2Application and Overload Selections Select the Overload to Suit the ApplicationSet C6-01 (CT: Low carrier constant torque, VT: High carrier variable torque) depending on the applicationfor which the Inverter is used. The setting ranges for the Inverter carrier frequency, overload tolerance, andmaximum output frequency depend on the setting in C6-01.Related Constants* 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-terV/fV/fwithPGOpenLoopVec-torFluxVec-torC6-01 CT/VTselection0: CT (low carrier, constant torque,150% per minute)1: VT (high carrier, variable torque,120% per minute)0 or 11 *1No Q Q Q Q 223H0 *1C6-02Carrier fre-quencyselectionSelect 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 224HC6-03*4Carrierfrequencyupper limitSet the carrier frequency upper limit andlower limit in kHz units.The carrier frequency gain is set as fol-lows:With the vector control method, theupper limit of the carrier frequency isfixed in C6-03.K is a coefficient that depends on thesetting 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 225H2.0 to2.5 2.0 kHzC6-04*4Carrierfrequencylower limit0.4 to15.0*315.0kHz*2 No A A No A 226H2.0 to2.5 2.0 kHzC6-05*4Carrier fre-quency pro-portionalgain00 to99 00 No A A No A 227HCarrier frequencyOutput frequency x (C6-05) x K(Max. output frequency)Outputfrequency
